I have had great luck with the Linlai Elite E6SN7. This has turned out to be my go to tube in my preamp.
What's been your experience with New Chinese 6SN7 tube options?
By all reports, there's been a good bit of movement of talent with the Chinese tube manufacturers. Have you tried any of their offerings and in particular 6SN7 tubes?
