The Thrax Audio Spartacus 300 monoblock tube amplifiers have landed at Audio Atelier Singapore. Each of the monoblocks uses six 300B tubes – 1 for voltage regulation, 1 input tube, and 4 output tube – giving a pure 300B signal path. “This is the second pair of Spartacus 300 in Singapore. The first pair was sold to a satisfied customer who traded in his Kondo monoblocks.”
