Tonearm Advice Needed


I would appreciate some advice on selecting a tonearm.  While new to the forum - this is my first post, I have spent quite a bit of time reading on a number of topics over the past couple of years, or so.  And, while I've had several systems composed of separates, I have allowed myself to become a little stagnant over the years.  So I have "some" knowledge, but I'm nowhere near sophisticated.

I have a couple of turntables, but I purchased another one some time ago. I plan to use it with a new system I am in the process of assembling. The turntable is a first year production TD124 (1) in great shape I bought at a pretty fair price. I did set it up with a mid-level tonearm with a MM cartridge and it was somewhat impressive. Thus, I was encouraged to improve the sound with a nice arm.

Before knowing as much as I needed to know, I put the proverbial cart before the horse a couple of years ago. I latched on to an SME 3009R still sealed in the original packaging.  I've not taken it from the sealed wrapping, since I later thought I may need a lower mass arm for an MC cart, such as an AT Art 9.  I'm considering the similar style SME M3-9R.  I could depart from the iconic style, I suppose.  But the new model may be sufficient - I'm not really sure.  The system I'm putting together so far consists of a Pass X250, Pass X1.  Phono Pre may end up being Pass as well. At the present, the phono is an ifi 2.  I've tentatively set the tonearm budget at around 2K, thinking I could sell the NOS SME to at least partially fund the new arm. I not quite comfortable with a used tonearm.  I'm not married to the whole TD124 thing, but I'm hoping that for the cost of the table and arm I can obtain very high quality sound for the money.  I'm budgeting for new speakers, having lived with 4311's and AR10Pi's for a long, long time. I listen to all genres of music.

When using a LOMC with my SME 3009 II Imp, I use a beefier magnesium headshell (16–18 grams, and also has Azimuth-adjustment). It's much less resonant. Its mass requires more mass at the c'wt end to balance, not too difficult to achieve. The greater mass at both ends loads the knife-edge bearings down more securely. All in all, these simple changes make the 3009 a very good platform for LOMCs from every perspective. It's a very versatile tonearm if you're open to some simple improvisations, and don't consider them "heresy".
Great plan. Perhaps a slate plinth? Anyway there are a number of lower compliance carts that are wonderful and perhaps a well chosen SUT? I have a few LOMC  I like but as a distributor and dealer I won't mention to leave bias aside...
Thanks for all your advice and information.  This, together with a bit more research elsewhere, has convinced me that the 3009R is really a great arm - likely besting many successors from SME and a quite a number of arms from other companies.

After settling on tricking out the TD124 with this new tonearm, I'll be budgeting for a new-used phono pre and cartridge.  I'm attracted to an Ortofon SPU, but I think money is more effectively spent on an alternative MC.  I'm a little concerned about the ferrous platter, but a significant number of MC users on the Mk 1 comment it is likely a non-issue.  I'd like to think more about a DL103 enhanced variety, the AT Art9, Shelter, Mayajima - - once I become more convinced of the compliance issue consideration. 
@ solypsa - - The temporary plinth is an "open" 3/4" mdf with walnut veneer.  I'm a bit surprised at how well it functions - relatively speaking, that is.  I do plan to purchase a new plywood-based plinth, then experiment with alternative mountings of the table.
IMO, the biggest problem we face is set-up. A Koetsu on a Durand, if poorly set up, will be bettered by a well set-up rig in your price range. Therefore, choose an arm which can be precisely set up, and will retain its settings. I set up to parallel within 20 minutes of arc (0.001"), azimuth to within 10 minutes of arc.

If you end up using a suspended table, for which an air bearing arm is impractical, consider Pete Riggle (disclaimer: I have not used his arm, but have used some of his accessories, which are well-made and to specification). Otherwise, if an air bearing is feasible, consider a Trans-Fi, which has all the above desiderata. It is also sold factory direct, for $1000 !!!

