Selling my Dunc/ Williams Audio Dac.
Usual build quality from Duncan - again, not new and it has the marks of experience.
Looking for £200 plus delivery costs (FOC if convenient for me to travel)
Original description
Output is slightly higher than the standard 2volts around 4/5volts, so will drive a power amp direct but is still usable with a preamp.
Spec:
Wolfson WM8740 DAC
DIR9001 digital receiver
PCM2902 USB interface
AM26C32 for SPDIF
Inputs USB, Optical or SPDIF
Input signal source scanned and selected automatically
Power supply for analog, digital and driver section are separate and independent
Double regulated before board, then step up and third stage regulation on board.
Valve output stage is SRPP using the most excellent 6N6P tube.
Input capacitors are Mundorf supreme and output capacitors are AmpOhm.
Two 6amp mains Transformers supply Dac regulators and stepped up again to provide HT for valves.
Smoothing is by quality polypropylene capacitors and choke with kiwarme resistors.
Case is solid beech sides with 5mm clear acrylic top/back and base. The top slides off for access. There is a small crack in back panel to the right hand side which isn't a problem.
The front is a sandwich of 10mm clear and 3mm transparent blue.
This thing rocks!
