Refurbished / Re-tipped Cartridges - Are they worth Buying?


My thoughts around rebuilt carts, do they convey the same characteristics as the original designer envisioned and intended . Even with full restoration like new cantilever, stylus and suspension repair etc; much of the original design attributes are gone and you are now listening to the works of an individual who have pride themselves as rebuilt wizard.  

No disrespect intended for the folks in rebuilding business as I honestly believe they are incredibly talented to rebuild such a fine instrument. 

What are your thoughts, would you buy a completely rebuilt cart vs a slightly used cartridge….after all you’re mostly paying for brand pedigree, its signature sound and exotic materials to make such a fine product.

My thoughts against non-manufacturer rebuilds / retips have softened somewhat over time - of course partially out of necessity, with more old masters passing on (more reports to come in the next several years, I’m sure). At some point I’ll need to have a Koetsu rebuilt by 3rd party (had a few rebuilds done by Koetsu) - and that’s OK; life goes on. I’ve seen a couple 3rd party rebuilders using what looks like the exact same Japanese-sourced cantilever and stylus assembly used by Koetsu, and these should be a strong consideration (Ana Mighty Sound in France, Sửa Kim Than Cartridges in Vietnam). That said, I probably wouldn’t mind a Fritz Gyger on boron either. Groovetickler in USA also seems to do great work. Also check out "Delta667" on the vinylengine forums. He is a true fanatic in exploration of cartridge design & rebuilding! There is so much to learn from the massive "Cartridge Close-Ups - Show Your Shots!" thread, and people there even get along!

Once you replace original parts with something different, you go down the road of making a hybrid, and the spectrum of "good, but different". So what parts matter? Ortofon’s Kontrapunkt and Cadenza series (Kontra being the predecessor of Candezna) offer an interesting exploration into this question - each line had 4 models with basically the same motor generator and body (with some minor differences), but featuring different combinations of cantilever and stylus. Given my experience with these models, plus experience with different Koetsus, I’d place the magnet type and then cantilever material as having the highest sonic impact. Next is body type. With various Koetsu stones being very similar - that differentiation is more subtle than outright changing body material types (like from wood to stone or metal). Coil wire and stylus - I’d rate these as more subtle changes to the sound.

Of course the coil (windings and armature), damper, and yoke arrangement probably have largest impact on sound, but that is probably harder to isolate for a controlled comparison. I had a vintage Koetsu Onyx (non-platinum) rebuilt by Koetsu, and it sounded quite different - both to how it sounded before, and next to a modern Onyx Platinum. The older coils sounded more lush and "romantic".

lalitk, You don't need the original designer to replace the cantilever/stylus assembly with parts identical in physical characteristics to those of the original.  The question is whether such parts are still available, if the cartridge is very old.  For one example, one of my favorite cartridges, the B&O MMC1, came with what appeared to be under my microscope a hollow tubular sapphire cantilever, and if memory serves, the stylus was inserted across the hollow tube without glue. (I am relying on memory, because I accidentally tore the cantilever out of my MMC1 while trying to engage the built on stylus guard.)  The replacement, done by Soundsmith because of Peter Ledermann's expertise in B&O, is a solid sapphire rod and a glued stylus, with a very visible gob of glue holding the stylus in place.  Not at all "like new". And yet, not cheap.

Dear @lalitk " would you buy a completely rebuilt cart vs a slightly used cartridge…"

 

Completely rebuilt... certainly not and slightly used cartridge could depends of its " vintage " because normally designer/manufacturers of cartridges over short time makes small/tiny changes in the same model with out knowing the market/customers and they did not advertise about because some of them think that the changes do not deserve a MK2 version or the like. In the other side if the owner put on sale because he now own a better cartridge model in the line or even a different top rated cartridge could be worth to buy that slightly used cartridge when normally you can buy it for the 50% of its retail price, sometimes even with higher discount.

At the end everything depends on each customer, in my case I’m out to buy any new top cartridge or slightly used because my long first hand experiences already fulfill my cartridge expectations and I know for sure that speaking of today top rated cartridges in reality several of them are not really better but different or only in one quality performance level characteristic is better.

New top cartridges are only " new models " but at the end it’s more of the same. The only example I have of a new model are with the Lyra Lambda SL that in true has better differences not only against its past lines but against the competition.

I listen briefly the Fugga ( this is only an example of what I’ posting ) and not in my system but I owned the original Miyabi and listened the 47 and my vote go for Miyabi. Btw, today is weird that with a " top " cartridge with high price label the designers had better options that aluminum in the cantilever and stylus shape but they took the Miyabi road in this regards.

Always had excellent experiences rebuilding carts with Soundsmith. Re-tip with or without new cantilever. However that is starting from an original cart. I would not buy a used rebuilt cart. No way to know how they were handled and how much use they got.

I think a distinction must be drawn between retipping by sawing off the cantilever and glueing a new cantilever/stylus to the stub, and retipping by leaving the original cantilever intact and replacing only the diamond stylus. In the former, the mass of the moving system, and the resonant characteristics of the cantilever are altered. In the later not so much, if at all.

Now some cartridges, Lyra and Koetsu come to mind, have proprietary stylus cuts, so those will never sound exactly the same, but most stylus cuts are generic and supplied by Orbray, Ogura, Geiger, and a few others.
