Hello Karl,
I have no problem with individuals criticizing any amp or amp type if it's based on personal experience. I was hearing the same accolades and criticisms repeatedly of class D amps about 10 years ago on Audiogon forums and was curious about class D but didn't know who to believe.
Most of the accolades were coming from those that had dared to try a class D amp in their system But I had a hunch that many of those repeating common criticisms of class D performance had never even heard a good class D amp in their systems or any system.
So, I just bought a Class D Audio SDS-440-CS amp with a 28-day free in-home trial period for about $600 and decided to find out for myself if class D was any good. That was 10 yrs ago when I used all good quality class AB amps(Aragon, Adcom and McCormack) in my combo music and HT system.
The results of my personal experience comparing good class D amp performance with good class AB amps in my system and room are best summed up by the fact that I now utilize all class D amps, from three different companies (Class D Audio, Emerald Physics and D-Sonic) in my combo system.
The main intent of my comments to you are not to bash you for bashing class D, although I believe you deserve some bashing for bashing class D without any personal listening experience with it, but to suggest you would probably enjoy their performance and other characteristics in your own system.
But I do appreciate the reasonableness of your post and your intention to try to audition a good class D amp. I think you'll be pleasantly surprised.
Thank you,
Tim
