Linlai E 6sn7 tubes

My first bad pair came from China. My second came from Viva and are going back today. My second pair from same China source were acceptable. Tube sellers measure them but don’t have time to listen to them.

You should ask the dealer if noise testing is available. Upscale and VTS include it with every matched pair. Brent Jesse and others charge $10 per pair.

Grant Fidelity say they listen to them with headphones to ensure low noise.

Has anyone tried the globe version?

I bought the regular version, and while only 30 minutes of running, they are fairly noisy and don't have much bass at this time.

Their globe treasure are very expensive but worth the price, I bought one from GF very quiet and it throws huge soundstage , tonal balance is very good, I love it.The globe pavane are ok.

Thanks!
