Yes, the Popes have gooten almost impossible to get...as for sound I still like them better then the RCA/Sylvainia GTB's. I would like to try some Tung Sol RP and some Russian 1578's. The cost has just gotten out of control on these though. I'm so happy with the Popes (and have many of them) that I'm inclined to stick with them unless I find some NOS Russian/RP's on my frequent search.
Tvad-
my amps imput impedance is 100K and the SLP-05 and Clayton match is great IMO.
