Hi,
So I've had the PLL in my system for 24 hours.
(SME 20/2, SME IV.Vi, Lyra Skala, Purist cabling, Wilson Maxx 3's, BAT 75se/150se amps).
I just LOVE my Nagra VPS.
The PLL delivers loads of tranparency, a nice top end, killer imaging-All a step up from my BAT 51SE. Seems to miss that "weight" on each of musical notes. I am not sure I can part with that portion of the BAT sound. Maybe I am addicted to the "bat sound" at this point. Your comment about splitting hairs is spot on. Both the Nagra PLL and BAT51SE are very nice - just different.
Anyway, my dealer also brought the Nagra VFS by. Oh my gosh were you right there. I am buying it for my VPS.
As for the preamp, right now I am inclined to keep my BAT 51SE or try the 52SE/REX next...
