I have two receivers, Harman Kardon AVR254 (been using this since 2009 and has no issues that I know of) and Denon 1612 (just bought it used off of CL yesterday and it's in excellent shape) and I'd like to ask which receiver is overall better than the other. I like the convenience that Denon 1612 has a USB port in the front to which I assume I can connect my iPhone 5 and USB thumb drive, but not sure which one has better sound quality.
My speakers are Cambridge S30's for front, Boston Acoustics CS-225C center (I'm not sure if I'll be using the Boston or just S30's) and BIC PL-200 subwoofer.
Which receiver would you recommend as a main receiver? The other receiver will be set up in my upstair loft with smaller speakers.
