Ohm Walsh Talls and amplification

Ok, I am perplexed and I would appreciate any feedback you can give me. I am interested in getting a pair of Ohm Tall speakers. Initially (based off from Steve Guttenberg's and Zeos' reviews) i assumed that the 2000s were the ones for me. I don't see where Zeos' or Steve's rooms are any bigger than mine but, I measure the square footage of my room last night and it's only 353 square feet! Zeos himself even said that the 1000s were the correct size for his room, but he just wanted to go bigger. So, my first question is: Can you use a bigger Ohm Tall than what your room requires (as Zeos does)? Also, these speakers seem to love power. Steve drove his with a Mytek amp and a big Pass Labs amp. I cannot afford  Pass Labs and, the Mytek...well, I *could* maybe swing that but, Zeos uses a pair of Crown amps that are not made for audio but for DJs and live entertainers, etc. Obviously, he's very happy with the results. I finally did call John Strohbeen and he confirmed that the Talls love power... he suggested Mytek, Peachtree, certain NAD models, and Emotiva as affordable amps that have good results. I then asked him about Zeos using the Crown amps and he said, "Yeah, that's another way to go that's very affordable." I asked him if the sound was good and he said, "Yeah, it sounds good. In fact, we used something like Crown that here in our factory for quite a while." So, my second question is: what success have you had in the way of amplification with your Ohm Talls? 
For starters, use cubic feet and Ohms chart for the correct speaker, so if your ceilings are 8’, then your measurement is going to be 2824, which puts you right at the upper edge of the 2000. Sometimes with overlapping numbers, you can chose based on budget and quality of bass end you require. If you have more questions or concerns, John or Evan can assist you further on the matter. Sometimes, there are no hard rules, but recommendations based on experience. Every room can be different based on materials of construction, how well or not it is damped, etc.

As to the amplification end, a budgetary number may help readers here give you potential recommendations. I always felt my Ohms liked the power/current drive in general, as to whether or not a pro audio amplifier versus a typical “audiophile” model will do things any better or differently ultimately comes down to your own ears, use them!

I am sure there will be the usual suspects along to assist! Have fun!
You’ve gotten good advice from John Strohbeen.

Yes they like power and current so throw as much of that at them as you can within your particular budget.

Class D amps in general are a very good way to go.

There is a calculator on the Ohm site to help pick the speaker based on room measurements. That’s as cut and dry as it gets.

Getting speakers that are too big will just produce too much bass in the room. No advantage. If you are a bass hound, maybe go one size larger rather than smaller given the choice.

Or if you have the budget and want the flexibility to use in different size rooms best, spring for the 5000 series that has on board adjustments to fit most any room.
Ah, okay. Cubic feet makes sense! Turns out my guesstimation was not far off the mark: 2824 cubic feet puts me in the 2000 Tall category (or 3000s if I wanted). 
Class D amps are generally not good current sources. They tend to have minimal headroom and weak power supplies. This is why a 200 watt/ch AB MOSFET amp will usually sound more powerful than a 400watt/ch class D amp. 

Some will contend otherwise but that has been my experience. Certainly there are exceptions out there but probably not in any class D amp that's been around for more than a few years. That tech has only recently begun to sound decent. 

I'd look at the power supply of the amp first and foremost. Investigate whether it has a large transformer and large filter caps? (look for something at least 20K microfarads/channel).

The Parasound Hint6 is a high-current amp and can drive almost anything. I'm told Naim amps are as well. 

I hear what you're saying, Helomech. The thing is, John Strohbeen himself recommended a handful of class D amps for pairing with his speakers. 
That said, I have heard good things about the Hint6. I'll look into that.

Switching power supplies for Class D amps can be very compact circuit boards and need not be big and bulky like traditional amps.

A good exsmple is BelCanto ref1000m amps that are the bomb with my Ohm Walsh speakers. They deliver up to 45 amps peak current.

