I use a couple on my BDP 83. A few in fact, from time to time. Nirvana digital pc, VD power III, Voodoo Black Dragon, or Taipan Helix. Of them I usually prefer the Nirvana on the Oppo.
Again, on the BC DAC 3 I use either a Taipan HA, or a Voodoo Tesla II, Depending on mood and application.
I'd like to have a couple more pc's actually.
Personally, I'd remove that amp from the PSA cond, if it isn't already... and run the balance of the gear on it. Sources, proc, TV.
Depending on which approach you require for a pc here or therre, the smoother sounding ones IMO are the Black Dragon, & Nirvana. the more dynamic ones would be the Gold dragons, Tesla II and Taipan HA.
IMHO Smooth = softer leading edge yet still having impact ... just not quite so sharpened.
IMHO Dynamic = Sharper leading edge and tighter more propulsive presentation..
All are refined and quite listenable without listener fatigue. Save for the Vooddo Tesla II, all are in the $300s preowned or less. The vD P III goes for less than $125 most of the time. It's a nice cord but that's about it. it's also a bit unwieldy. Stiff and heavy. All the other's are very light and quite easy to manage.
the voodoo Gold dragon & Tesla ii surpass the $300-400 range, with the TESLA ii running around $500 used. Ive had mine for sometime now and been well pleased even with several component changes along the way.
Which cord you choose to use where is important. Id say the supply cord feeding that Premier cond is your more important one. I use an Elrod Sig III for power items, and a Python VX for digital stuff usually. My dac comes off the Elrod supplied Haley though. My proc goes right off the wall outlets dedicated ckt.
One last bit there maybe pcs under 300 that might help you out, but I never did find any that were of any great significance. I had to mmove into those I have now and buy carefully. The VA Airsine is reportedly a quite nice pc but theyre hard to get preowned, which might say something too as they go like Voodoo cables FAST and run in the high 400s or better.
Good luck.
