Linlai E 6sn7 tubes

As far as longevity goes, my second pair has at least 700 hrs on them. My original pair has around 300 hrs, as far as I can recall. I haven’t swapped tubes in months.
I’m still very pleased with these. I’m listening to Shpongle/ Tales of the Inexpressible via Qobuz as I type this. Great detail,huge soundstage, and the toes are tapping!

Does the global elite model sound any better than the global?  

I have an SLP-05 too, currently using Sylvania 50's GTA.  

Thanks.

When I first goy my SLP-05 I asked Cary if 1,2 and 4,5 need to be a matched quad. The answer was no, but they do need to be the same tube.

Meaning 1,2 need to be a matched pair and 4,5 also need to be a matched pair of the same tube brand and spec, just not a fully matched quad.

@avanti1960 , with my Don Sachs, there was a big difference in my system.

@danmar123 

thanks.  did you get the Linlai global or global elite?
