When I had my 3B, it was mated to an Odyssey Stratos Extreme amp and I got many a goosebump. You must use the 6h23neb tubes in the preamp to get this.

When I owned the Audible Illusions 3A it was mated to a McCormack DNA-1 with revisions, the sound produced was spectacular. Keep in mind that Audible Illusion preamps are heavily regulated and are designed to work very well with solid state amps. Also Audible Illusions only produced solid state amps at one time, maybe they still do but not sure.
From Dick Olsher's 2016 review of the AI L3A:
Then, in the mid-1980s, Art discovered the Russian 6H23n-EB, really a premium version of the 6922. Not only is it a good-sounding triode, but it also happens to be rugged, exceptionally linear, low in microphonics, and, according to Art, very stable in his zero-feedback tube designs. Subsequently, all of AI’s Series 3 preamps since 1989 have this Russian tube installed in the linestage. Note that AI no longer recommends Russian-branded (e.g., Sovtek) 6922s due to poor quality control. AI will continue to use NOS Russian-military 6H23n-EB tubes until AI’s Russian distributor can no longer supply them, at which time Art says he will probably switch to the Russian 6H30 tube.
My point being the AI's stock tubes appear to be the ones you mention as having to use.