In general if the amps specs indicate doubling or near doubliing of power from 8 to 4 ohms that  is a good indicator in lieu of specific current delivery specs. 

I think any decent amp can power them up just fine. They will however respond quite well to added power and upstream upgrades. I’m very surprised how revealing they are compared to others I’ve owned of differences in sources.

As for the size, I think they perform remarkably well size for size. That said, I think John might undersize them just a shade if you like a little bass/impact. Also, look at the room construction and floor substrate.  I have a dedicated room in my finished basement, but it's padding and carpet over concrete.  No question the concrete floor benefits from a bigger speaker/ability to put out bass.

My room is 13 x 17, closed, 9ft ceiling. The 2000’s would work. I have some 5000’s (and I have the treble and midrange in the + position, midbass and low bass in the neutral) and love them in here.

That said, I just had some Pro-200’s upgraded to Pro 3000’s (pretty nice!), and they do a pretty darn good job of thumping the room. One they broke in a bit, remarkable what they do for their size. While my 5000’s are the "square" cabinets, the Pro 3000’s use 3000 drivers on a round "cabinet". I think there are some advantages to the round cabinets.

The 3000’s bass I would be very happy with without a subwoofer also, just like the 5000’s. That said the 5000’s can absolutely thump the room. The 3000’s thump/punch, but not quite like the 5000’s. They might sound a shade tighter though.

Ultimately I’ll likely sell either my 5000’s or 3000’s as I have another pair of speakers being built. But, I’ll keep one set I suspect for another room.  The OHM's do some very cool, fun things.

I can strongly recommend BelCanto c5i digital  integrated amp with the Ohms. Only 60w/ch though so no concert level volumes perhaps.

For a more powerful integrated amp, I really like the tube/Class D hybrid Rogue Pharoah or even its smaller brother the Sphinx.

The Rogue Pharaoh is severely lacking in grunt. I've owned both the Sphinx and the Pharaoh and neither are high-current amps in practice. One owner on the Steve Hoffman Forum had a lot of difficulty driving his Maggie 1.7s with it. He switched to a PrimaLuna Dialogue tube amp of only 70 watts/ch and had no problem driving the Maggies. Note in Stereophiles' measurements of the Sphinx that it clipped at 150 watts/4 ohms, well below its claimed spec of 200 watts/ch. 

If you're considering Class D, best to go with one of the Hypex N-Core based units. Some of these newer amps are at least meeting claimed output and measuring well. N-Core is the latest development from the guy who wrote the proverbial book on class D topology.

As for Rogue, I owned a Cronus Magnum II and it sounded way more ballsy than the class-D hybrids. Aside from a high noise floor it was a great sounding amp.  Same for the Parasound Halo Integrated - way more grunt than the hybrid Rogue amps.

Another you should look at is the Monolith 2X.

 It was designed by ATI which is a very respected amplifier manufacturer, known better in the pro audio community. Audioholics measured this amp and it performed better than many at much higher prices. 

That Monolith 2X sounds very promising! In addition, aren't Adcom amps known for being (if nothing else) quite powerful and budget-friendly? 
...as the 'resident rogue Walsh fanatic' (DIY; definitely not Ohms....)....

If you've an existing 5.1/7.1 integrated amp or (horrors!) all-in-one...
(while you're comparing/weighing your options...)...you Might Consider...

2 pairs of the smaller Ohms...perhaps of the 'satellite series'...a matching sub of a 'sane' size, since it is a small(er) space....

(Ohm does have their return policy, so it's reasonably a 'safe trial' to do...)

...and listen to what happens. *s*

Ohms>Walsh>omni's: 360 deg. radiation.  If you'd like 'loud(er)", the best means to do so IMHO with any Walsh is to add 2 more if the space (and your taste) allows it...volume control of the 'back' pair is a plus.

