What is the life of a Grado Wood cartridge?

I spoke with John Chapis,chief engineer of Grado and I asked him how long does a wooden cartridge last.He stated well you've got 2 minutes to talk to me.How does 5,000 hours sound to you.It all depends on the care of your vinyl
and the use of a stylus cleaner.If you use clean records
it should last you a very long time.
I spoke with other dealers who stated it should be changed before 1,000 hours due to the inward parts detereating over time even if the cartridge is not being used.
What is the coorect answer? Was John just trying to sell me his top of the line cartridge,or was he just giving me an answer I wanted to hear?
I'd go with Chapis. A thousand hours is ridiculous. And as far as "deteriorating over time" is concerned, my current favorite MM cartridges date from the 1960s and 1970s (ADC XLM and Sonus Blue) and sound fantastic. The dealer just wants to sell cartridges, though I give him credit for at least carrying them! Good luck, Dave
I would respectfully disagree with the above. The Grado should not have an appreciably different life than other cartridges. We have been aroung this tree many times, here is just the most recent thread. http://forum.audiogon.com/cgi-bin/fr.pl?eanlg&1113190885&read&keyw&zzcartridge+life
I am amazed that someone would respecfully disagree with the chief engineer at Grado on how long one of "his" cartridges last. This is of course based on cleaning your records and stylus on a regular basis.
So do you think that the chief engineer of Grado does not know what he is talking about? But maybe you have the kind of credentials that Mr. Chapis does, I don't know you, so I apologize for my ignorance if you do.
If you don't, and after hearing what Mr. Chapis' take is on cartridge life is, aren't you the least bit interested in talking with him to understand how he comes up with his conclusion of 5000 hours?
If Mr.Chapis states his cartridge last that long I will take his word for it.I just wanted to hear it from the engineer's skillful hands.WHAT HE SAYS IS THE GOSPEL TRUTH.
Actually I was surprised to talk with him directly.He seems
like a very frank and candid man,and I'm happy he's still with the Grado company.
Mescabo, did you bother to read the referenced thread? If you did, you would have all of the answers that you need. 76doublebass, if "WHAT HE SAYS IS THE GOSPEL TRUTH", then why did you ask "What is the coorect (SIC) answer?" Is it that you need validation? If so, you won't be getting it here. Incidentally, no where do I read that John Chapis - who I have spoken to, having owned three of the Signature line, though not discussing sylus life with him - said that a cartridge would last 5000 hours. If you are quoting him directly, after dismissively offering you two minutes of his time, he threw out a question, "How does 5000 hours sound to you?" A question is not an answer. He does answer though with, "...a very long time." Sorry, two minutes does not constitute a serious discussion on the subject nor does your description of the conversation indicate that 5000 hours is the expected life of the cartridge.
Chill out, Have a beer and relax.iF i gave the impression I was attacking the honesty of Mr. Chapis I did not mean to infer that.I was just trying to bring out the differences of opiniion from what a dealer said to me and what was stated by Mr. Chapis ,thats all. Enjoy the music, I will too.
Domestic or imported?
Dopogue.A little off topic here but Holy Tamoli man! You still have an original sonus blue that didn't suffer from stylus fatique? That is truly a revelation to me sir. The sonus blue was my all time favorite mm cartridge with a high frequency reproduction that was the best I have ever heard period... bar none. Mounted in a black widow tonearm it tracked like a thoroughbred and was dead quiet to boot. Unfortunately... I went through 4 of them and none of them lasted more than a couple of hundred hours before the cantilever sagged and simply gave up the ghost. Prior to the sonus blue I also used the adc xlm and still have it in my collection although I have not listened to it in years. To my ears and many of my audio friends as well: the sonus blue outclassed the adc by a wide margin. Unfortunately,everyones sonus blues suffered the same stylus fatique fate in very short order. PS: Bet I can guess your age give or take 5%. Just teasing you a bit here sir.
Ecclectique, I was pretty surprised myself. I had two Sonus stylus assemblies (not the bodies, can't remember why) in my junk drawer and went for a Sonus cart I saw on Ebay about two months ago. It sounded pretty good, but when I substituted the old styli, it sounded just about like you'd expect a 30 to 40 year old cart to sound: dead. So I figured I had nothing to lose by slathering the rubber suspension with some stuff called "Re-Grip," a rubber cleaner and "revitalizer" I use on reel-to-reel tape deck pinch rollers (yeah, you can probably guess my age). The stuff brought the old styli back from the dead and the cart sounds GREAT, definitely better than the ADC. No sign of cantilever sag, yet. These carts definitely love the SME III (mine is damped), by the way. Dave
I do believe the question of longevity of the Grados, like the ADCs and Sonuses, is more a question of suspension life than stylus life (all reports of dead Grados I've heard so far are dead suspensions): the heavier the tonearm, the lesser its lifespan, the lighter the tonearm, the longer the lifespan. I use my Grado Platinum on an ultra-low mass Black Widow for this reason, and Dave's SME IIIS is also an ultra-low-mass tonearm. Stylus life depends on so many factors the spread is probably quite large, from 500 hours to more than a thousand, depending on condition of records, stylus hygiene and so on.
So 2 hours of playing a day would put you at about 1year and 4 months for a 1,000 hour usage.If memory serves me correct my old AT20SL lasted way over 5 years plus.
Maybe we got more bang for are buck back in the 70's and early 80's.Just a Thought.
