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!

My preamp has two pairs of 6SN7 signal and driver tubes, and while I enjoyed splitting tubes with one pair of new, and a second pair of my best NOS tubes, what worked best was two very closely matched pairs/triodes of the same brand of boutique tubes.  The tubes are from a related company who ended up selling their tooling to PSVANE, running a quad of them now, sound fantastic. The NOS are now sitting in a box.    
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.




I really appreciate all the input here.

Well, I have some sylvanias and rcas arriving soon.  And hopefully I'll get to drop them in soon, I'll prob start with an RCA/Psvane combo, then try the Sylvania/Psvane.  Lot's of combos to try out, but some break in first.

The second set of Psvane is tempting, and I may  just have to roll the dice on an order, and play with them when / if they get here.  But maybe these NOS will be a great stopping point.

I'll keep you posted!

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.
