If you are really in the market, have you looked on Audiogon or USAudiomart recently? There is plenty to chose from at attractive prices.
Is it true? Go to hifishark and filter by "North America". Then I see none of the Reference 3 phono preamp - don’t confuse those numerous & ancient Ref 3 line stages with the Ref 3 phono stage he (presumably) wants. There are a couple Ref 3SE phonos - 1 priced way above market, the other replicated on a few sites (TMR) and still a bit above market. There’s 1 Ref 2SE phono in Canada. And there’s 1 Ref 6 line stage (which actually used to be mine - nice unit). Definitely no glut of cut-rate units in those three recent-ish models. If you go back to the much older models (like Ref 3 line stage), yeah you could consider that a glut, but it's more understandable.
