Linlai E 6sn7 tubes

I understand what he wrote, but WHY do the tubes sound different?

I have to say that I’ve been confused about global, non global…… Last night I’m doing some listening,and whatever it’s worth,the Linlai’s that I currently run, sound better in my Motherlode II than any other tube I currently own. Now, I’m not saying that I have experience with 100’s of NOS tubes,and I am the ultimate expert.  I am a relative novice in comparison to others that share their knowledge here.  Other than the cathode material incident, these tubes have been silent, and give me a great textured, full spectrum response with a bigger soundstage than I have experienced before. However,we all hear,and desire something a little different.   I mentioned earlier about the value about ordering from a reputable dealer vs ordering from an epay vendor.  That,of course,still stands.  As with most things in life,proceed with caution, and do what you are comfortable with. 

@danmar123   I may have missed out on a thread. Do they sound different?

Pinwa, Many audiophile here have said Grant Fidelity had high quality tube, I agree I have tasted their quality tube compare to some of the US dealers.But you have to pay premium price, Is it worth it? Yes it is.
