Sony PS-X9

If you're referring to replacement of the tonearm mount, that's neither here nor there, as regards the "goodness" of a PS-X9.  I do think JP likes his very much, however, at least on the technical level.  Personally, among the classic Japanese direct-drives that I don't own, I most lust for an Exclusive P3.  On the other hand, I am very very happy with what I do have.

Is this the table?

Unquestionably, an engineering masterpiece. Value  naturally, is in the wallet of the buyer.

I would test the waters however, and see where this sellers "selling price" is.

If I were into something like this, I would stress to the seller you have cash READY to wire at a better negotiable price.

$13K buys much more choice in the latest gear WITH a dealer to support your purchase.

Hi,$13k sounds high, Ive seen them sell for around £5k gbp over the years I've been looking..

Have you looked at the HW-40 by VPI? That is an impressive direct drive turntable that one might get a price close to what you would spend on the Sony.

My upgrade search began 6 months ago.  The criteria is as follows; sound, rarity and looks.  I want a "statement" piece,  with the looks and sound to match.  I thought of a Technique Sp 10 mk3, and a few others mentioned,  however, they are all readily available...

I prefer to buy "preowned", as it allows me greater options and no mark up..
