Parasound Preamp

I have owned the P5 and moved to the P7 for the 5.1 pass through. The 7 I thought sounds better than the 5.  Never heard the 6. The unit is a Swiss Army knife as far as features go. I love that I can use the sub with me setting for music and another for movies.  If you only need a pure pre maybe there is better. But does the money I paid I can’t beat it. I bought both used. Got all my money back on 5. And 7 I got delivered under 1k.  Super deal.
