TGW,
Many thanks for that info. I did p.m. you when I realised that the transformers may have been what you had suggested, but you've anwered my queries in your posting.
You are obviously more technically advanced than I, and familiar with this approach, as is Marco. I wouldn't know if the gain (1;10) would be enough for the .6mv output of the Black, though you say it is adjustable. How on Earth are these powered? Or are they passive devices?
I'm obviously tempted, not least by the value for money aspect you mention, but then I'd have to source a mm phono stage and get SME to shorten the overlong arm leads that used to pick up RFI when I had on-board phono cards.
I have twice as many non-classical records, and a VPI 16.5, which does a reasonable job, but doesn't repair groove damage!
I've had the Black for just three weeks, and it seems to improve with listening in an analogue way. From Ortophon, Linn, Roksan and 2 Lyra carts. vinyl seemed to be more CD-like, so the Koetsu is a refreshing change which I'm sure will endure.
Marco has suggested the pragmatic solution of a s/s active stage (like the Superline, e.g.), which appeals because (a) it's only one unit with minimal hassle factor, and, (b) I understand that approach.
I really cannot imagine the different sonic rewards of these two approaches. though I suspect the 'purist?' transformer route may have the edge in what Marco feels is my rather revealing system (and I don't think he's far out, to judge by recent visitors' comments).
Shall have to play this one by ear, I think. Can't think there'll be too many of that calibre of transformer coming onto the market, though!.
