I recieved a audio-technica AT-OC9/III today and mounted it on my Clearaudio Concept.I owned the OC9 version 2 a few years back and wanted to hear the version 3 for a while now.Anyway, great sounding cart as always.I think version 2 tracking was 1.5.The new is 2 grams.Version 3 also uses Boron materials.

So how best would you describe the sound from the OC9/III with your current setup compared to anything else you have used in the past regarding MC or MM carts?

Thats a hard question for me to answer.I have several tables and all have MM carts and I have always been a fan of MM carts.It's my preference.I have tried several other MC carts before but always came back to MM.I always had a soft spot for the AT OC9 becuase of the bang for the buck and I just dig the sound it produces.The cart it replaced was a Clearaudio Maestro MM.I can't say definitidely is one is better than the other.I am looking foward to some more breakin with the AT OC9.The Maestro is twice as much as the AT and that I can't tell which is better makes the OC9 a great value in my eyes.Fortunately my Musical Surroundings has dip switches for the gain and load as the OC9 is low output.So, my main turntable I will use both the Maestro and OC9 and probably switch off from time to time.In my mancave I have 5 TT's all with MM carts.Grace 9E and 9L,Shure V15 IV,Shure V15 VxMR,Clearaudio Concept MM.

Can you give us an update of your opinion of the OC9-3 cartridge? I am looking at buying a new one, and this is on my list of possibilities. :)

Looks like Scotty was beamed up. I've been thinking of buying the AT-OC9ML/ll myself and been curious as to how it compares to the Denon DL-301mkll I'm presently using.

I'm very curious myself. Never been a fan of AT and I got a general phobia of MC carts. My wife got an Ortofon Rondo Bronze for which we're still paying because we had to upgrade our pre-amp and get a proper step up. I'm not sorry but now we've got too many turntables (five actually - all of which are variations of the Thorens TD-160) and I need some good carts. I was thinking, naturally for me, about the Ortofon 2M Bronze or Black. I wonder how the OC9/III compares???

The OC9/MLIII is a clear step up from the 2M Bronze and a Concorde with a 40 stylus (basically an om40). More detail then either of those, wider/deeper soundstage, and less surface noise. It's also the best tracking cart I've ever had.

I know the MLII was accused of being overly bright but I can tell you the III is not in the least.

I will go for it just on account of this reply because the rest of the answers I got all over the world are illusive and lame and introduce more variables into the formula rather than attempt to solve it.

The 33EV is a fine choice as well - do some reading about both and decide which "sound" you are after...

Yes, I also took the plunge and bought an OC9-3, after asking about it above. I then bought a Threshold Fet-10e phono preamp. (about $700 delivered, EBay) The combination of the two is jaw dropping. Iíve never heard any of my vinyl sound this good. I think the proper MC transformer will do away with the extra back ground noise, which IS a little bit audible, and give me an early entrance in to audio heaven.

What kind of step-up are you using? Iím very interested to know that. Choosing the right one without being able to audition them can get complicated. There are varying opinions on whether they should be resistance loaded etc. Right now, I am looking at the Rothwell MCL.

At that price (700) you got just the phono stage .. ?

You have my condolences. This might make you feel better. LOL Years ago, I bought a bunch of gear from defunct Musicraft in Oak Park, Il. He hand selected a Shure V15-5MR, and I took it out like a dumb-ass to look at it. I had like a nervous reaction or something, and almost dropped it. I snapped it off right in front of the salesman, AFTER I paid for it. Had to buy a new stylus for a new cart.

ETA: The stylus protector on the OC9-3 SUCKS. To put it on, it's like you are risking wrecking the stylus by the way that the, "Protector" goes on to it. They should rename it the stylus destroyer. LOL I also just bought a Grado Ref-sonata, used, and the protector on that is very well implemented. I also still have a BP-Evo-3, which can't be fitted with one. The stylus on that sticks out as if it is asking for it.

Hate it when approx. $600 goes POOF...It was really because the damn connectors are so tight..was using my usual special need nose pliers. Got to the last connector (they were all tough)...SLIP..UGGGG.

I wish these companies would spend an extra 5 bucks on the connectors I got when I bought my litz wire kit ! They go on easy, snug up, and come off easy. These :

Arcorob: Well, if you are moving to an AT33EV, then that should compensate a little bit. I'll be interested to hear your impressions once you get it going, esp in how it compares to the OC9's. The AT33EV has a very good stylus protector, I think, so there is that.

