Hi jb,
Can I ask what Pre-Amp/Power Amp you are using? I just had an interesting experience tube rolling. Rolled in 3 Psvane 12AX7-11 into my Vincent SA-T8. Wow! What an improvement. Sounded great with both my Vincent s/s SP-998 Mono Blocks & upgraded s/s Benchmark Plexus Power Amp. Immediately ordered a quad of Psvane 12AU7-11 to replace the "no-name" Chinese 12AU7's in the SA-T8. I switched on the Benchmark Power Amp. Yuk, way, way too bright sounding. I switched back in the Vincent Mono Blacks. Voila! Absolute magic! Dynamics, depth, soundstage etc. just exploded.
So, initially putting the 3 Psvane 12AX7's in the SA-T8 and both Power Amp & Mono Blocks sound really good. Then roll in 4 Psvane 12AU7's as well, (so all 7 tubes in Pre. are now Psvane) and when connect up Power Amp sound not so good but sound when Mono Blocks connected, awesome. Difference is staggering. Must be incredible synergy and non-synergy going on. I suppose some more experienced tube rollers would be able to relate some similar expriences.
