Negative feedback Amp=more faithful reproduction?

"Mapman, the question here is if NFB makes reproduction MORE faithful. Some answered that there is no faithful reproduction, which doesn't answer this question, while others stated they prefer sound of ZNFB which doesn't answer this question either. The truth is, that there is no SS amp (and very few tube amps) with zero feedback. SS amp by nature is a voltage source, and as such needs some form of negative feedback, at least for the output stage. The question is how much and that might depend on the load, your preference etc. It is undisputed fact, that even small amount of NFB widens bandwidth, lowers output impedance and reduces THD/IMD distortions. Does it make reproduction more faithful on average? I think it might. What sound you like has nothing to do with original question."

Kijanki, you seem to be the only one who understand the intent of my original post. Thank you for putting into words better than I.

I find it amusing some found my OP to be an attack on their equipment and taste in music, which was not my intent at all. If some of you were offended, sorry.

Dracule1, What I'm getting from this is that some amount of imperfection can sound to many people more natural. Difference between natural, pleasing and faithful is fluid. Article was very interesting and thank you for posting it. I would only disagree with notion that deep feedback has no negative effects if amplifier is stable and input limited to slew rates equivalent to 20kHz. In ideal world it might be true but bandwidth never ends at perfectly 20kHz (TT often go to 50kHz) while high gain amplifiers, including op-amps have, (in spite of compensation) tendency to ring when presented with capacitive loads (speaker). It is big temptation for designer when he can improve everything 10-fold just by introducing more gain. I know that top designers like Nelson Pass or Jeff Rowland don't take shortcuts and that's why I bought Rowland class D amp. I know that modules were designed and made by B&O but Jeff Rowland name is enough for me to get interested. Some amplifiers are very expensive but you get what you pay for (Brand name). My amazing Hyperion HPS-938 speakers were a bargain but company doesn't exist anymore (so it seems). Now I worry what to do if something happens to these exotic drivers since nobody else makes them. Next time I'll pay more.

The reference to Class D amps is interesting. Generally, they use a form of negative feedback for pulse width modulation type of amplification.

Edwyun, this particular design (Icepower) uses Nielsen Karsten multiple feedback. One feedback comes from modulator while the other is from the speaker output. Class D is relatively linear to start with, while output impedance is inherently low hence it doesn't require a lot of feedback. In addition it is only one stage (modulator) making for small signal delay - less chances of TIM. Early class D consisted of primitive sawtooth modulator while this resembles sigma-delta A/D converter's modulator. There is nothing wrong with class D (SACD,DSD are class D) but carrier frequencies are still too low (Mosfets are getting faster every year). For the money it is bargain IMHO.

Ed:
Pass does indeed up simpler circuits. His XA.5 and X.5 series apparently have but 2 gain stages. So, in that case would feedback be 'global' or 'local'?
Also, Pass amps I see the specs for are about 26db gain...which is on the low side for people accustomed to 30db PLUS gain.

If I could afford it, I'd get Pass amps for my panels....I see a pair of XA30.5s at Reno which would be perfect for a biamp setup! (another can of worms)

Other posts address feedback without ever defining if they are speaking to Global or Local. It makes a big difference...
