Rare opportunity to acquire an original UK voltage model of this highly acclaimed tube output DAC. Absolutely mint condition, approx 1 year old, relatively light use. The Sigma (model below this one) saw off - in the minds of many- a Chord DAC 64 at bake-off a while back. Having gone from a DAC 64 to this myself, I can attest to the fact that although the DAC 64 might arguably do more "hi fi", the Alpha does waaay more music in a natural, fluid, more listenable way. Superb open, musical performance only selling due to upgrade. Complete with a small collection of alternative 12ax7 valves for your tube rolling amusement!
