As a BAT vk50SE and Watt Puppy 6.0 owner, I'll respectively disagree with the poster above. Please check out my system pics posted in the virtual systems page. I've used my VK50SE for 3.5 years in a combo audio/video setup. it's on about 3-4 hours a day during the week, and at least 8-12 hours each weekend day. Wear and tear is NOT a issue on the VK50se. The tubes are stil the originals, it sounds spectacular. I use the standby mode when not listening for more than a few mores...like when I go to bed or work. other wise, it's pretty much on playing tunes or watching dvds.
Go for the sound quality, the BAT pre will be awesome in your setup...you won't be disappointed. It sound great on DVD, DSS, HDTV, and of course MUSIC.
