Highly sought after Doge 7 DAC in the top XLR balanced & RCA unbalanced option with excellent heavy duty remote and manual. Class A operation as preamplifier and powerful headphone amplifier. Fitted with 8 high-quality JJ Electronics valves: 6x 12AX7 and 2x 12AT7. In addition, two 12AT7 Sylvania matched new old stock (NOS) valves provide a 'tube rolling' upgrade option for a modest extra cost. The DAC will suit quality headphone users and/or with a full HiFi stereo system that is on the bright or analytical side where tube warmth and musicality can improve balance without sacrificing detail. My main system has a valve preamplifier and valve mono block power amplifiers and the DOGE 7 was too much of a good thing. Prefer a local Adelaide sale after demonstration but comes with full double box packaging to allow shipping. Great online reviews.
