In reply to:
his original question remains unanswered, does a particular gear have any "sound quality" differences over an other particular gear
Actually jasonf's original question was:
Would the sound quality be much better with the monoblocks and Rotel over the Denon?
The only person who can answer that question IS jasonf.
Otherwise all you can do is debate whether the separates have any advantages/disadvantages in regards to features compared to integrated components which is exactly where this thread went.
