My suggestion would be to have Bob Backert at RHB Sound Dezign modify your PV-12. Stock, it has a good sound but the soundstage is flat, flat, flat, like there's just a wall you're hearing slightly behind the speakers. Bob's mods cause a huge leap forward in depth, dimensionality and imaging. And the tone and dynamics will improve as well. This is true with his circuit mods AND his power supply mods. The dynamics end up being just unbelievable.
Just my 2 cents.