At a low volume, subtly occurs.  Turn it up, and you may be able to flex sheetrock. ;)  They have this 'additive' quality. *G*

But, as noted...I'm just a extremist fan of the 'basic concept'...
Hahaha! "Bend sheetrock"... I had some Klipsch Chorus IIs that could do that. Just sold those to help finance this OHM excursion. And yeah, from what I've heard from Steve Guttenberg, the OHMS sound nice at higher volumes. 
*I myself am not a loud listener. I will occasionally turn things up, but not too often. 
I use a stack of Crowns (5kw total power)  to run my media room, 2 pair Klipsch Cornwalls, 2 Heresy,  1 Cornwall center, big VMPS sub. The Crowns sound amazing, very neutral, no noise, even with the efficient Klipsch, they are nigh indestructible,  and can vaporize listeners if I turn it to 11.  the Klipschorns in the listening room are on Rogue tube monoblocks but I think I could run Crown to them with little degradation.
Hmm i heard the Rogie Pharoah running Magnepans at my dealer and it sounded wonderful.  He carried full Audio Research and Rogue lines and liked the Pharoah best. 
@redstar....*G* Agreed...and I'm playing into a larger volume of space..16dx 21w x 12h(average)...and decidedly 'industrial'....

..and mine are more the DIY version of the HHR TLS-4's...slightly larger, not so 'pretty', But...I'm working on the latter....;)

(...and right now, 'the walls have ears'...so I don't want anyone to think I'm trying to sell shares in the Brooklyn Bridge or 'lake bottom property' ...but...)

Omni's in surround sound are definitely Different than typical driver systems. Even without 'surround enhancement' by the equipment, without 'adult beverages' or whatever your state (regional, not mental) allows....

Above average studio work on some recordings seems to have this marked tendency to 'place' instruments and occasionally performers into perceived locations that may not be noticed with 'normal' speakers.

Now, this may be induced by phase interaction/interference patterns of the waveforms they generate .  And,not to ignore the reflections off of walls, furnishings, and anything that exists within a given space.

I have plenty of those, as do most habitable spaces. *S*  In my near future, I intend to 'set up' in a new one that promises to have less of that, and  be decidedly 'clear(er)' of these 'early reflection elements'. *L*  So I hope to either dispel or enhance what my senses try to make sense of.

Anyway...I thought I might broach my experience with you, if only to hint at what an omni system might be if you really become not just a convert, but a fanatic.  There's not enough of 'us' around...

"Embrace the Force, Luke!"  *L*  It surrounds you, after all....;)

(As for those 'others' reading this....you can start throwing your 'bricks' now....;)..."Shields Up" *L*)

Just a couple of points....

If you do the math, the 2000's will need about around 24 watts for you to experience a sound level of 86db at a listening position about 10' back from the speakers...ok...now lets add some safety factor...say 6 db for peaks and you are at 100 watts....and nothing wrong with having more than 100 watts...more is safer than less.  If you listen louder than 86 db...then add more watts....if you listen lower...then still stick with 100.

Now, as to the Crowns....since a number of the guitar stores sell them with a 60 day return...you can try them easily.  Here is my impression of the XLS2000 which I owned for a while....powerful low end but not detailed....massive soundstage in width but zero depth....ever so slightly bright on the top end....slightly brighter in the midrange.....overall sound presentation is forward and not laid back.  Pretty good sound for under $500 but if you are willing to spend more, you can do a lot better, especially if detail and soundstage matter.

But, since it is so easy to try them and get something else....Nuprime, PS Audio, CherryAmp, VanAlstine....there are tons of choices (and you don't need to spend a ton)....and see what you think when you have them side by side.  Since almost everything is returnable these days, you can't really make a bad choice and no matter what any of us tell you...you can't really know without trying it in your system and listening the way you listen!!
I recently went from a SS class a/b amp (Odyssey Stratos upgraded to Kismet Reference) which died to a class D, Arion Audio S500 for my 2000s.  I couldn't be happier.

