VTL ST 150, Audio Research VT 100, mk. II

I owned a the ST150 and had it paired with the AI M3B. It smoked the McIntosh MC402 it replaced big time. Far better dynamics and PRAT for about half the price. VTL will also outperform the QS amps from what I recall (having owned the Silver 60's and Silver 90's). The only reason I sold it was to pick up a pair of vintage VTL compact 100's ( el34 based).

Good luck

Glad you mentioned Quicksilver a classic combination is Audible Illusions, Quicksilver, Vandersteen. You will not find a more reliable tube amp than QS, and I'm pretty sure Richard Vandersteen owned QS V4s. I think this combination was popularized by John Rutan of Audio Connection in New Jersey - I also think he is Vandersteens largest retailer over the years. Oh, yeah, and a breeze to bias - that is important to me, and maybe you.

Thanks to all for your input. I went after a pair of Quicksilvers but didn't land them. I found a pair of Prima Luna 6 amps from Upscale Audio. They sound and look great and are easy to use and maintain. The warranty, advice and warranty also added to the deal.
Thanks,
Don
