Review: Magnepan 3.6R Speaker

Category: Speakers

I started this audiophile thing when I was 12, at which time I drooled over mail-order catalogs from Allied Electronics, Heathkit, and Lafayette. Haven't been able to kill the audio bug yet, nor do I plan to. My first serious system consisted of mid-80s Nakamichi gear, including a 3-head cassette deck. I also had ADS towers and later a Denon 3000 CD player after I wore out my NAK unit.

Some people just don't get it--this audio obsession, that is. For me, a system is not about techy cuteness, kidney-assaulting bass, or surround-sound special effects. I'm not quite converted to super audio CD yet, either. Not that it doesn't sound good; it's just that it's still too expensive to do both super-audio and "redbook" CD well. That brings us to my present system, which does ONE thing and one thing WELL: play CDs with a jaw-dropping realism that continues to bring tears to my eyes and goosebumps to my skin. THAT, my friend, is what we shell out the precious green stuff for, is it not? (Which means that for FM listening, I'll most likely do the newest Bose-killer Cambridge Soundworks table radio. For now, my system is sans-preamp, with the CD running direct to the PS Audio HCA-2 via variable outs, which sounds spectacular! Who needs bells and whistles?)

After auditioning a plethora of contenders for best bang-for-the-buck speakers out there, I was immediately addicted to the Magnepans. The 1.6QR (for Quasi-Ribbon) is quite fine, and probably the best deal going for under $3000. But once you hear the TRUE ribbon of the 3.6R, mated as it is to the most harmonically accurate, transparent, and life-sized musical image I have experienced at ANY price, there's just no going back to anything else.

I listen to just about every kind of music there is--short of rap, country western, and thrash metal. For me, it's all about conjuring up the reality of a live musical event, and doing so with finesse. If pressed on the issue, I would have to say that classical music, jazz, and celtic are my three favorite genres for listening. First, a word to the wise: give the Maggies a long leash, and don't make any judgments on them 'til they're given the mandatory 400 hours of break-in time. (That was no sweat for me, having put the components together over a several-month period as budget allowed.)

Time does not allow me to discuss all the discs I first audioned this system with, but here are a few: Entangled Devotions (Beethoven piano concerto #5 and Moonlight Sonata), Pope Music gold CD; Jazz at the Pawnshop double-disc set, XRCD; Dianna Krall: Love Scenes, CD; and Rimsky-Korsakov: Scheherezade, XRCD. Like many audiophiles, the reproduction of upright bass and grand piano were THE winning factor of the Magnepans. Non-audiophile friends, who at first questioned the sanity of spending the equivalent sum of a nearly-new Honda Civic on a MUSIC system, are starry-eyed in amazement of these speakers, as grand piano, orchestra, and vocalists are virtually transported into my humble abode. (Much credit goes to various high-end consultants, who brought such amazing synergy to the various componentry involved here. EVERYTHING about this system is a match made in heaven.)

There are many great speakers available, each excelling at one or two audiophile feats. But none match the coherence, imaging, immediacy, and sheer musical involvement of the Magnepans. Quads are great if you can get past the Peterbilt radiator look--though they, in my opinion, simply cannot match the Magnepans for harmonic, tactile presence and authority. (No questioning their crystalline clarity, but SUBSTANCE is missing.) Martin-Logans were a MAJOR disappointment in this regard. I actually preferred the sound of the JM Labs to them. But even the Thiels, my long-term reference for dynamic systems, left me wanting after first hearing the Magnepan 3.6R.

Now that I've had many, many long hours with these speakers, I am more in love with them than ever. The above-mentioned discs played through these speakers continue to wow everyone who I have allowed into my sacred listening chamber. The amazing harmonic integrity of the Magnepans is so compelling that I am seriously considering foregoing a planned subwoofer purchase. I can't stand boomy bass any more than an emaciated midrange or spitty, reedy highs.

