The Dpr 1005 is the second model from HK. Hopefully some of the glitches that were in the first machine (dpr1001) have been worked out.
I have heard from several people that the dpr1005 and 2005 are good components. But with any new thing, it can take a while to catch on. Also, some people are not real enthusiastic about digital amps. They like their analog sound.
