Should I swap my Onkyo 605 for a denon 5805 that I've been offered. I can live without bitstreaming if there is going to be a huge step up in quaility. My sources used with it will be samsung bdp 1400 bluray player, Toshiba A3 HDDVD player and a HTPC with bluray drive (upgrading to an ati 5000 series graphics card to get lossless through HDMI). I am really tempted as I used a denon 4806 for a while and really loved it. Used with the same sources and was really impressed. Your thoughts would be really welcome. Thanks.
