Our best opportunity before the 2006 GPAF would be the next time the Dallas Audio Club has an all member meeting. Club members already have several Scott Nixon DACs so I could bring the DAC-AH and the Onix player. I sold the Fredarray II's today and have several hundred dollars burning a hole in my pocket:) I might just order a DAC-60 too. I looked at the inside pictures and a schematic and there are wonderful opportunities for upgrading. There's a picture of the inside of an upgraded DAC-72, which is the same as the 60 except for one chip. I would include a link but it's on the Taco Bell forum, so I'm including this link to my picture pages:http://fredt300b.smugmug.com/gallery/132868/25/36512237
I have reached a final conclusion about the DAC-AH: It sounds very nice, and I prefer the overall sound to the Scott Nixon dac and the Onix XCD-88 player. It is voiced toward the warm side, which probably isn't the best match for my tube electronics and warmly voiced line arrays. It would be a super choice for a solid state mid fi system that's voiced toward the bright side - It won't attenuate the treble at all, but it will improve the treble/midbass balance. It might also be good in a system using single driver speakers that tend to be a bit light in the bass.
