I've been using the Linlai Elite from Grant Fidelity in my integrated amp and they sound really sweet. I tried them in the Freya + and they were OK but sounded better in my integrated amp. The Shugang WE 6sn7 were also OK in the Freya but a little congested in the bottom end. Just received some PSvane 6sn7 from Viva Tubes and they will need a lot of breaking in. The sound was restrained from top to bottom. So far, the best is Silvania 6sn7's. Great tone!
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?
