That Harmon AMP is way too big to put on top of a desk lol, hell the emotiva one I think might be a little long to fit on my desk.
So in terms of better sound, power, and quality I should go with the emotiva. I dont really use headphones, so I guess I wouldnt really take advantage of the headphone AMP on the N22.
pairing a sub to the emotiva AMP shouldnt really be a bi hassle correct? or would it be a bitch to really do?
