MSRP was $450 USD ($565 CAD) Factory Direct when it was still available. I am asking for $350 firm. This is a very well reviewed, simplistic, versatile unit that can be used as a DAC, preamp and headphone amp. Excellent condition. Included is the original tube and 2 NOS Amperex 7308 PQ Holland which cost approx $50. Each have very little hours of use and only one is required at any given time in the unit.

The Tube DAC 11 retains the “tubaresent” sound but is much more extended in the high end. The smoothness and the overall balance is to die for and I can’t say this enough: that dead silent background just makes it so much easier to experience finer details in the music. It seems that as you introduce the TubeDac-11 to better equipment, the better it sounds. I know baseball is an American (of the United States variety) sport but Ian and Rachael, you have hit this one out of the park in value, versatility, fun , and sound.” Read full review here
