I've got a Derek Shek's Nos Dacs in excellent condition together with power supply. Those interested will know just how capable this DAC is when fed by a quality transport. I remember seeing one sold a while ago for £170 plus P&P so was looking for this - [price now reduced to £140 plus P&P. Grab it while u can as it's a great DAC for the price]. I'm based in South London in case collection is preferred. Chris
