Selling my long-term Audio-gd Reference 5.2 DAC in great condition. Features are as follows: Uses 4x Burr Brown PCM1704-UK chips - this is likely the cheapest PCM1704 R2R DAC on the market! 5 digital inputs (BNC, RCA, 2x Toslink, USB) Fully balanced and single-ended outputs Choice of oversampling modes (2x, 4x, 8x or NOS) Adjustable High/Low gain on the output The unit was purchased with a BNC input fitted (replacing one of the SPDIF RCAs) and has the preferred DIR9001 SPDIF receiver installed (I'll also include the alternative WM8805 module). I have the original box so shipping within Australia will be easy - PM me for a quote. Local pickup in Melbourne is also welcome. Payment via cash (pickup), bank transfer or PayPal (buyer pays fees). More info here (the Ref 5.32 is the same as the Ref 5.2 but has the newer USB-32 module): http://www.audio-gd.com/Pro/dac/RE5.2/RE5.2EN.htm Review of the Reference 7.1 (very similar design): http://www.digitalaudioreview.net/2011/04/audio-gd-reference-71-dac-8-x-pcm1704uk/ Pics show the unit with the case off while I was trying out different oversampling settings - the unit will come fully assembled.
