TabllOs, the Dodson DAC was pretty good in its day, but the Accustic Arts Tube DAC II is in another category all together. Take a look at my review of it here on the GON for more details regarding its reference level performance.
Chris, I have idea way TabIIOs would be interested in the Dodson DAC, but the Accustic Arts makes great sense, ranks up their with other reference pieces, German build quality, and finally can be purchased for a whole lot less then other reference DACS.