I am kind of hoping it IS a clone of the AT33PTG from Japan. I really liked the sound and soundstage of that one...just couldn't seem to make it LAST (long story)

I am hoping I did the right thing. I could have gone with another OC9..but I figured what the hey..

Actually there is a cartridge retipper in Seattle you can take the OC9 III to. Website is phonocartridgeretipping.com Andy repaired a coil and retipped a Clear Audio Signature cartridge for me, which another retipper declined to attempt. Andy will get all of my retipping business when practical. Its worth a shot for you, believe he is in Bellvue.

People I know who have had the PTG and the EV felt that the EV was a step-down. A few have reported it can have tracking issues that the PTG didn't. This is all second-hand info so take it for what it's worth. By all accounts, though, it's still a phenomenal cart. Very sorry for your loss on the OC9

the OC9/MLIII is a better cart then the 33EV. It tracks much better, is more detailed, less prone to rfi and quieter in the groove.

That sux big-time, like the time I destroyed a new O'fon MC-3 setting it up. With the OC9MLa/II in the Mitz LT and a DL-110 in the mod'ed PL-L1000 I'll likely never miss it other than the lost potential playing time on a nice stone.
AFAIK the '33EV has a nude elliptical stone on a tapered alu tube, nice enuff but the PTG a nude ML tip on a gold plated Boron cant. Pretty significant step up.

I haven't had the OC9 or the PTG, but I can say with certainty that there are no tracking issues with the 33EV -- not sure exactly what that means, actually, but it faithfully plays what's in the groove, and handles warps better than any cart I've owned. It's also the quietest cart I've ever had in terms of surface noise.

In some literature from Japan/AT, they referred to 33EV stylus as a MicroLine Elliptical. In other words, there are ellipticals and there are ellipticals. For example, a Grado Gold claims to be an elliptical, but I am certain it is nowhere near the cut of the 33EV. Also, some people who have had both said the 33EV is more forgiving of less than perfect vinyl than the PTG.

The comprehensive review I read on the 33EV that convinced me to get it over the OC9-III said it was a substantial step up over the OC9 in every way. People hear "aluminum cantilever" and think it must be a step down from a boron, but it is not just any hollow tube. A very small, hardened, tapered aluminum cantilever can achieve the same design goals as a more exotic material. In short, the 33EV is a very fine cart, and I believe you will enjoy it immensely. And based on your experience trying to get a PTG, I can understand you not wanting to go down that road again.

I did some research and I believe the AT33EV was their way of bringing the Japan only AT33PTG to the US and UK.

I really like the PTG ..slightly better than the OC9. Loved the OC9 so you can imagine. Its funny, some sites say the EV is a ML, others an elliptical. AT says elliptical.

In terms of who is on top, they say the OC9/III is their flagship...2nd'ed by the 33EV. I'll see..if I don't like it, I can return it and get an OC9.

Or

I did some research for possible upgrading and the relative ranking of the two MCs seemed mixed depending on the reviewer, deeply-discounted price of the discontinued OC9/II ultimately drove my decision as an irresistible price-for-result bargain. This cart's gold plated Boron cant' may be responsible for it's natural and well-proportioned upper-end response lacking the usually-expected MC top-end 'sparkle'.

I'm pretty sure the suspension on these carts (and most carts like it) is a hair-thin piece of wire. You'd think Soundsmith could repair it, since you would think it's part of every cantilever they replace(?).

On another topic, what is the advantage of gold-plating a cantilever? I thought the most desirable characteristics of a cantilever is lightness and stiffness -- gold is neither, being soft and heavy. Just wondering. I'm sure they have their reasons.

Man, did you catch the prices on those new AT carts? One of them was twice the OC9/III/AT33EV/PTG, which are all very close in price. The ART7 has a list of $1200 (120,000 yen). Maybe that means we'll be seeing it over here for $500 soon?

Gold is infinitely malleable (does not work-harden) and has high weight-to-mass ratio. A thin coating effectively damps bending/wave resonance modes on/in the already-quite-rigid Boron cant'.

I've read that the gold isn't really plated on the cantilever. It's vapor deposited for a super thin coating.

The link above to the ART7 says it has air core coils like a DLS1, hence the ultra low output.

I'm surprised no one mentioned the PTGII.

