Ali codes at the end of the description - down below.

These tubes were one of your (yes, it came from you, guys!) recommendations for instant Cary SLP-90 clone upgrade. Art-S are more expensive, these are cheaper - no brainer for the price - and the replacement takes like 10-15 minutes with instant sound quality reward.
I got a set to test how much improvement there is and you were right: the sound quality change is siginficant (and of course for the better) and the price really is good.

You can get them (matched quad) in official PSVANE store here:

(nevermind weird "stainless steel case", the link is good ;) )

These are also available on Aliexpress in official PSVANE store here:
