Psvane CV181 TII in both driver and splitter on VAC Renaissance 70/70?

Hi everyone, I dropped a pair of Psvane into my VAC ren 70/70 in the splitter sockets, and I love the improved sound.  I currently have EH in the driver sockets, and I'm considering getting another pair of Psvane to drop in there.

Problem is they're a bit pricey, and not available at the snap of a finger.   

The other issue, I've seen people say a mixed setup - one kind of tube for splitting and one for output, will yield a better sound than using the same tube for everything.  Some idea of cancelling out weaknesses vs accentuting them I think.

Anyway, I'd love to hear any thoughts on this.  The improvement from the Psvanes was enough that I'd like to see what I get.

Thanks!

I’ve always used two different kinds of input tubes (NOS) in my amps. Both tubes will contribute their characteristics to the overall sonics. For example, a Sylvania (transparent, detailed) in the gain stage and a RCA (lush, warm) as the driver/phase splitter. The best of both worlds.

Or you can have a different approach. I like transparency and realism so I'm using a pair of Sylvania VT-231 with a pair of Ken Rad VT-231. The result is neutrality and realism combined with the KR's deep bass and more forward presentation.

Thanks for the reply. You've experienced the same issue as me with new production Russian tubes. They don't reproduce a smooth, realistic top-end.

Keep us posted on your next tube roll.

Vineland, can you describe the change in sonics you're experiencing with the Psvane in the amp? 

Btw, the 70/70 is a beautiful amp.
