Re: Don't be too hash to him.

"You said Sharp sounds good, IMO, via digital input saving the A-D convertion error. Considering its USD4,500 vs its lowly 2x50W, it better sounds good. Or who would buy it."

Actually he SX-100 was something closer to $20k when new so yes for the money it had better sound very good!

"All class D switch mode amps NEED
feedback loops to maintain the various proper functions of the amp, e.g. switch controller for the switching amp.

Through loop feedbacks, it controls & keeps the output duty cycle
from 5% to max 95% per the error voltage input, & safeguard the switching amp from blowing by monitoring the current sense I/P."

Are you saying then that this Panasonic he is going on about must have loop feedback and that Dan is wrong that it is no feedback? I am curious because my understanding was that feedback was a simple fact of life to make Class D work properly.
