SST, USSR/Volti, Maine/Nordost, Massachusetts
Sorokin’s latest venture, STT Audio, showed two products. The first, The Essence tube SE monoblock integrated amplifier ($62,000/pair), is a 40Wpc baby that can accommodate 10 different kinds of tubes. “You pick the icon of the tube and it self-adjusts,” Sorokin told us. The day before, he had paired T120s with KT88s; we heard A13s and EL34s. Note that the bottom of the amp is Titanium, and covered with indentations to allow fine placement of Nordost Corporation’s Brass Sort Kones in order to control room resonances.
Also shown was SST’s work-in-progress active crossover/preamplifier (maybe $38,000). It combines an active tube crossover with a six-input preamplifier/selector. The source was a dCS Puccini CD/SACD playerthe same superb unit I have at homeused solely as a transport, and a dCS Elgar DAC. Speakers were cousins of the excellent babies that closed out my second day of blogging with such beautiful sound, the Volti Audio 99dB-sensitive Alura A 15/MT1 ($13,900/pair). These 3-ways have a 15" bass driver in a bass reflex cabinet, 2"-outlet midrange compression driver, wooden Tractrix midrange horn, 1" high-frequency compression driver, elliptical Tractrix tweeter horn, and hand-wired passive crossover networks, housed in all Baltic Birch plywood. Expect Volti Audio to distribute SST in the US before long.
