Beaux ARTs

Driving the distinctive Scaena "iso-linear array" loudspeakers in the Audio Doctor suite was a pair of Conrad-Johnson's limited-edition ART amplifiers ($37,000/pair): one of 125 pairs in existence. These ARTs used KT-120 output tubes (the amps are rated at 275Wpc when run with 6550 pentodes) and were operated without their strikingly pretty tube cages.
