AliExpress & Linlai Tubes- Anyone have experience?

Purchasing Linlai from Chinese sellers has not been good experience for me, two failures of 101D tubes. You should realize Chinese sellers getting tubes from Chinese stocks with much more variable quality. North American sellers who purchase in relatively large quantities demand better quality, they can't accept high failure rates and maintain their reputation and position in marketplace. To me its worth paying the premium for NA stock. Replacement for failed tubes is another issue, think about shipping and handling time frames.

I recently purchased a pair of Linlai Elite E-6SN7 from an eBay seller from China with a 100% positive feedback.  I paid via PP so at least I had some protection if something went south.  They were delivered to my door in 18 days from date of purchase. 
 

   They sound fantastic,and are dead quiet. Of course,YMMV.
