Why so few turntable reviews?

Hmmm, I am not so sure that the "current" LP movement as you call it will die off anytime soon. There are good reasons why this format never died to begin with, and until digital provides the same level of emotional engagement to the listening experience, I think we'll see it hang around indefinitely. Also, the interactive aspect of this format is part of the fun. Used LPs of good quality are still abundant and cheap where I live (~$1 a piece used).

Having said that, I also look forward to when they return to $0.20 again!

I've posted a couple of VPI turntable reviews on Audio Asylum. I tried to be subjective and concise.
Perhaps - as you said Elizabeth - t/t's are an anachronism and the market for them is tiny.
Count me in amongst the old farts who have never given up on vinyl! My view is that the vinyl revival will out last you and I.

Perhaps because the differences in the cartridge, tonearm and phono stage dwarf differences between turntables?

It is a curious observation an a true one at that. You hardly ever see one on a cover of an audio mag. Unless it is a statement piece(Like high cost Caliburn). Otherwise you might find some review in an analog corner or something. Besides there are not too many newer models being made.I guess demand being low. I am also beginning to think that Elizabeth may be right.
