tubes and rock and roll, good fit?

Dude,

Tubes, shmubes. In the league you are playing in with that gear you own and are considering, it shouldn't matter. It all should sound fantastic all the time as long as the pieces are matched to work well together and to the listening room and your taste.

I thought the same with the Altairs + tubes but perhaps it does't matter with a monstrous tube amp like that VTL. If it were me, I'd be concerned going in, not just about sound quality, but reliability of a big tube amp like that driving a 4 ohm or less load. You might end up yearning for the good old simple days of care free SS amplification.

I'd listen to them together first before jumping for sure though, especially if rock with maximum possible impact is a desire! You are using big Krells now I believe? That should be hard to beat I would think!

I used to rock with VTL 300/Kef 107's when they first came out. I now run a Krell 300S/B&W N802 for reliability and cost unless you can afford to keep fresh tubes running. It is a fine line and each has desirable benefits to offer. I have enjoyed the speed, impact and dynamics of the Krell for the last decade, even tried others and came back. Tvad said it right first and match is always first.

You're bored.
