Weighing in a bit on this conversation. First, somebody said there is no sub out on the 1120. There is and it works very well.
60w is enough for speaker above 91DB sensibility, IMHO.
I was able to compare room perfect versus Dirac, and it’s no match. You should really make sure it’s set up properly, then compare it to other amplifier .
I don’t think anyone can really expect a wow effect with an amplifier. An amp is an amp, it won’t change the nature of your sound, except a very bad one: your room , your speakers will.
But trying room perfect, I really did get this wow effect. Make sure the room correction is set up properly (that’s no easy task, you have to put in the right delay for the sub), to 100%, then compare without it. I’m sure you will end up keeping the 1120.
I meant to say "not a dedicated" subwoofer output but rather a generic one. I feel, and might be wrong, that a dedicated sub out offers better results. But that's pure assumption from my part.
