Down to these three receivers... Room is 14x20, speakers are PSB T45 fronts, B25 rears, C-40 Center, 6i Sub. TV is a 42" Panasonic Plasma, source is Panasonic Blu-Ray player. System will be used about 50/50 music/movie but sound is key. NAD 765 - excellent sound, new swapable card system, HDMI 1.3a, no Dolby TrueHD, audessey roomEQ and setup ARCAM 280 - excellent sound, older no-frills system, no roomEQ, no Dolby TrueHD, no OSD Yamaha 1800 - has Dolby TrueHD (is this needed?), YPAO. I'm leaning towards the NAD but can get a good deal on both the ARCAM and Yamaha... Thanks in advance for any help/advice in picking a winner. Follow-up question, neither the NAD 765 or ARCAM 280 do audio over HDMI. Is that an issue on a 5.1 system with no plans over ever going 7.1 or 8.1?
