I'm a 50-50% AV and 2-channel listener. If I start with a 990/7500/LFM-1 combo and opt to go with a couple of 2200's later (say two years)... what will I be out from an audio perspective in comparison with starting with a 7700? I've blown my budget on everything in my AV system so far...went shopping for a 42" or 50" TV and came home with a 60" Sony XBR laugh The $500 would be REALLY nice to have in my pocket...
