Hevac1,
Well I loved my Nagra VPS so much I just bought a Nagra PLL to replace my BAT VK51SE (which I have owned for over 11 years - it started as a 50SE then upgraded).
I had to reposition my Wilson speakers a little to boost the bottom end (tuning type since the BAT was very weighty in the mids), now the PLL is giving much greater transparency, better dynamics, similar tonal balance, much better/sweeter top end and just that more real type of sound we like with our VPS.
I have the PL L stacked on top of my VFS and VPS. Looks kinda cool :).
