How to evaluate amps that are not broken in?

OK, that's encouraging, Musicslug. I realize this is very much a newbie question, so I appreciate your taking the time to respond.

Robr45, I experienced a dramatic change with my Creek 5350 se-- far beyond what I was expecting, actually. So I guess that experience puts me firmly in the "believer" camp. Rleff, I will do as you suggest. Thanks!

Whoaru99, I couldn't comment-- I haven't owned enough new gear to have formed a strong opinion.

Well, I have to admit that I'm totally confused at this point. All of this disagreement re: breaking-in would seem insignificant if it weren't for the fact that audio gear is so expensive. Perhaps the safest route is simply to only purchase used gear, so the breaking in factor is a moot point.

Wow! Seems this thread has now entered the realm of philosophy! Naturally, the following question arises:
If a component goes through a break-in process but audiophiles are too busy debating whether break-in is "real" to pay attention... then what??????

Dcstep, I've been told that Alan Yun, Silverline audio speaker designer, particularly recommended Belles ... at least until he began building his own amps! My dealer is just now starting to carry Belles (I will be his first Belles buyer) and was unable to get hold of a burned-in demo unit. I will keep what you suggest re: low bass in mind.
