What is wrong with negative feedback?

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?

Negative feedback falls into the same category as damping factor both which alot of people dont understand including myself to a point,my counterpoint amp has a damping factor of i think 70 while the great or my bias is NOT GREAT digital amps go on and on about the high amounts of damping factor they trump on their stats.,My Counterpoint has plenty of bass ,it just has to be on the recording in the first place.

Roxy Ah lets make this simple,feedback is touted as bad correct? Got that?
High damping factor is touted as good. correct?
What i said was these figures are often misunderstood.Meaning that they can be irrelevant to the actual sound of a component,IE low feedback or no feedback doesn't have to equal good sound,High damping doesn't have to equal better sound either,its the final sound that counts.
