I already made the move to purchase the Delta 410. I should have it by next week. Was this a wise move? I'll be using it for DVD playback - DD & DTS. CD playback. MP3 Playback. TIVO functions. I will have my Yamaha rx-v2095 doing the decoding. Will I really hear a sonic difference between the SB Live! that I'm using now and the Delte 410? Should I stick with XP?
