Some say that in the world as it stands at the end of 2011, if both are properly set up, a $10k Pass amp will be markedly lower in fidelity than a $2k A/V receiver. Why? The latter will have sophisticated and useful room correction processing, such as Audyssey MultEQ XT32. Considering this is the JBL forum we're talking about fairly efficient speakers. A 96dB/W/m speaker (like my 12" Tannoys) doesn't need a kilowatt in a domestic living room. 100W is more than enough.
This post was edited as it poses a good question, but as it was originally posted it could be considered an inflammatory attack on a fellow forum member.
