Ok, let me clarify then: I cannot hear 500kHz, not only because of my hearing apparatus (at my age I have difficulty hearing 15kHz), but also because tweeter’s output drops like a rock with combined effect of membrane inertia and increasing tweeter’s impedance (easy enough to check tweeter’s frequency response chart). There might be intermodulation products, but only if tweeter’s membrane can move at 500kHz - no chance . In addition output filter, set to about 1/10 of the switching frequency, is at least two pole resulting in >40dB/decade suppression. 500kHz frequency that I cannot hear and tweeter cannot response to is already suppressed by >40dB from the peak loudness. I challenge anybody to detect, form the seating position, when my amplifier is on.
Class D Technology
So I get the obvious strengths of Class D. Efficiency, power output & running cool which allows for small form factors. I also understand the weaknesses somewhat. 1. Non-linear & lots of distortion that needs to be cleaned up with an output filter.
So my question is, if it weren't for efficiency & power, would there be any reason to own a Class D amp? Do they beat Class A in any other categories that count for sound quality?