The link above to the ART7 says it has air core coils like a DLS1, hence the ultra low output.

I'm surprised no one mentioned the PTGII.

Hi I have not seen you post in sometime. I like new avator pic of the SS.:thmbsp: Last time I was over did you have the OC9M/II playing? I have been looking at a AT-OC9/II or a Denon DL-301 Mk III and see if the MC sounds better then my Pickering MM. I can get a OC9/II for a little more then the hard to find NOS Pickering stylus I use.http://www.lpgear.com/product/ATC01.html

Somehow I think I should have went for the AT-OC9 MKIII instead of the MKII I purchased for $100.00 less. Perhaps even the AT33PTGII, but I hear they have their own set of suspension problems.

I do want to keep the AT-OC9ML/II until the AT-OC9/III breaks in...I estimate about 50 records because then I want to do some comparisons but it really wont be a fair comparison since the MLII it about totally worn out. It's been played hard for over 6 years now and I am pretty sure it has well over a 1000 hours on it and its beginning to sound raspy.
But yeah I can let you borrow it for a while.
At the moment as the AT-OC9ML/II is being phased out LP gear is selling the MLII for an insanely low price "While supplies last"

Maybe:scratch2:
Depends on what he charges the MLII has a microline stylus.
May want to contact them and see what just a retip costs the cantilever is still good but the suspension may be questionable since is is now 6 years old.

I wanted to go with the III because it loads at 100 ohm because my phono stage is a fixed 100 ohm thought it would be a better match than the 20 ohm loading the MLII requires

I have been impressed with the OC9ML/II since I got it for $294, it is not past 30 hours yet.
I also do run it at 100 Ohms with an active phono pre. Quite nice!

The Denon DL301/II is nice too but not as detailed as the OC9ML/II.

At Comet Supply prices of $212 delivered for the Denon 301, it is also a steal, but you have to contend with the wait.

I have a Technics stand that sets the over hang I used to hold all those vintage carts Pop had that I sold here last year.

Well I just completed the 52nd album and pretty sure its as close to being broke in as it will get...(though I could still be in for more surprises)

Is it an upgrade over the MKII?
Yes!
Is it knock you over with a feather different?
:scratch2: Not exactly.
It does still have the classic signature sound as the MKII, its lightning fast has plenty of air with lots of detail and a wonderful soundstage.

Where the MKIII differs is where the improvement is. IMO
wider soundstaging, slightly warmer sound (a bit less bright), vocals are better focused less edgy, midrange has a bit more depth, deeper bass, a bit less surface noise.
Seems to dig a little deeper into the grove uncovering subtleties that the MKII just could not quite pick up.

With the discontinued MKII at the bargain basement price being offered at LP Gear that is "while supplies last" and those on a budget or not I can still highly recommend the MKII.

And for those that are MKII owners looking for an improved OC9 I feel that you will in no way be disappointed with your purchase. :music:

Just how does the suspension/damper work on the MkII? Does it have a hollow canitlever with a fine wire inside to keep it from bowing? IIRC Pop's vintage ADC XLM had rubber inside the cart body that the stylus went into and dampened the cart. :scratch2: I was told if a MKII starts to mistrack and has to have the tracking weight at the 1:75 max the supension damper is going bad.

The ADC is a "free-pivot" cantilever cart, the cant' wiggles about an elastomeric suspension ring at it's center see-saw style and the ring constrains it somewhat. It does not have a rigidly defined pivot point per se. The O'fon MMs are also free-pivot types.
The MCs like the A-T are pretty much all fixed/defined axial pivot types with an axial tie wire from the end of the cant' to a fixing point on the cart thru a platform coil former that is seated onto an elastomeric suspension ring. Audio Technica MMs and Grado MIs also have an axial tie wire defined pivot with an elsatomeric suspension ring.

So the At MKII is a soild cantilever with a wire from the end of it that is conncted to a elastomeric ring inside the cart? I will Google this and look for a link with a diagram. Old retired Tool & Die maker, I need a print to look at. :yes: Thank You.

The wire is usually tied to a 'hard' fixing point in the magnet pole for an MC, into the stylus frame base on the MM/MI types, some pix.

