Just ordered a AVR 520. I couldn't believe how low this was going for considering it does 7.1, the internal amps allow for any inputs (there's a jumper on the back that allows this!), 6.1 input, 7.1 pre-outs, Logic 7 for 2-ch sources, component switching, a host of other great features...AND MP3 decoding. What's wrong with H/K that they are selling this thing so low compared to comparable receivers from Onkyo (797) and Denon (3802)? Anyhow, I wonder how the decoding quality is. Also, to H/K owners with this capabilities...how do you send it MP3 data? The only way I know of is through an HTPC. I haven't seen a standalone MP3 player with digital out yet. BTW, I picked this up from Onecall for $627 shipped. Ecost.com also has it for $628 shipped. Both are listed as authorized on HK's site.
