Summary: I bought this receiver to replace an old Sony 5.1 that did not have HDMI. I choose the Pioneer VSX-520-K because it was reasonably priced and had the HDMI pass-through. When it arrived and I set up the system, the audio would not calibrate correctly.
Summary: I purchased my first of this receiver and found it had a problem sending any signal to the Subwoofer PreOut port on the rear panel. Pioneer tech support confirmed there was a short in that port. Receiver sent back to amazon for replacement.
