Phantom + A90 question

Isn't the cadenza the same body type as the Jubilee? This is the first I have heard of a quirky design...

Any cartridge (or headshell) with a non-flat mounting surface is potentially quirky. For a manufacturer to offer two such models isn't less so, it's doubly so.

Owners who wish to reduce cartridge/headshell contact can use aftermarket, point-contact spacers. The 3-pointed ones from Mapleshade can be fitted with the single point toward the front or the rear, which doubles the chances of a fit. Accordingly, they may be regarded as semi-quirky.

I am going to take a closer look at my A90 mount. It didn't even think it was an issue. Perhaps a can of worms is now open, perhaps it's a non issue. My sound has been fantastic with the Supreme/A90 combo and the Supreme/Coralstone combo. I use a Foz for azimuth setting.

It may well be a non-issue in practice. With the front-center and rear-inside points touching the headshell along with the two screws, that's four secure points of contact, which is probably enough to maintain adequate rigidity. If the inside screw is tightened first, the cartridge shouldn't tilt when the outside screw is tightened, although over-tightening it would create countervailing pressure, if not torque, on the cartridge body. Any slight tilting could be corrected with the Phantom's easy azimuth adjustment. Still, the idea of one point out of contact bothers me a bit in theory, so I'm curious whether others have taken measures.

Hi bill,
With unipivot bearings, they visually ride the groove different from gimble, quote on quote level heads shell with gimble type arms. You need a fozgometer to get it right with a graham, IMO. So even if the mate between cart and head shell isn't exact, you will correct that anomaly via Foz azimuth or o scops, graham head shells tilt inward by 2-3 degrees from vertical, ime