Now here I am 30 odd years later and going thru 800 or so old vintage records of different thickness and speeds. I purchased a mint used Spin Clean and found a NOS stylus for Pop's Pickering cart and cleaned up his old Pioneer PL-518X and with to vinylengine and learned how to to use that damn Stevenson 2 point null protractor. And started to clean/ vacuum and play a few 33 1/3 Lp's every day now. Now I see why some of the members have several TT with different carts/stylus for those old 16/78 RPM etc.
Big fun :music: but now I am getting the "Bug" to try a MC cart and upgrade my analog gear as I have had Pop's Revox R2R restored(thanks to TINMAN) so I can record some of these LP's. Thank You for the info and those pic's.

Well I got my First taste of a MC cart yesterday. I went over to Autobots with my my 34 year old Pioneer PL-518X TT and we spent the day installing his used AT-OC9ML/II. WOW :music: It sounded AWSOME on this old "S" arm TT. But he has some really nice analog equipment to boot. He was suprised how nice my MM Pickering XUV/D4500Q (Shibata) combo sounded. But after a hour of instpecting the inside of Pop's old Pioneer and setting up the MK II MC cart............ WOW just WOW I played several of my best sounding LP on it that "KNOW" how they use to sound. MUCH more detail. Monday I will hook it up to my crappy AVR and try the Denon step up LC-OFC step up unit AU-300LC Autobot loaned me.

The new run in (50 LP's played on it now) MK III is BETTER then the MKII. His MK 5 GM TT and his NAD/Crown set up is SOOO detailed. I came home 9 hours later with my ears still "Ringing" and Big :D on my face. I am HOOKED on MC carts now......... time to spend some $$ , next months SS check will take a hit for a adjustable MC phono pre/amp. Thanks Autobot. I had Big fun with the MM VS MC cart tests. Oh and Man your SS Camaro is FAST.... what a RUSH, this old man went home (in wifes KIA) wishing I had NOT sold my Corvette several years ago.:tears: well you opened my eyes and EARS to the MC cart sound.

I am Really suprised how much more detail this AT MkII cart MC sounds on a this vintage "S" arm DD semi auto consumer Pioneer TT. I have read so many posts about you need a expensive tone arm and a TT that has a tone arm you can raise up and down to adjust VTA, etc etc. One of the reasons (other then cost) I never purchased a MC cart..

My TT is 25 feet away from my Yamaha receiver so I had to use a diigital input and I purchased a TCC-750 MM phonoe pre for my Pickering. Now I am going hook my RCA cable back to the phono input (MM) and plug it into a Denon LC-OFC step-up transformer AU-300LC and see how the MKII MC cart sounds.

I think Autobot will swap me a Yamaha adjustable MM/MC phono pre/amp for a Akai R2R I have ( I own several) to see if he likes analog R2R If not(R2R is not for him) they are both on loan until I can purchase a nice seperate amp and phono pre/amp and get away from my HD AVR.

Thanks Bro. Me TOO. I did as you advised I hooked up the Denon step up transformer to the back of my Yamaha receiver MM phono input and grounded it and ran a ground wire to the TT 25 feet away and hooked it up this way.much better then the Denon SUT next to the TT as I got a hum at 50% volume that went away when I reveresed the hook up.... I was bummed out until you emailed me to try the way I have now :thmbsp:

The AT-OC9ML/II is playing Great this way.No hum. Wihout a MC pre/amp( I did run a long ground wire from the Denon to the TT)............... When I had the the Denon next to the TT and the cables to the AVR MM phono input I got a hum at 50% volume. I know this sounds wrong ... no MC pre/amp... in the mix but this Denon is working when hooked up to my MM phono input on my Yamaha AVR I use for our HT system.:scratch2:

I am saving up for a nice MC pre/amp and nice stereo seperate amp. I/ we watch a lot of Bluray movies our HT system needed HDMI etc I whored out and got HD AVR for a Pre/Pro and was suprised how nice it's amps played my 5 Klipsch speakers in my super small den so I did not purchase a seperate amp for the HD AVR.


When I had my Pickering XUV MM in the TT I used my TCC-750 MM pre/amp next to the TT and ran the long RCA cables into a digital input on my AVR and it sounded good (no hum) 12V battery, wall plug sucked when the volume was up..

