I have had and continue to own a number of Prologue Products. While I have been satisfied/happy with most, I believe the the Dialogue 2 has been grossly over rated. I've upgraded from the PL1 to the DL2 in one system and am using the PL3 as my preamp in my primary system. So, having or currently owning 3 different Prima Luna products, I can tell yo that, knowing what I know now, I would not have "upgraded" to the Dialogue 2. While it's a perfectly acceptable sounding integrated, I view the sound quality only modestly different (and I don't mean better) than the Prologue 1 I previously owned. Moreover, I can tell you that in a word, the remote sucks. Unless I am 3 feet away and directly in line with it, the remote doesn't work. It's a good thing for me a that my cd player has both a power and volume control, as I never use the DL2 remote.
In the end, I know that this wasn't your question, but my recommendation is ad the PL1 or PL2 to your system, not the DL2
