I found it depends on your output tubes, and amp of course. I have listened to every 12BH7, 12BH7A made just about. As I am the ultimate tube tweaker. Running KT88 I preferred Matshushita seemed a bit more holgraphic with the KT88. But running El34 I preferred RCA black plates. They seemed to extend the bass a bit. For sure the RCA is the warmest I have heard.
GE 12BH7 to me was cold, with Sylvania not far behind it. But that was just in my amps.
