NOS tube alternatives for Herron VTSP 3A r02


Looking for advice from actual Herron preamp owners who have experimented with different tubes. Recently acquired Herron  VTSP 3A r02 to be used with CAT JL5 amp. Speakers are Dynaudio C4s & ATC SCM19v2s.

I´m fully aware that manufacturer advises against tube rolling citing preamp was voiced with especially screened & selected modern tubes but I´ve decided to disregard for the following reasons:

Unit was purchased used & came with new tubes that are not originally from Herron & IM(not so humble)O & experience current production Russian and Chinese are vastly inferior in tone & timbre to NOS Telefunkens, Siemens and Amperex in relation to 6922 variants.

Thanks

Calling it "voiced" carries the unfortunate implication of looking for a particular characteristic sound. Which is unfortunate since the main thing the VTPH2A hit me with is its lack of voice or character. It made the previous ARC sound downright woody and colored. 

Given the history, used gear, tube rolling, I'm not at all surprised you played around and found something better. What would surprise me is if you called Keith and didn't find whatever he sends you at least as good.

Who cares about mileage, really? Its the road. The car. And most of all the driver.
Keith told me he goes through something like 10 tubes that don't make the cut for each one he uses. This is after having selected the best tube type. This is just comparing the same tubes for quality and matching. He told me he has a barrel full of rejects. Which people are always asking to buy, because even some of his rejects are better than 95% of what they would otherwise get just rolling the dice on the market.

Which come to think of it, is what it should be called. Not tube rolling. Rolling the dice.

Or just buy tubes from Keith. 

(The more you talk to Keith the more amazed you are at what a stone bargain his stuff is. As if the sound alone wasn't enough...)
