I am debating between the -1 vs -2 as well, I have B&W 802 series 3 speakers in a 12x18 room. I plan on driving them with the RR2150, if it ever gets here. 95% of my listening is music, I was just looking for a little more solid bass to the music, no real interest in stomach pounding bass from movies. Any comments on the -1 vs -2 with this setup?
