that I completely fail to detect any of the sonic shortcomings that georgehifi claims exist on my amps due to traditional FET transistors, the switching frequency being too low and the filter used to remove this switching frequency being of poor quality."
This quote from one of georgehifi's previous posts is actually my words from a post that has since been deleted by a moderator for some unknown reason.
I was referring to georgehifi's frequent comments criticizing good class D amps, which I consider myself to be a user of, as all having sonic shortcomings due to using traditional slower FET transistors, the switching frequencies being too low and poor quality filters used to remove these signal carrier frequencies. My point being my total failure to detect any sonic shortcomings in any of my 3 good quality class D amps despite his persistent claims that these shortcomings exist.
Nevertheless, I believe the questions from your last post, directed at georgehifi, remain very relevant questions:
George what specific amp or amps are you referring to in regards to "sonic shortcomings"? Two or 3 examples will do if you could.
Also what amp or amps specifically are you comparing with to reach that conclusion? What were the shortcomings of those?
Are you comparing apples/apples in terms of cost?
What are your reference recordings used to make the assessment?
Just to be clear I’m asking what you have specifically heard, not what you deduce from other sources.
Being a technical guy, I’m sure you can appreciate the value of being specific and not making generalized statements based on a limited sample.
Georgehifi has consistently refused to answer all questions about his claims of sonic shortcomings in recent class D amps in general. He's failed to respond to requests to elaborate and be more specific on his claims of sonic shortcomings from myself, several others and now from yourself.
Based on georgehifi's numerous responding posts on many class D threads, it's fairly obvious to me that he has little to no experience actually listening to good quality class D amps.
I say this not only because his descriptions of what these claimed sonic shortcomings sound like are very vague but also on his obvious inability, and often just refusals to respond to requests, to be more specific in his descriptions of what these sonic shortcomings actually sound like.
Because of the above, the complete lack of supporting evidence of his claims from any source and my and others' complete failure to detect these sonic shortcomings in any of our good quality class D amps, I've reached the baffling conclusion that he's fabricated his claims of sonic shortcomings for some unknown reason.
Although he frequently states he'll buy class D amps once they are perfected, I now consider this an attempt to disguise his true prejudices against class D and possible ulterior motives for his statements, unsupported theories and comments.
