Anyone used VS-110 with KT120 for extended period?

I own an ARC VS-115. I replaced the 6550C tubes with KT-120 tubes. The sonics were improved across the board, especially the bass which is much tighter with much better slam. IMHO, it's a no brainer.

My only caveat is that you should call ARC and ask Calvin if the VS-110 can handle the KT-120. I suspect that it can, but you should check with Cal. You can also ask Cal for his opinion on swapping out the 6550C tubes for the KT-120s.

I own a VS-110 and replaced the 6550's with KT-120's 6 month's ago. I have had no problems with about 400 hours on the KT-120's. My experience with sonic improvements are the same as Bifwynne. I would heartily agree that you move to the KT-120's.
