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

The new AGD stereo amp is encased in a Single billet CNC-machined cabinet, which does cost a bit of $, but in my experience, benefits in SQ by lowering the electrical and mechanical noises to the amp's electronics by a considerable margin. As much as I have dampened amp chassis's ( as does ricevs ) for 50 + yrs, I cannot claim it would be the equal of a single billet cnc-machined cabinet, if it were available. This is how important I find, of the minimization / elimination of vibration, resonance and chassis tuning.

mrdecibel,
How did you test this?  Did you mount the same circuit boards in a super damped chassis and then inside a single billet chassis?   Did you damp the circuit board and the standoffs in both cases?  Did you try copper plate underneath the circuit boards.......so the standoff are on copper instead of aluminum?  In my EVS1200 amp I used a thin sheet of soft copper underneath the IceEdge modules and then under that a quarter inch aluminum plate and then the aluminum chassis under that.....also the IceEdge has its own aluminum heatsink above the copper.  Thick copper sheet did not sound as good.  Aluminum by itself rings (billet would ring less but its still there).  Magico went through a lot to use less and less aluminum and damp the heck out of it when they use it.

Lot's of things make for great sound.  Don't think having a Billet chassis is that important in the grand scheme of things.  Every single thing you do makes a difference.  Do the things that make the most difference first and then mess with the subtle things.......I do some damping to the chassis on the Voyager.....it helps.

These three pics on this page show the inside of the Legacy I.V4 amp.....same as V2 except 4 modules. You can clearly see from these pics that these are completely stock stereo IceEdge modules using just one channel of each one (hence used as mono blocks). One of the three pics on that page shows the brackets holding the modules up and the ground wire from each one. Nothing but ordinary here.

Please provide more information about the power supplies which can play a major factor in sound quality. What can you tell us about that?

"At least it is WORDS from someone who listened."

Please tell us about your listening impressions of the i.V2 or 4 Ultra? Did you do this audition in your home system? Which other amplifiers did you compare the Legacy to?

I never listened to the Legacy amps with bone stock IceEdge modules.  I made a dozen amps with those modules and spent months modding the modules and the chassis and cables before releasing them.  What I did is far, far superior to a stock module in a box (I did one mod at a time and each mod made the amp better).  Now the Voyager is found to be better by two people than my tweaked out IceEdge.  What Legacy did for $4700 you can get the same thing delivered from Rouge Audio Design for $1600.......I can then mod it to make it better......but it will not be as good as the Voyager (stock or with my mods).  The power supplies in the IceEdge modules are beefy.....very good.  I do modify them for better sound.
