Differences in sound in Parasound P3 and P5

Hi Erik.  Im not sure if I wanna stretch that far.  Ive read plenty of good things about the P7, and if I could afford it right now, I would get it, or a nice tubed pre. I've read a lot of good stuff on the Schiit Freya too, and a lot of bad as well.  I would assume the p7 and the Freya are in two separate leagues.  Again, I assume.  If the price for a used p7 is right, I might just go it's route.

Thanks!

The Parasound P5 is a current product, but if you look internally you will see a switching power supply and rather lean circuit board.

The P3 is a discontinued product, but it has a beefy linear power supply and much more in the audio circuit.  I would choose the P3.
