6692: what is the best upgrade to aim for?

I have ARC PH3 hybrid phono preamp that I want to upgrade in the future.
Currently I use Sovtek 6692.

Not as good as the Siemens E88CCs, but I have been having some microphonics problems with the Siemens. The 6H23s from Conus are way cheaper, too.

If I contact conus or upscale, are they trustworthy to be able to recommend good upgrade tubes for my BAT vk-3i? I am not knowledgeable about tubes, but would like to experiment a bit. pcanis

A bit noisey, but very musical. Upscale will not sell 6922 tubes unless you bought from them equipment. I have also used the 6H23n in place of Sovtek in the BAT5 preamp, but the last and most critical tubes, I still use Amperex 7308, at least that saves a lot of money (8 tubes in BAT5).
