Stock Voyager GaN amp (350/600) Contrasted with my EVS1200 (600/1200)

Ric - you should know better.  The (good) Mad Scientist feet are underneath and a 25 pound weight on top.  I'm the one with the bad feet.  Any recommendation other than my orthotics and Hoka Bondi 7s?:)  OK - the rest of me doesn't look so great either:)

I will be posting more about what we listened on both amps to and perhaps more.  The EVS 1200 is going to a secondary system (Selah Audio SA-2s and a Rel Strata III sub) and I am waiting on a used Teac UD-503 (which I will use with a mini fanless PC and JRiver) as the Teac has volume control and an analog input (so I can have fun with my modded Carver C-9 Sonic Hologram Generator unit being fed by an Oppo 103D, which is connected to my network).  Canada Post is estimating delivery on October 27 as of right now.  In addition, since my friend comes over most weeks, I've been helping him with recommendations for his system.  At one point quite a while back, I brought over my Teac UD-501 (which I don't own any longer) to compare to his Schiit Audio Multibit DAC.  He got rid of that his separate Schitt Audio headphone amp and bought a used Teac UD-503 (which he indicated smoked his old stuff and I made some cables for him to get rid of his Blue Jeans ones someone recommended to him) and now has an Apollon Audio IcePower amp in a shallow depth case (which he needed).  So this will also allow him to hear things on similar electronics as he will likely be eventually building speakers with the help of a friend of his.

Note that I'm only posting in this thread (vs. the others) and observation between the two amps.  As some of you aware, there may be an uneducated individual (or perhaps more than one) who just don't want to understand that Class D now is not the same as it was a few years ago.  There are those that have had relatioships in the audio industry who just want to protect those who may be selling things at retail which may cost (e.g 2-4 times) more vs. commenting from actual experience of using the product (and one really can't comment on what another hears or does not hear - well I guess one can comment but in some cases we know why).

I have also discussed with Tweak1 about potential bringing down the modded Voyager (he's a hair more than 2.5 hours south of me) after he gets and breaks in new speakers.  As with any evaluation of sound in one's system, the user will generally select recordings of their choosing (my friend who came over last night and wanted one additional song added to the list I made up last week which he was fine with) which they are familiar with in order to evaluate the system.  Some feel the need to comment on the music selection as if it is a diner meny and they can order what they want.  For those and for those that fit in that category or of the prior paragraph, you may have a future as a back seat driver.  Please visit indeed dot com and best of luck with the job search:)

Anyway - this is to follow-up a bit more.  Got too much to do to get to a video (I'm so far behind on listening to music I bought and I bought two more downloads today and won't get to them for a bit as I have a USB cable on the way as part of a tour and I'll just have a week with that) and it's not quite Halloween so we wouldn't want to scare that many people.  The modded Voyager is clearly better vs. the EVS 1200.  The only thing I would have done if I had the mod done is leave the switch in and that's just my personal situation with having an integrated AV system.  The Voyage has better soundstaging, tonality, bass, etc. On some of the recordings I heard things that were less present on the EVS.

The playlist used (we later listened to other things one the Voyager) was as follows (PCM recording were all in FLAC and anyone is free to look up the reccording chain to their satisfaction - one of the cuts was from one of my favorite record labels - Sound Liasons - https://www.soundliaison.com/index.php  and the cut used can be seen here - https://www.youtube.com/watch?v=Kf_S2l3Y_lM).

The first two were used on Jay's comparisons and to get a bit of a frame of reference vs. his descriptions of the difference between the Rouge audio amp and his mystery 200W Class A monoblocks.  The next two involved artists I've seen live in my favorite small club (which is now out of business - https://www.arlnow.com/2017/09/08/breaking-iota-club-closing-this-month/).  I've listened to those cuts many times (as with most of the rest of them) and can be seen here - https://www.youtube.com/watch?v=dqu9MSfBPN8   and here - https://www.youtube.com/watch?v=Lby_GXOrNLU    since many probably have not heard those).  Tin Pan Alley is of course live.

On the Vanadeer cut for example, there was greater definition in the soundstage where the singers were standing (vs. what I heard before).  All in all it's a keeper for me and some of the more traditional (but now the ultra high end as in Jay's system) high end brands which cost more money are in for great competition for those interested in doing the comparison (vs. a brag factor that what they have costs more).

