well, i cannot say that i know much about the P7000 sound. however, my friend owns a DMC20-II as well & it drives a Plinus SA-250 Mk4.
From whatever I know about Accuphase, it appears that this company's gear is 'musical' rather than 'accurate'. similarly, to my ears, the Plinius gear is musical rather than accurate. In my friend's system, the DMC20-SA250 combination sounds really very good. Speakers are B&W N803.
So, extrapolating from my limited experience, it would appear that an 'accurate' preamp driving a 'musical' power amp would be a good match.
This is based on just 1 data point!
Hopefully other members w/ more experience will also chime in.
