12BH7 Nos

I dont think that there is a bad old stock 12BH7. Many talk about the RCA black plate but I have always preferred the "house" sound of Tung Sols. To my ears, RCA always had a bit or a tendency toward the warm and rich and I prefer a bit more extension and linearity. 

Thin Black plate CV5042. Not the Brimar branded 12BH7a ones. 

And what do you prefer for 12ax7 ?
I would be oriented on Raytheon, Tung-sol, Sylvania or Rca black plate.
Amplifier QS Silver mono KT88 (90watt).

Thanks!

12AX7  I've heard a lot of these. 
These are the best in my opinion.
1. Shuguang Black 12AX7LS from Grant Fidelity. (Top grade version. Need 20 hours burn in so comments based on that. The best of both 2+3 below. Black backgrounds, great soundstage, best bass and tight through the frequency range. Tons of detail.)
2. Telefunken ECC83 (clean, neutral, transparent, detailed.)
3. GE 5751 black plate triple mica (70% of the gain but grain-free and black backgrounds. Small but very detailed soundstage)

Thank you noromance.
