IC Ortofon SPU Royal N Cartridge

Interest Check at the moment:
Ortofon SPU Royal N Cartidge

With the arrival of Petrat's SPU Anniversary 95 (A95) to sit along side a Jan Allaerts MC1 Boron I have a
potential oppotunity for someone to take custody of this great cartridge. I just can't keep this amount of stereo cartridges!

For those of you unfamiliar with the SPU Royal N, it is a Nude SPU which is not housed in the traditional SPU Ortofon headshell.
Without the SPU headshell this allows direct mounting of this SPU cartridge on to fixed headshell tonearms, as well as of course mounting into a detachable universal headshell.

The SPU Royal N is a very special cartridge and there are plenty of online reviews to gander.

I can only add that it presents very special music, nicely weighty with the signature SPU full bodied delivery but because this cartridge employs Gold Coils and the wonderful Replicant 100 Stylus, it has a great deal of detail and open airy space, whilst delivering solid well controlled bass. 

The history of this particular piece?, well it was Tom's (montesquieu) up until August last year where it resided along side an array of
Analogue delights, thus it was virtually idol as Tom's stable of Ikeda and Miyajimas and Monos were heavily on duty.

I have used it sporadically but lightly since and is on rotation with a Jan Allaerts MC1 Boron a fantastic SAEC C3 MC and 3 Mono cartridges,
so you can see it isn't over used!!

It has been sent away to j7 (Audio Origami) for a detailed inspection, where Johnny had it under the microscope and offered these comments
"stylis looks brand new !!! cant see any wear at all!" 

please see Amazing pictures of the stylus that j7 sent back...incredible pics!

Anyway it's a hard one to let this go and TBH I'll be happy if it stays as it does deliver a different presentaion with the Replicant 100 stylus than the standard Elliptical tipped SPUs.

Ortofon SPU N headshell adaptor included with cartridge.

If she does go, I'll be needing £675 which is a very fair price given the quality of cartridge and condition.
Included insured Royal Mail delivery in the UK. (more abroad!)

The FR headshell in the pictures is NOT for sale and not included.

That was quick, well done. But god that text with the yellow background was just awfully difficult to read, I stopped halfway down it was such a nightmare.
