I just purchased an old Nakamichi MC 1000 which is recently
(30/03/16 ) re-tipped by Expert Stylus&Certridge Co, with
Paratrace stylus in the existing beryllium cantilever. According
to the bill the re-tip includes examination of the coils and suspension
as well the removal of magnetic particles around the coil former.
The work is perfectly done but the price was 268 GBP. The boron
pipe is similar to the beryllium pipe and both are superiour to other
kinds of cantilevers ( see Fleib about cantilevers in the MM
Thefile, I agree with Nandric. The boron pipe can not be replaced with its equal, and any substitute will most likely be inferior.
It might cost more money to retain the original cantilever and have it retipped rather than a rebuild which replaces it. If you wish to retain the original performance, have the same type (as original) stylus as a replacement. This is one area where I would consider an upgrade. If it had an elliptical tip I would consider a line contact or micro, but I'm not familiar with your Supex to make such a recommendation.
Thank you Fleib, I am going to ask about using my Boron pipe. I have owned many cartridges in my time and I just got lucky with this Supex, cartridges that cost 3 and 4 times as much. Just so you know the Supex line was made by Sumiko. Nandric had mentioned to check your thread on cantilevers but I cannot find it, is there any way you can put in a link so I can read it, I would be interested.
Axel Schurholz in Germany repaired my Technics EPC-100c mk3, new boron cantilever is no problem for him if you don’t mind boron rod instead of boron pipe. He use Nagaoka boron cantilevers as far as i know.
Look at this picture of the new elliptical tip on boron cantilever of my Technics EPC-100CMK3 (retipped by Axel). Sounds great!
I’ve owned two cartridges with sapphire cantilevers: ADC Astrion (i wasn’t impressed at all) and Argent MC500HS (high output MC which i like a lot!).
Nothing wrong with alluminum cantilevers if the nude well polished diamond pressure fitted like this Denon 107 i have sent to a friend.
It’s all about the balance, not the material used in cantilever alone. You can lose the magic of your cartridge replacing cantilever from alluminum to boron or sapphire. Some of the vintage cartridges with alluminum cantilevers sounds amazing in original form.
Thefile, Actually Supex was probably distributed by Sumiko. It was the predecessor to the Koetsu line.
The cantilever info Nandric was referring to is buried somewhere in the MM thread, the one with 12K + posts. A tube cantilever is more rigid than a rod if the diameter of the tube is larger than the cross section of the rod. Boron tubes are no longer made. Sometimes performance is degraded with a substitute, although I don't know if this is the case with your cart.
I don't think you could go wrong with a retip without a new cantilever. The only question would be stylus type.
Dear @thefile : Boron pipe?, has no substitute. The boron rod is really diferent, today exist no more boron pipe cantilevers. Beryllium is diferent too.
Now, what you need is only a stylus change using the boron pipe cantilever on your cartridge. Here who can help you about:
