Linlai E 6sn7 tubes

My 2 matched Linlai E 6sn7 tubes arrived today. The Don Sachs Model 2 takes 4. I'll evaluate these in both circuit locations to see how they do. If prefer them to my current GE/Ken-Rad setup I'll order 2 more.

I have the older D Sachs with wood top. Two of these tubes will not fit without using a socket saver to raise one. Even then, a credit card would barely fit between them. I hear newer linestages have spaced the sockets further apart. My savers came from AES.

Initial sound is different than the GE. GE has more mid bass and beautifully sweet upper mids and highs. They can sound slightly distant in the midrange. At hour 2 the Linlai have tighter and more authoritive deep bass. They sound more linear top to bottom and very precise. The GE have more decay. This is like having 2 different preamps. 

Thanks,

Thanks for the update @aldnorab. The 100 hours of burn in that I was told I believe is very accurate. I hope they work out for you,the way they did for me. 

rocray, I miss understood. Ken Rad for KR audio which is a tube manufacture in the Czechs republic😮  

I guess I should take the time and type out KenRad vs being lazy and abbreviate. My apologies for the confusion.
