A great vintage dac from the past. When used with a good DDC, it basically sounds like an Yggdrasil-lite to me. Obviously not as refined sounding, but I think it definitely competes with modern dacs especially at the price it can be found for sometimes. Please let me know if any of you are interested! It's about as big as an Yggdrasil but slightly shorter and half the weight.
