Please don't treat my occasional post questions directed to you, and your vast amp design knowledge and experience, as anything even remotely close to an attempt at rushing your class D amp design and development efforts. Of course, I understand you're going to take whatever time you deem necessary at every progression in the nuts and bolts process of creating a high quality class D amp that bears your company's well respected name.
My layman aim remains the same, which is just to seek out and utilize high quality system components that maximizes my music and HT listening experiences. Having subject matter experts, such as yourself, explain things to me in an easily understood, relatable manner while educating my posterior along the way just happens to be a much appreciated bonus. Thank you.
For example, your concern about excessive damping factors on class D amps is something I can relate to due to experiencing its effects on my system's performance. I've previously driven a pair of Magnepan 2.7QR speakers in my system with three different brands/models of high powered and high damping factor class D amps, two stereo units and a pair of mono-blocks. It was immediately very apparent to me with all three that the bass response was more prominent than with any of the numerous non-class D amps I'd previously used on these same speakers.
At the time, I considered this very powerful, taut, dynamic and prominent bass response the best I'd ever experienced on the 2.7QRs, that are 3-ways with a rather large 623 square inch dipole planar-magnetic bass panel section on each speaker. However, I subsequently purchased an Audio Kinesis Debra 4-sub distributed bass array system with all four subs powered by a 1K watt class AB amp/control unit. I continued to drive the 2.7QRs full-range (down to their rated bass extension of 35 Hz +/- 3db) with the class D amps and the 4-sub bass system was restricted to reproducing only the bass content from 20-40 Hz.
The bass with this setup was definitely improved in power, detail, dynamics and especially realism and naturalness. Over time and in retrospect, I slowly became aware that while I really enjoyed the bass response solely reproduced by the class D amps and the 2.7QRs, the bass sounded much better with the AK Debra system included. My theory is that the very high damping factors unique to class D amps was truncating the decay times of the bass notes. The four Debra subs, being powered by a class AB amp that has a lower damping factor and did not shorten the decay times of bass notes, therefore allowing the bass to sound more realistic, detailed and natural. Does this make sense to you?
Thanks,
