LSA Voyager GAN 350 versus Merrill Audio Element Amps or AGD Grand Vivace and Vivace Amps


The Underwood HiFi website compares the Voyager to far more expensive Class D amps costing $32,000 to $7,500 - presumably Merrill Audio Element Amps and AGD Vivace and Grand Vivace amps.  Has anyone directly AB'ed the Voyager amp to any of the Merrill Audio Element amps or AGD Grand Vivace or Vivace amps in a system with which they are familiar?

Hifinews had a report for AGD gran vivace couple weeks ago. I do found that the lab report numbers doesn't seem to be good, but personally haven't had the chance to hear it yet.
yyz, I forget was your mod from Ric or from Underwood?


FYI: Today's Underwood sale email has special price on a stock Voyager and their moded version. I have no idea how it compares to Rics mods
@tweak1 My mod was from Ric at EVS. I did not get the mod from UnderwoodHiFi. In fact, they did not offer a mod when I purchased the amp. I think the thread on A'gon may have spurred UnderwoodHiFi to offer the wiring upgrade.

The mod from EVS is much more dramatic. He even removes the power switch. An excellent mod.
@soundhound  I believe it's the AGD Audion model that starts at $7500.

@verdantaudio  I too am very intrigued by the Audions.  And I believe that now, too, Atmasphere's beta-stage class D monoblocks are also proprietary/purpose-built.

Soundhound, you covered the moving parts of the matter rather well, in my view.

The words “current” and “currently” are meaningful, however, as more and more choices will come, beyond what we already know is on the horizon: Atma-sphere, Mytek class D’s.

And as forum member, ricevs, and perhaps others have posted in some detail, the new offerings will offer advancements in design and sound quality. I can’t wait to see how manufacturers up the ante in performance and value to gain our business.

With respect to diminishing returns, I get that once you hear a difference you really dig, you can’t un-hear it.  So, to the the extent that it is within your means, you decide if you want to pay up for the delta. Or…look at other ways to get a meaningful delta in one’s system—which includes the seat and room.
