A few months ago I bought the Denon AVR 4520CI for $400. It's a 150 watt, 9.2 channel receiver with 11.2 channel processing, which I considered a great deal at the time. The receiver is in mint condition with everything included, he even threw in two 20mm cooling fans. I'm questioning my decision based on DTS Neo X and Audyssey DSX being formats not being used in movie soundtracks today. Did I make a big mistake or is this receiver a worthy addition to my collection? I would like to hear from owners and people familiar with this receiver. I understand that, what sounds good to me is what's important, but on movie night with guest, that's a different story. Thank you in advance.
