1) 2805: Auto EQ 2105: No Auto EQ I've read so many people that try the Auto EQ and then leave it off. Is this worth the price difference? 2) 2805: Alpha 24 processing on Front Channels 2105: No Alpha. Has anyone observed a real difference with the Alpha 24 processing, which I think is digital upconversion, between the 2105 and 2805? 3) 2805: 16 Analog Devices, 24 bit, 96 kHz high resolution DACs; 2 on each of all eight channels, in differential configuration 2105: Analog Devices, 24 bit, 96 kHz high resolution DACs Better sound on the 2805? ------- Basically, I'm wondering if the 2805 would sound better for music right now and make a better pre-pro down the line when I add a Rotel 2-channel amp. I think both of them would be fine for me for HT, and the power difference is negligible and both would be fine power-wise for now. Any comments? Thanks!
