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.
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?
