Richard,
Just to clarify on the Entech issue: The Entech was/is a very nice DAC. However, what I said was that I encouraged you switch back and forth between the two. You will find you probably prefer one over the other. DAC technology has come a long way in the last few years, and the upsampling chip in the 990 is very sophisticated. Of course, while I prefer the DAC set in the 990, your experience may not be the same...play around...enjoy!