While I have great respect for John Strohbeen, I disagree with him on a few points.  Rather than place my 2000s close to the front walls, I pull them out into the room a bit.  I do run them with a pair of Vandy subs, though.  Also, while John likes to point out that his speakers sound good with low or mid to fi gear, and they do, IME, they will sound better with better gear.  Every upstream upgrade I have made has improved the sound of the ohms, and not in a subtle way.  So, go with the best amp you can afford now, but upgrade when you can.  I think you'll be glad you did.
@bondmanp your Odyssey died? Don't they have like, an insane warranty? BTW, I have heard nothing but rave reviews about Odyssey gear so I'm really surprised you prefer class D over the Odysseys! Was you Kismet not powerful enough for your 2000s? 
I have a set of Ohm 1000s that I run with a Bel Canto C5i. As mapman noted, this is 60 watts/channel, BUT that is at 8 ohms. The C5i doubles its power output at 4 ohms which is indicative of a very good power supply. My Ohms are 6 ohm nominal loads, which means I have about 90 watts available to power them. I'm not a headbanger in terms of volume.  I have a sound level meter and the mid-80 dB range is very loud for me. I have no problem reaching that level cleanly. I'm very happy with my system.

I use the c5i with my Ohm 100s. Our two setups are very similar then.

Other than absolute volume levels possible, it’s a very hard combo to beat. The sound reminds me a lot of eletrostatic speakers like Quad ESL but with better dynamics and the unique Ohm room filling soundstage and large sweet area of coverage.  Very much like the players are in your room. 

I listen to a lot of classical music as well as folk, americana, jazz and other forms of music that are heavily acoustic. I agree that this system is amazing in its ability to throw an image that seems like the players are there with you. Even more amazing to me is the ability to change positions and move around the room while listening and have that sonic image behave the same. Sadly, it doesn't fix bad recordings, but if it did that, it would be messing with the good ones, too.
@mlsstl , agreed.  Some recordings become almost 'holographic', and immersive....
Then there's the one's that still come off 'flat as a pancake' in contrast.
Back to back, it's like the air just got sucked out of the room...
One gets 'picky' after awhile. ;)
@redstarwraith... I think the warranty is 10 years. Life expectancy of the caps he uses is 12 years. But even if it was under warranty, my point was that I am no longer able to maneuver this 64 lb amp easily enough to pack and ship it. So, I am done with it. Too many catastrophic failures for me anyway. I desire reliable gear.

I think it was powerful enough for my 2000s, but I think the 500 watts of my Arion Audio amp is better. My room is in the upper range of the room size for the 2000s. But beyond wattage, the Arion amp sounds better. Cleaner, more neutral and just as dynamic and holographic as the Kismet.
Interesting Bond, glad you found something that fits you better. I have been wondering how the PS Audio Stellar class D amps would fare on the Ohms. I have not heard them, seem to get good comments though, and the price on them is very reasonable as well...
@bondmanp I understand. 
@frazeur1 The PS Audio M700s are definitely on my radar. Seems they come up for sale on Audiogon every now and again too. 
Post removed 
Excellent! Used, the PS Audio and Bel Canto both seem like bargains overall. Even new, neither one is a bad deal by any stretch! Have fun and enjoy the trip!
I ran my Ohm SSC-4900s with PS Audio M700s and they sounded great. There was enough head room to really push the Ohms.
The music room has a used pair of BEl Canto ref1000m amps  (the same as I use)  listed for a very good price.  Those PS audio amps cost a bit more but are newer.
HI @redstarwraith

I was replying to a post about the NYC 2019 audio show... specifally about Ohm demo room....

thought you might find it of interest... as they were demoing Super 2s ( Walsh 2 that been factory upgraded to current 2000 specs ).

---- from this thread
my reply. :

Ohm is a favorite of mine as well... There factory is around the block from my office...

I agree with what you said ( The OP ) below" This is where the Walsh's blew me away, they did have a Carver amp/pre as part of their rig, as the female voice is always a wonderful indicator of the true depth, capability, and beauty of a loud speaker."

