Rec a 300B for Wavelength Cardinal Monoblocks


I am looking for recommendations for 300B tube choices for my Wavelength Cardinal Monoblock amps. My speakers are the Auditorium-23 Solovox and the preamp is a Shindo Masseto. I know that I will eventually get a Shindo amplifier, but for now I am intrigued by the prospect of learning how much better the Cardinals can sound with other tubes. Also, there is the very real possibility that I would keep the Cardinals and alternate them with the future Shindo amp, assuming the Shindo amp does not use 300B's. Thanks in advance for all guidance!
Best Regards,
Steven

best bet would be to contact Gordon Rankin of Wavelength direct ... I BELIEVE there was a version designed specifically for the WE 300B but my memory could be faulty.

In any event Gordon most likely tried them with a number of 300B tubes during the development process
Jrinkerptdnet - Thank you. I will indeed be contacting Gordon before pulling the trigger on different tubes. And I probably should have mentioned that, as I recall, the 300B tubes in my Cardinals are the ones that Gordon prefers. I just now took a look at those tubes and cannot easily make out the brand name.
Best Regards,

I have a Wavelength Triton Blue NCE and I use Western Electric 300B's, I bought them in 2000 and they still sound good.
I also have Treasure 330B's and they are ok for the money but not as good as WE.

If you get a recommendation from Gordon please post it , I was thinking about trying another 300b tube
