Really like/love the Shuguang WE6SN7 replica tubes in my Dennis Had Inspire headphone/preamp and use that piece in both modes. Bought a set off ebay from a Chinese vender with great results and after the plant burnt was able to buy a slightly used pair that were sourced from Grant Fidelity as back ups.
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?
