No static, better than Nobsound defaults!
I'm giving them a five against the tubes that came with my nobsound NS-80E... These absolutely add brightness and crispness from those tubes.Honestly those nobsound tubes aren't that bad. I have a pair of Beyerdynamic DT 770 Pro headphones at home, and I think that it actually jacked the bass/volume ability up a bit, but it could be a bit of "they sound better in general" placebo.

Quite a bit of background static
These work fairly well when sound is running through them, but without any audio, they emit a constant hiss that's noticeably louder than other tubes of the same form factor. Not horrible, but wouldn't recommend.

The real thing, a bargain, very serious seller, and a pleasure to use!
I was very happy with everything about the transaction, and the product sounded excellent, especially for the money. Riverstone is very unusual in providing very detailed specs about everything connected with the product, as well as providing an unprecedented guarantee. And the best Russian new or NOS NIB tubes have clearly come a long way.
