"The only Special Edition I know of is the HP version of the Dialogue Premium."
samzx12- my response was just a goof
I actually purchased a used PL a Dialogue Premium Pre with intentions of selling my HP intg. and going HP monoblocs.
Using it through the HT bypass, I heard subtle gains, although someone putting on their audiophile hat and listening, perhaps would hear more improvements?
No doubt had I went that route, there would be sonic gains, but I'm satisfied with th HP Integrated and what it does, and my WALLET is happy.
