I am not talking about the kind you get as a flaky seller, but as used in amplifier design. It just seems to me that a lot of amp designs advertise "zero negative feedback" as a selling point.
As I understand, NFB is a loop taken from the amplifier output and fed back into the input to keep the amp stable. This sounds like it should be a good thing. So what are the negative trade-offs involved, if any?
Kijanki, I could be wrong about this, and perhaps it doesn't matter, but, I don't think Ar_t 's amps were ice amps. Have the TacT amps changed since then?
A few years ago, we had a regular and good contributor (be nice if he came back) Ar t an amp designer, suggested that in his typical ss designs he would try to keep NF to a minimum, but in his switching amps though there was much more NF, it didn't seem to be an issue. I wonder if it was due to the NF in the switching amps occurring at a faster rate?
