First of all thanks for the answer.
I'm writing in english because in the italian forum nobody has listened both this amps.
My decision is now between the A500 and the 1500(or the new EP2000, that is the same with an additional tecnology)
this because the 2500 is a classH while A500 and 1500 classAB(of course better)
For the power I agree with you, but in Behringer main site the A500 seems to be that with the cleanest sound, and if you do a ratio $/watts the A500 has a bigger price-per-watt.... you know, usually this means more quality
anyway I said "usually"
So for you 1500 is qualitatively better??
It's for an home tehater so my only interest is that
and last but not least the bass reproduction is the same?
again, sorry for english
bye