My old mid-eighties ADS towers served me well, and became my reference for "box" systems until I heard Thiels, which, as I say, cannot hold a candle to the Magnepans. A comparison to my old ADS towers would be a waste of time, as good as the ADS speakers were. In conclusion, I have never heard vocals--particulary female vocals--reproduced with such uncanny realism. Nor have I heard large-scale orchestral works or intimate classical or jazz ensembles made to sound as convincingly three-dimensional and LIVE!

I can find no fault with these speakers. The only thing I would change if the laws of physics allowed would be their room-dominating stature. (I really have no problem with their looks. I think they're gorgeous, especially in their deep cherry with black grilles. But then again, I don't have the spousal-acceptance-factor to deal with--yet.)
Would I "upgrade" to anything else if cost were no object? Perhaps, but then only to the MG20.1R, which a friend owns, along with Mark Levinson componentry. And, dare I say, my system isn't all that far behind his in terms of genuine musical enjoyment.

Which Thiels did you own? I loved my Maggie MG IIIa speakers, but I traded them in on the Thiel CS 3.6 because of room placement issues at the time. I haven't heard the MG3.6R, but I've heard they're excellent. I powered my old Maggies with a Levinson No.27. Classical and jazz were awesome with the Maggies, but the Thiels do more justice to cranking rock 'n roll. They also deliver deep tight bass that was lacking in the Maggies. Even in a large room. Nothing can beat the speed and pinpoint accuracy of the ribbon tweeter.
Dbdeeb, I agree with your complete assement of the 3.6R's. This is truly a great speaker in every aspect of sound there is. I will never sell mine because every time I listen to this great classic speaker, I just think there $4500 but they should be $10,000 or more. I like the looks of the speaker also even though it is a big speaker. I use mine with a subwoofer and I like what it does to the bottom end and makes the 3.6's sound even more revealing sounding on the midrange and highs. It also makes the speaker sound more dynamic in all regards. You just can't get any speaker any better than this one at any price. Best steal in audio bar none!!!! Happy Listening Steve
Hi, does that "jaw dropping realism" include playing all types of music at realistic levels, or is it limited to polite music at realistic levels or dynamic music at polite levels? How about Rock, can that be played anywhere near "realistic levels"? Hope you bought yours new.
Recommended upgrades for the 3.6's are the Mye Audio stands, and jumpers from Infinity Audio.
The Mye Audio stands tighten everything up, images and instruments take on greater clarity and substance.
They are very well built, come shipped in wooden boxes, and include solid adjustable brass spikes.

Trying to make the 3.6's move back and forth with these stands are impossible! Man, what a difference in rigidity!

The Infinity Audio jumpers also make a nice difference in clarity. They can be terminated with Cardas Maggy pins, which work excellent.
You can get solid silver, or silver plated copper.
These jumpers seemed to clean up the top end a bit, more extended and cleaner.

I am sure many of you know about these tweeks for the 3.6's, but for those who didn't, now you do!

Happy listening.

Best, Bill M.
Hey Billm (or anyone else that uses the 3.6's), where did you buy the Infinity Audio Jumpers? I haven't been able to find any place that sells them via google. I have found some Cardas Golden jumpers made specifically for the Maggies...have you compared these at all?

I'm a happy owner of Sound Lab full-range U-2 ESLs (same size as the A-3s and M-3s, don't even ask), but I did some careful listening to the 3.6R at a local dealer. The mid-range is startling in its clarity and immediacy. I definitely heard some things I hadn't heard on the U-2s, but . . . there's no way I'd make the trade. The Maggies do a few things that the U-2s don't do -- they project peformers and instruments larger than life-size, and they train an electron microscope on the sound. These are not necessarily good things -- I was a bit nervous being in the room with a 10-foot-tall tenor saxophone. The Maggies also don't do a few things that the U-2s do -- they don't give you the bottom end that makes music sound like music, and they truncate the notes before the decay is actually done, er, decaying. Your actual mileage may vary.
Greetings to all.
I found another tweak for the Magnepans:

IsoClean fuses. Here is a link:

Very nice, but perhaps a bit pricey @ $25 each.

I actually use a slightly larger value than what Magnepan recommends.

These fuses were shown at the last CES.

I also use these in my VAC 220 monoblocks.