What John and Evan was presenting at this show was a Retro system that has been upgraded to current standards....
So you saw what looked to be Walsh 2 but they were upgrades to Super 2's .... you can see them at Ohm website ....

The Carver rig you noticed has been gone thru by Nelion Audio .... check Greg's site too...
This is actually a Carver M-1.0t mkII opt002 Restore and Upgrade by Greg at Nelion Audio
with the following specs..

Power into 8 ohms:
Stock: 200 watts  
MKII OP002: 460 watts

Clipping into 8 ohms:
Stock: 350 watts
MKII OP002: 500 watts

Dynamic into 8 ohms:
Stock: 550 watts
MKII OP002: 700 watts

and the Carver Pre-Amp had the Carver C-1 Bill D Mod done by Greg at Nelion Audio..

The idea was vintage gear that was brought up to todays standards and people can get this level of sound for a reasonable amount of money....

I happen know this level of detail cause the Carver equipment is from one of my home systems ! and yes I have it hooked up to a pair of Super 2s and a TD-125MkII

Good Listening !

@bsohne...  I have said for a few years that John Strohbeen might be making a mistake by demoing his speakers at shows using only midfi gear.  Especially when he is showing more than one pair, I have been saying that better gear would result in a better show demo.  It seems he finally did that in New York.  And, surprise, it sounded great.  I hope he gets enough good feedback from this show to encourage him to show his speakers to their best advantage again in the future.
Zero doubt in my mind that my 5000's (and now Pro-3000's) highlight differences in equipment changes more so than many other speakers I've owned.  It's pretty remarkable.

One of the more recent speakers I have owned is the DynAudio Contour 60.

The OHM's far and away highlight equipment differences more than the Dyn's (and the dyn's did to an extent).

I like the OHM's a fair amount better.

I have another pair of speakers being built right now, but I won't let go of my 5000's before I really get a chance to put them head to head.  I've never done that before.  I usually sell when I decide to buy.

I will absolutely be keeping at least 1 set of my 5000's or 3000's.  

Personally I do hear differences in them, the voicing is quite similar as John states.  But the 5000's are better, no question.
I had a question regarding these Ohm (2000-3000) Talls.
If they need lots of power (low power tube amps are not recommended), do they should they need to be turned up loud (60%+) to sound good and clear? Or can you still her good detail when played at lower volumes, (20%-) with a big amp ? Thanks

My theory is JS smartly markets to the masses not the very limited high end audio market so he presents systems for modest cost that sound great. Since he sells speakers not amps, he keeps the amp costs down. 
I agree though at high end shows you want to show the best your product can do so larger amp investment is needed. But then again, keeping the combo price down especially the amp helps sell more speakers so there you go. Hard to argue from a business perspective.

Back in his Tech HiFi days, high end audio was relatively unknown. Most companies including Tech Hifi just tried to sell the best sounding products they could at prices many could afford.
I agree, mapman, and I understand John’s approach. But he could do both, showing people that his speakers will sound good with whatever they feed them, but they will reward upgrades with even better sound. You will not have to buy new speakers as you improve your system. Over 10 years with my 2000s is a case in point. I have upgraded almost everything in my system, and the 2000s  have benifitted from every upgrade. Especially at an audio show, where many will want to know the speakers’ full capabilities, this could be a way to get attention from the high end consumer and journalists. Based on what I read here about Ohm’s demo at the NY audio show, he may be trying just that.
@high-amp... No worries. My 2000s sound wonderful at background levels, even listening to lossey internet radio. Too good, actually, as I am often unable to continue what I am working on, and instead focus on the music. I often end up cranking the volume anyway because, well, you know, this amp goes to 11!
I am also interested in getting some Ohm Walsh speakers but I know so little about class D amplifiers that I need to do some listening.  After spending my entire life with A/B amps I thought I might just grab a Schiit Vidar or two until I can make a more informed choice.  Does anyone have any experience with Vidar(s) with the Ohms?
HI @bondmanp

I agree with you , that you want to show your product in its best possible light!   And I also understand where John is coming from ....  Like when he showed the Ohm 2000 two years ago at the NYC audio show ... He used an Outlaw RR 2160  ....  and was using " lamp cord" ....  and old oppo dvd for a cd player and a Node 2 ...

