ARC VM 220 WITH VANDERSTEEN WOOD QUATRO


I am looking for a little guidance, The pre is ARC LS 25mk2 and the amp is ARC VM-220 mono's hook-up to a set of Wood Quatro's. When i turn up the volume past half way, I seam to be losing the warmth of the tubes, Its sounds alittle (forced, less detailed) not sure how to explain it, just different. I biased the tubes all at 65. was wondering if i need to switch to Tung-sol KT120 tubes or go with a different set of speakers, higher in sensitivity, or is this headed in the wrong direction.thanks

Sometimes when you drive a system too hard...it becomes brittle. Distortion, dynamics being ltd. Yes, you might try KT120s...but i would be most curious as to what would happen if you changed amps to a bigger ARC mono.
I always wanted to like ARC but never could. Always a little metallic or thin to my ears. It might be interesting to try something like a Luxman 590AII before dumping the speakers. Not a huge investment for you and it would be a big change.
Just a suggestion -- Call John Rutan at Audio Connection in Verona NJ. He is an authorized dealer for both Vandies and ARC and knows his gear. He might be able to help.
