I just received my Linlai E-6SN7 tubes and installed them into my T+A S10 Amplifier. As many have shared, it is a very full-sounding tube with good definition, but it is a bit dark to start. I’m on hour three and will be running these nonstop for the next few days. I think this combo on this amp, paired to Vivid Audio Kaya 90 speakers will be quite special.
I’ve had a lot of experience with Psvane ACME and some Linlai Elite and they have never disappointed. FWIW, I received confirmation from Austin at Viva Tubes that the Linlai E-6SN7 is the same exact tube as the Linlai Global Elite 6SN7. They only differences are that the E-6SN7 is manufactured for the Eastern markets, and Global Elite are exports for the Western markets. Viva Tubes buys direct from the Chinese factory, so they have the Eastern tubes in stock. Of course, purchasing from Grant Fidelity guarantees more stringent tolerances, but I haven’t really had any issues with Viva Tubes. If I ever have issues, they have always been able to replace a tube with no hassle.
