Need tube help

[GWNG8]

Avid reader, first time poster.
My system includes B&W CM6's, Rotel RSX1056, and I'm not impressed with the 2 channel sound. I've been considering tubes & have narrowed it down to

Manley Stingray
Pros: basically 2 monoblocks sharing a chassis, great site for purchasing parts, 5 year warranty
Cons: little worried about the low power
Audiovalve Assistent 50
Pros: great power, auto biasing system, Russian mig tubes
Cons: replacement tubes not so easy to find, hot tubes in a confined, but vented box,

I listen mostly to rock, and am trying to stay around $4000, +/- for an integrated......I also think for that price I should find something that looks great as well
Any suggestions are appreciated

Welcome to HTGuide! While I don't have experience with B & W's CM line , their other speakers have a reputation for being power hungry. Have you considered a hybrid integrated? A tube pre and solid-state amp would cover your stated concerns regarding power. Vincent (one example) has a nice hybrid that puts out 150 watts per channel. It's a good bit below your cost ceiling , but maybe that's a good thing? Rogue Audio has a nice tube integrated within your range , too. No affiliation , I just wanted to say 'Welcome' and toss out another option. I'm sure some others will be by here with some good input as well.

Thanks. I hadn't looked at hybrids much, only because I wasn't sure they woudl have enough "tube" sound. I hadn't heard of Vincent, but will check them out. Rogue I had looked at once, but will give it another look.
