Forgot to add, I also auditioned EMM XDS-1 in my system and heard Esoteric K-3 in comparison to PD but in an unfamiliar system. The EMM unit is very nice, more laid back, a bit more detail than PD but I did not feel that overall it was any better. I actually prefer PD slightly over EMM but another friend of mine prefers EMM. However, considering the price difference, there was nothing much to think about. Beside, EMM can still be a bit quirky when used with computer server for hi rez material.
K-3 is a significant improvement over the older Esoteric. I used to own D05 for awhile. Much smoother midrange and high and lacked the digital glare that I did not like in D05. However, the tonal balance is still a bit too cool and lean for my taste. Another friend who has PD also comapared his to K-3, he preferred his PD but some other friends preferred K-3. So all in all, digital source at this level will depends very much on personal taste as well as the rest of the system.