When I moved the the TT so far from the AVR I l looked at the Art DJ that had MM/MC and passed thinking I would never spend big bucks on MC cart..never say never. Autobot gave me his AT-OC9ML/II as he just upgraded to a OC9III and he loaned me this expensive Denon AU-300LC and said try it hooked up to your AVR phono input and see if it plays.IT does and it sounds great... but if a $50.00 ART MC pre amp and those video cables is a cheep up grade from how I am playing LP's now I will spend the $50.00 or so until I can spend a LOT more for a real MC Pre/amp and stereo amp and have two systems in the den as I am really getting back into spinning vinly again. My late dad left me 900 or so LP to clean and play :banana: long Hot summer here in texas so i am havin big fun when the wife goes to work and I am home along to crank it up some.

SORRY for the thread jack but this is about a OC9 MC cart :-)

Now we need to get you a suitable amp for a music-only system based on a pair of the Klipsch, probably the Cornwalls.
Are you electronically "handy"?
Will respond to your PM shortly----.

I can solder two wires together :yes: I need a new iron or one of those cool soldering stations with vacuum tool. Chased down a few shots in motorcycles and old Hot Rods. Retired machinist/ Tool&Die maker so I can follow a blue print if I have a chart to figure out what some of the electronic symbols are. I helped Pop build a Heath Kit receiver in the 60's so it's been a few years.

Thanks for info in PM I am reading this article learning about the Denon AU-3000LC-OFC MC Step-Up Transformer I have hooked up to my Receivers MM input to my TT as it has less hum this way vs the Denon next to TT. I wish I my TT was not so far away from the Receiver. I am saving up for a seperate amp and pre/amp with MC phono stage and run two system to my Cornwall speakers as they are fronts in my HT system. I am looking at low capacitance RCA cables 20 feet long from your link at Monoprice or Markertek until I can add second system for analog in the mix.Your Pio1980 PIO= "Paper In Oil" caps? Or Pioneer? :D

How does the Audio Technica AT-OC9/III compare with the SAE 1000LT or 1000E?
Thanks

The magnificent monster receiver, I was given one in pieces a few years ago and finally joined AK to get tips on dealing with it. About oily paper capacitors, they seem to be making a comeback with some a'philes after being eclipsed by polypropylene plastic film types. I have some decisions to make about their replacement in some vintage McIntosh tube amps that I'm refurb'ing for an elderly a'phile.

I'm told it's a better cart than the NOS vintage SAE by someone I trust.

I had Pop's vintage MX110Z and MC2125 McIntosh tubs separates many years ago that was fried in a lightening strike :tears: we were lucky the house did not catch fire. I have seen some of Terry DeWicks work WOW he makes them look new. I had a SX-1080 when I got my Cornwalls in 1979 they sounded Great, I wish I had not sold it now. But it help finance buying Dad's McIntosh tubes back the 80's. I sure do like the AT-OC9ML/II cart:music::thmbsp:

I'm quite taken with the OC9/II in the VPI/ET rig.
I'd considered Terry but considering the waiting period vs the guy's age, the shipping, and the expense, I've set up a work station in his bedroom where the wall-o'-McIntosh resides with his self-built custom tower speakers in his penthouse appt where he can watch and we can chat. I've got the C24 preamp done and moving onto a needy MC240, then the MC75s and MR71 tuner. The TT is a Thorens TD-125 w/SME 3009 arm and Stanton cart tho' he isn't interested in getting that working again at this stage of life. Downstairs in the Grand room a needy MX110 tuner/pre awaits with a pair of Altec theatre amps where the 1925 Chickering/Ampico model 'A' full-expression reproducing grand piano holds court. Heard it play the famous Gershwin "Rhapsody in Blue" for four hands roll cut by the composer himself. Magnificent!
It's a 200-odd mile round trip for me so I am having to parse the sessions out somewhat.

WOW he sure has some nice vintage equipment. I wish I had the TT and SME arm. I just purchased this Yamaha A-1000 amp and pre/amp that has adjustable MM/MC and the seller lives a few hours each way from me and he re-capped it etc.
It will do until I can afford a better phono stage and seperate amp. I am away from my HD AVR for analog now. I need a A/B speaker switch for my Cornwalls now. Two separate systems in the den. Autobot has a Yamaha phono stage like this without the amp and it is quiet. Will see if this will do for awhile until I can save up for a nicer rig for the OC9ML/II. My TT will be two feet away for the source now :thmbsp: no more SUT and long cables and the slight hum I am dealing with.

The Yammy amp shouldn't suck, IIRC Mac dealers sold Yamaha as a budget/starter/affordable alternative. I have one, a CA-600 with the older Scandinavian-clean style that presently isn't in use that I found at a flea market.
