Bruno Strikes Again. Purifi 1ET7040SA VTV Amplifier.

He wouldn't be here if he wasn't.

If you want an amp that doesn't have a sound, which is Bruno's design goal, then letting someone add distortion and noise that they find appealing may not suit your goals.

Listen to the interview with Bruno. He's not prone to making faith based, unsupported claims. He's at the forefront of class d design and his work is based on solid engineering and science, not voodoo.

Rouge (Italy, not Rogue) also has the modules.  No doubt a built amp will be forthcoming from them too.

Hope Purifi or Neurochrome make input boards as well for this new module. Not sure I have a lot of faith in VTV after seeing some the internals of their assembled amps.

Look forward to seeing and hearing what Rouge Audio Designs brings to the table.

Pink doughnuts. 

@yyzsantabarbara Have you tried Cherry Amps? I have heard them (not sure which one but I know it was a newer model) on some JTR speakers and the bass was insane without the amp even hinting at trying. I've truly never heard bass like that outside of an outdoor concert venue. I believe we hit 116 dB and had plenty more if it didn't make me almost ill it was so strong.
