If you don't mind saving a lot of money, check out Scott-nixon.com where the "TubeDac," and matching power supply are on sale new for a price so low it might be hard to take the DAC seriously. After pioneering the tube output consumer DAC, this is the master's less is more purist approach which ended up being a bargain. The only way to make it cost more is to choose some rare, single NOS tube. My older Anodyne ATAS uses four tubes, where the cost of NOS tubes alone can equal the price of the entire, new era TubeDac. With all the money saved, you can run wild buying CD's.
