Joseph,
I have 2 guesses. 1, also that the unit may be defective, which was common with the first batch of these as mentioned, but no problems on newer units, at least according to my dealer. Second guess is that the Sony makes for a poor transport. I've paired my MF A3 24 dac with a handful of transports, and, for example, it sounded plain awful with my DVD player, mundane with a Pioneer elite cd player or Jolida JD100 as tranpsorts. When attached to a Theta dedicated transport its pure magic. There is no way the Sony 999 can touch it in redbook, even in sacd with the Sony I would probably still favor the MF on redbook for a more fleshed out presentation while still having exceptional openness, clarity, smoothness, presence, detail retrieveal and extension into the heavens, this on the hundreds of cd's I own, not just the 5 SACD would ever buy with what is out there currently. It really can be that good. Again, this dac is extremely transport dependent, what may have worked with other dacs won't for sure work with this one, at least in my experience with it. If garbage goes into the dac on more trash comes out, it is highly revealing and unforgiving.
