I'm thinking of getting into tubes, what do you

System update. OK, here goes. First I put a Concierto power cord (I had left over from another system) on the VK-200 amplifier and put the amp on it's own dedicated circuit (the way I had done with my Krells). This brought some really big improvement in the bass. Then I moved the speaker cable connections on the B&W 801 Matrix IIIs to the midrange/tweeter connectors (there are straps between those and the woofer connections). This last change, and lots of playing time, has brought about the most surprising improvements. Much better, tighter more defined bass, much less 'smearing' of the midrange and a whole lot better imaging. And, although I bought the BAT pieces used, the equipment didn't appear to have had any use, or very little, at all. So I suspect that a lot of burn in time is needed.

Another update: Concierto Concert Grand power cable on the VK-200 and the older Concierto power cable moved to the preamp. About 90 hours of playing/burn in time. HUGE improvements all around!!! Much more open sounding most (about 95%) of the veil is gone. The bass is tightening up beautifully. And there is much more detail coming through. TAS said they needed 400 hours on the KV-30SE, so I'm looking for more improvements to come.

Gfloyd53,
Just got caught up on this thread. Sorry to have left you hanging. I think the break-in was the key to your initial issues.
From your comment about jumpers, it sounds like the speakers are bi-wirable. I'd post a question in speaker forum or search archives re: B&W biwiring. On some speakers it makes tons of difference. You might be able to borrow someone else's biwires and give it a try. B&W dealers would also have recommendations.
Lastly, BAT gear is made balanced and strongly prefers balanced XLR interconnects. Hope you are using them. If not, you aren't hearing all that you paid for. Even lower priced balanced cables can outperform some higher-priced singe-ended cables with their gear.
Keep us updated, you're well on your way. Cheers, Spencer

Hello again Sbank,
Yes. I'm using XLR connections. I may be doing biwires someday. I have in the past like when I was using Synergistic Reaearch Designer's Reference and Resolution Reference with the big Krell KAS2 amplifiers. It was better than either single run. But, Siltech G5 Signature Echo Bay single run sounded better than anything else by a LONNNNG shot! However, I never tried biwiring with the Siltechs (too expensive anyway). The next thing I'm considreing for the B&W 801s is the Northcreek external crossover. It will be awhile before I get around to it though.

Thanks to everyone for their advice. However, I'm leaving tubes behind. The combo was really starting to open up and was starting sound pretty good when a tube or tubes in the preamp decided to act up. I called Kevin at Upscale audio and after describing the sound he agreed that it was probably one of the tubes. So, I sold the VK-30 as needing tubes. However I might stay with BAT solid state designs.