Very cool review. Eventually I will get a modded V, but Im very happy with the stock one, especially once I lifted the chassis off the rubber feet with Nobsound springs and took the top off. It would still likely benefit from some damping material. Also, I would like to hear the stock V with the 2.8s as I am quite familiar with it


2.8s: Slight delay (I hope) to finally getting the 2.8s: quite possibly next week. For those who may not know, they are still at CDC warehouse in Miami after the truck they were shipped in was found to have BARRELS OF toxic illegal drug chemicals (the truck driver is doing time). This was just before the lock downs and January 6th, which had the CDC guy in charge quite busy

cascadesphil,
How about midrange and HF clarity, speed, transparency from the modded Voyager vs EVS 1200 (approximately a modded Rouge Studio N10-DM)?

I am in touch with Rouge.  The Pascal modules are claimed to be superior to IceEdge for clarity/neutrality.  My Mytek Brooklyn Amp original version uses modified lower power Pascal modules.  The Mytek is a sharper, leaner sound than the Studio IceEdge Rouge, which is still neutral but fuller in bass with full dynamics, as Jay had found.  The upcoming Pascal MPRO2 module is stable to 2 ohms.  The available MPRO2 has the highest clarity with analytical quality, but it is designed for speakers with minimum load of 4 ohms.

All those things are better on the modded Voyager.  It is just in another league.  My friend thought I was crazy when I told him I'm buying it as my system sounded so good.  Keeping the EVS though.  Now in a secondary system.  At some point (waiting on roofing issues), the main system will be apart for a bit until painting gets done and I'll be using the secondary system as my main audio system for a bit.

I don't know how the Rouge sounds (or what they use for everything internally).  All I can say is I had a Mivera SE, (with the one half inch thick front and rear panels which were not made throughout the run of SE amps and he stopped making those) and everything possible upgraded, including two Synergistic Research Blue fuses (I added later) and the EVS was in a totally different league.  Others heard it as well over my place.  The (modded) Voyager is yet in another league.

I broke the EVS in using a secondary system (and for a drop before I got the EVS I tried the Mivera in there and the Mivera was in that system for well over a year and I sold the Mivera a bit over a month ago) and the Mivera which imaged nicely, sounded flat vs. the EVS.  So while I haven't heard the Rouge, which obviously did well in Jay's comparison (was it something like 43% thought it was better?  And yes I understand the internet can't capture what is in the room), I'd think the EVS would have done better as besides upgrades to the internals, the modules themselves were modded (by the mad professor).  There are others that Ric sold the amp to and compared it to the stock Mivera (I believe one of Ric's customers had a couple of Mivera amps and used them in mono to compare the to EVS).

Yyz, who sold me the modded Voyager informed me  he offered it to Jay and I'm not sure how much time elapsed, but when I bought it I don't believe Jay got back to him.  It was also noted in Jay's thread (by ricevs on October 7)  " What would be really cool is if Phil would bring over his EVS1200 and the modded Voyager he is about to receive to Jay’s place and they could do a four way shoot out with the stock Rouge and the Block Monos (make sure you use good footers under the class D amps....not the stock feet). You could do this in a few hours and then make a video where you both comment on the differences.....none of this silly 3 minute song A/Bs of unknown amps please. Just tell us what you hear. We trust you. You could then play a minute or two of the best of the three versus the Block....for reference. This would be very informational for many."  I also noted on that day (in Jay's thread) " So as far as any shootouts that Jay wants to do, that is up to Jay."  I'd guess I'm under 3 hours from Jay (and noted that)

So I guess we'll really never know the answer.  I appreciated what Jay did.  What it showed to me is that the Rouge performed very well and how much additional money got things to another level.  Jay also noted that everything before the amps contributed to the sound and it is the same in my place.  I use a Lumin U1 music server and an EMM Labs DAC 2X (version 2) along with a Modwright LS36.5DM.  I currently have the EVS in a system with a Sherbourn Pre-1 and a Teac UD-503 DAC.  Those just aren't in the same league as what is in the main system.