Things get more dimensional, and cleaner, clearer, especially in the mids. Not much mind you, but enough to make a difference in a high resolution system.

There is a good dealer in CA that sells them, and I know he has a full stock of fuse values as of: [4-1-05].

While I am mentioning fuses, Xindak makes some excellent silver fuses(the IsoClean are not silver), but they are shorties, not the longer mm version. I like these ALOT, big difference in a high resolution system.
Here is a link:

I have another tweak coming for the Maggies, albeit a bit more pricey, more to follow in a few months.(crossover mods while keeping the external box stock, etc.)

I am well aware of all the killer mods for the Magnepan speakers, but I like to mention stock mods, or tweaks that do not change the basic panels, internal wiring, outboard crossover box, etc...

You can always find more in depth mods for these speakers using a Google search.

I also use the Infinity Audio jumpers on my 3.6's and they not only cleaned up the top end but also improved the bass and overall dynamics as well.

By the way Bill, what size and value of ISOCLEAN fuses did you use for your 3.6's? That sounds like a tweak I'd love to try on mine.

The Isofuses I use are the same size/length that the holders will fit. Regarding the value, I use 1 amp higher on the treble, and 1 amp higher on the mids, than what Magnepan recommends.[or is stated on the panels]

The fused protection is there pretty much to protect from amplifier clipping, for the most part. I use huge/powerful tube mono's in the winter, and powerful[600 watt/8 ohms] solid state mono's in the summer, hence no fear of clipping, for the most part.

Most tweakers will simply by-pass the tweeters all together, but again, I like to keep things stock.......

Another nice upgrade, although expensive, and what I currently use to augment the bottom end, is a pair of Martin Logan servo sub woofers. The Depth and Decent subs from ML match very well with the 3.6R's, not perfect, but REALLY close. Its all about keeping the crossover value low, have the right setting for phase, and keep the volume on the subs low.
And of course positioning in the listening room. [a biggie]

I use 30Hz on the subs, and the volume low. 35Hz will work also, but in my room, which is dedicated and treated with ASC traps, RPG diffusers, etc., the extra 5Hz can be a bit much on certain music.
I pretty much listen to everything, so 30Hz seems pretty transparent to me. It may seem like a waste,[$$$ wise] but it does add dynamics and a better sense of low end impact, along with a slightly bigger perceived soundstage.
If you have the scratch, a set of Depth or Decents will really make a killer addition to any set of Maggies, IMHO.

Back to the fuses:
One thing those Isofuses did for me was seem to add a bit of analog smoothness to the mids, and remove a bit of treble grit. Bass seemd about the same, perhaps a tad more organic, everything seemed to gel better, sonically.

This was all very slight mind you, and probably is only worthwhile on a high resolution rig, but I think anyone with a decent system with good ears [and an open mind] using Maggies would appreciate what they can do.

Another nice tweak is cleaning all the contacts, and there sure are a few on the Maggies!, with a Caig cleaner, or any audiphile approved cleaner. After you clean everything, remove the cleaner, and add you favorite contact treatment.
I use a silver contact treatment sold on Audiogon, its pretty good, and up there with the Walker Audio silver treatment, but cheaper.

Also, I am awaiting the return of my stock outboard crossovers. They were sent out to a long time/well established audio modification company for parts upgrades.

I will report on the cost [should be around $500-$750 or so], the parts changed, and the sonic effects of the upgrades.
The outboard crossover enclosures will be kept entirely stock.
Will report back in the next month or so, in the meantime:

Happy listening!

What do you think about magneplanar 3.3r? Can they be modded by anyone near Philadelphia?
Hi Shopsmartjazz.

I am not sure about anyone who can perform mods to the 3.3R's in Philidelphia.
Have you thought about upgrading to the 3.6R's?

It depends on the mods that you want done. Almost any established/well known modification company will upgrade the crossovers for you.

Try a Google search, you can also find info on some of the Maggie support groups, I know of at least one.

Also wanted to mention in my last post above, that folks by-pass the FUSES, not the tweeters, as I mistakenly wrote above.

I hope you find the support you are looking for!
