I've been using those expensive high test Mullards from Upscale for a while now. Conrad Johnson PV10 tube pre-amp with ss monoblocks and the KEF ls50 with REL T5 subs. The mullards sound good in this application because they smooth it out a little.

Looking for suggestions for 12AU7 driver tubes in power amp. Looking for suggestions on NOS but affordable. Thank you in advance!
