Bruce, yes, my amp is a VAC Renaissance 70/70 MkIII, from about a dozen or so years ago, but it has little if any similarity to the amps VAC currently produces (aside from having been designed in a robust manner by the same designer, Kevin Hayes). My amp uses four 300B directly heated triode power tubes per side, in push-pull parallel, providing 65 watts. The current VAC amps are all KT88-based, and are considerably more powerful. I don't need a great deal of power, as you'll recall, because of the efficiency and easy to drive impedance characteristics of my speakers.
The VAC 450S, btw, that was indicated by several people earlier in this thread as being particularly synergistic with the S5, cost $39K as of a couple of years ago. Its power supply and amplifier chassis together way 200+ pounds! And the other two amps in the 450 series are monoblocks weighing that much per side, and costing two and three times that amount, respectively!
All of those amps, btw, have output taps described as being suitable for 2 ohm loads. Mine even has a tap designated as being for 1 to 2 ohm loads.
