I have read the comparisons on this forum. And that is my point exactly! Most other digital reviews done by 6moon uses the Bel Canto DAC-2 as a reference for comparison. Yes they did mention the Audio Note DAC 1, but I can't ever remember them using that DAC or the Rotel RCD-971 as a reference for comparison. They chose to use the Rotel and a cheap DVD player as transport. They did not us inferior transports with the Bel Canto review or the Birdland. I don't mean to be over critical of 6moons, however, I don't feel that they gave the Tube DAC the same consideration they gave the other DACs. I'm not implying this was intentional, but I do feel it is unfair.
