My salesman at a well-known NYC store was adament that the VTL 750's, which he sells, could not drive the big PipeDreams, and even more adament that the VAC 70/70 (65 watts/channel) could drive the big Pipes with ease.
If a tube amp doesn't have first-class power supplies and first-class output transformers, it won't drive current-hungry speakers, regardless of ostensible watts. I have VAC 140 monos on my Revel Salons in my main system, not an easy speaker to drive, and have powerful, clean, highly refined sound.
And I have heard the CAT JL1 limited editions on my best hi-fi friend's Salons. Extraordinary.
Hope this helps.