I used it on a 10K Nottingham Analogue, upgraded several times, and bought another for my DIY air bearing TT. If I were upgrading (a big if) I would only upgrade to a Durand. For what it's worth.
There's a new boy in town.  Venerable Jelco have put out new tonearms.  The existing 750D (that I run) is an overachiever - I preferred it to an Origin Live Conqueror.  Jelco now have the 850 and 950.  I am considering upgrading.
Before knowing as much as I needed to know, I put the proverbial cart before the horse a couple of years ago. I latched on to an SME 3009R still sealed in the original packaging. I’ve not taken it from the sealed wrapping, since I later thought I may need a lower mass arm for an MC cart, such as an AT Art 9.

Note: I just noticed I made a typo on the tonearm model I’m considering, though most of you already likely understood I must have meant SME M2-9R, at 9 g effective mass, and improved ball races, etc., vs. the early production 3009R at 12.5 g. effective mass with nylon bearing.
Hi @ nolojunko,

By the numbers, a 9-ish gram effective mass arm is a reasonably good match for your AT9 which is specified at a fairly high compliance for an MC of 18×10-6cm/dyne.

A large majority of current MC’s are in the 12-15 range and vintage ones can go down into the 6 range (very low compliance).

Numbers are just that however, and you’ll find (for example) that subtle changes in effective mass can significantly change the character of the cartridge.

I relate my experience with arms that have multiple counterweights (Durand, Tri-Planar, Moerch, Kuzma) which allow you to use lighter weight combinations (farther from the bearing pivot) or heavier ones (closer to the bearing pivot) to achieve the desired tracking force.

The actual change in effective mass is very subtle, but the audible change in presentation can be quite dramatic, depending on the cartridge.

Results from the few arms I’ve played with which have sliding weights along the arm tube yield even more significant results as you’d expect.

I think the bigger question for you relates to whether you’ll find yourself liking the AT cartridge. If you don’t for some reason, you may be locking yourself into fewer choices down the road - trying to source a high compliance MC to match your tonearm.

I like to think of cartridges as a consumable item (much as we don’t like to) and to approach this from the tonearm perspective - matching a cartridge to the tonearm rather than the other way around.

The safe bet (given the current range of cartridges) is to source an arm with an effective mass in the 11-12 gram range.

Having said that, none of this is an absolute, and I don’t mean to strike fear in your heart over the SME / AT combination.

Cheers,

Put another way, my SME 3012R surpasses my $6.5K Kuzma 4P.  Those R-series SME arms were magnificent.  Be confident enough to unwrap yours and try it prior to hasty resale. 
Ditto. If you take the 124 / SME you have and select a cartridge to match it (there are plenty) you will have a superb analog front end. What plinth is the 124 in?
Keep what you have.  You need to spend big dollars to make a substantial improvement
Note:  I just noticed I made a typo on the tonearm model I'm considering, though most of you already likely understood I must have meant SME M2-9R, at 9 g effective mass, and improved ball races, etc., vs. the early production 3009R at 12.5 g. effective mass with nylon bearing. 

For those of you who have run (or are presently running) a 3009, is it a lower mass version, such as the improved?

Another question: Is the significantly lower mass and improved ball race engineering worth the additional investment in terms of higher compliance cartridge options, performance, and SQ?  

And, would anyone know the market value of a mint NOS 3009R should I end up being convinced other tonearms would be quite a bit better on this setup?
An ART7 (with compliance similar to ART9) works well on my SME 3012R.  Keep the 3009R. 
Regarding speakers: the venerable Quad ESL 57 is STILL a world-beater! I myself have two pairs awaiting setup (bought my first pair in 1981 - kept them in use for 19 years before stupidly selling them!).
I too have owned and enjoyed using the 3009 with mc cartridges on my Ariston RD11S (the Sondek's Scottish cousin). It has sufficient mass to work well with a variety of mc cartridges! Keep it and spend the money on a world-class mc: the Miyajima Shilabe ($2800 new, less used). Check out the review on Dagogo!
I'm no arm & cartridge expert, but many mc cartridges benefit from not a lower mass arm, but a higher mass one. It has to do with the compliance of the cantilever, and the resonance resulting from the combination of that figure and the arm's mass. The SME 3009 is, I believe, a medium mass arm, and may be fine with the Art 9. I had a 3009, mounted on a Thorens TD-125, and loved it. A 3009 on a TD-124 is a classic combination!