People in the audience asked " Hey is that lamp cord ? , he said yes ... "  The person then asked him ... " if we used better cords and interconnects, amps and sources ... what would happen?  John just said " It would sound better." 

John was showing sub 3k speakers and thought it would be odd to demo the 2000 with 10k dollars of amps, sources and interconnects...

That NYC show the total system was under 5k with speakers , amp  etc...  

It can only get better...

on another note..
my main room system I have a pair of Walsh 5 ( ca 1990 or so) that I had Ohm upgrade ...  John and Evan did a great job on the "upgrade" to Super Walsh 5 LE....

See his blog...https://ohmspeaker.com/news/how-big-is-a-big-room/
That is my living room , the one with the two dogs hiding in plain sight!
My wife does not let me play them loud... which is a shame as I have them hooked up to Carver Seven-7 Solid state monoblocks... 565 watts / channel...  room level... and its great !

Good Hunting
Bill Sohne

I have a variation of the same question. I love my restored Walsh 4’s and drive them with a Parasound Hint integrated amp. I wonder about the merit in adding a power amp and if so, if a new model or one from their era (e.g. Carver / Sunfire) would be a better match. I don’t want to spend or make room for something with minimal listening impact. Better to invest in upgrading to Walsh 4000?  Comments and recommendations welcome.
HI @johor72

I dont want to sound like an ad for https://nelionaudio.com/ ....   480w like that of one of Greg's upgraded M1.0t would do the trick....
he sells them already upgraded...   on his site.. .he sells out and then gets more in... or you can find one used and then send it to him for upgrade...  the trick is to find a non working one for cheap and then send it off to get it upgraded and modded and its get repaired in process ( no addition charge unless its a real basket  case... ).

but that is my opinion.bestbill
Not sure of your budget....but....here is an absolutely fantastic sounding amp...sort of a blend of tubes, class A and Class A/B....normally $1700 new but being offered for $1100...and maybe they will take less.  I own a CherryAmp and can't say enough good things.

  Redstarwraith, I was wondering if you could let me know the specific amp's John Strohbeen recommended? I also have a pair of 2000's and thinking I'm in need of a upgrade.
Oddtodd, in my conversation with John, I made it clear I could not afford something like a PassLabs amp, so I asked him to talk in terms of affordable gear. Like was mentioned above, he readily told me about driving the 2000s with the (very affordable) Outlaw receiver. I asked him how Ohms sound with Class D amps as a lot of them are affordable. He said they sound fine and told me a number of customers had success with Emotiva amps. I specifically mentioned Zeos' driving his with those Crown PA amps and John said, "Yeah, that's another way you could go." And I laughed and asked, "Yeah, but...I wonder how that SOUNDS?!" And he said, "We had something like that same set up for quite a while here in our shop. It sounded good!" 
As I have posted elsewhere, I recently replaced a broken Odyssey Audio Kismet Reference amp (A/B) with a class D amp from Arion Audio.  The Arion is actually smoother and cleaner than the Kismet, by a very noticeable amount.  The combo of the Arion S500 with my 2000s is wonderful, and the Ohms clearly showed the many differences between the two amps.  Bottom line, John's speakers will sound good with almost any amp of sufficient power, but ever better with better amps, including really good ones that cost more than the speakers.
Given how much I like the Pass Labs with mine, if I were on a budget I would look for a used BAT VK200.

They can be found in the 1k range, sometimes even less.  They sound very similar to Pass Labs IMO and would do a great job.
