D amps

@hgeifman   they lacked the subtly, feeling, resolution, sparkle, air and imaging of my MusicalFidelity class AB amps that replaced them.

Thanks for sharing your experience with Hypex. I’ve been curious about it for a while. People say Purifi sounds better, but I doubt it will be a complete overhaul that fixes all these undesirable aspects. You might want to try the Topping LA90 and/or B100 that just came out. What impresses me most is the frequency-independent THD, something I haven’t seen from any other amplifier, regardless of what class they’re built from.

@hgeifman May I know which specific vendor's Hypex-based amp you or your friends have purchased from?  Knowing the specific Hypex-based amp vendor might be necessary, as different vendors often implement subtle design choices that can influence sound quality beyond pure measurements. Brands like Apollon, Nord, and VTV Amplifier are some well-known names offering Hypex or Purifi modules, each with a slightly different approach to things like power supply and housing design, which can impact the listening experience.
