Pani ... New ART-9 up and running ...


The Cartridge arrived and I took it down to Studio City to Acoustic Image to have Eliot Midwood set it up properly. Eliot is the bomb when it comes to setting up the Well Tempered turn tables correctly.

So, last night I had Mr. Golden Ears over to get his assessment as well. For a brand new cartridge that had zero hours on it ... all I can say is WOW! This is one naturally musical cartridge that doesn't break the bank. Its everything I liked about the OC9-mk III, but it goes far beyond the OC-9 in every respect.

In a previous post, I talked about the many mono records I own and how good the OC-9 was with the monos. Well, the ART-9 is on steroids. Just amazing on mono recordings.

At under $1100.00 from LP Tunes, its a bargain. The ART-9 surpasses all cartridges I've had in the system before. That would include Dynavectors, Benz, Grado Signatures and a Lyra Clavis that I dearly loved. In fact, its more musically correct than the Clavis. The Clavis was the champ at reproducing the piano correctly ... the ART-9 is equally as good in this area.

Sound stage, depth of image, left to right all there. Highs ... crystalline. Mids ... female and male voices are dead on. Transparency ... see through. Dynamics ... Wow! Low noise floor ... black. Mono records ... who needs stereo?

Your assessment that the ART-9 doesn't draw attention to itself is dead on. You just don't think about the cartridge at all. Not what its doing, or what its not doing ... its just beautiful music filling the room.

Thanks again Pani for the recommendation. I'll keep posting here as the cartridge continues to break in.

Your arm is 10-11 grams according to vinyl engines specs.

About the same as my VPI 3D arm which sounds glorious with the ART9.

Technically if if you go by the calculations, you are slightly below the line for resonance but it’s difficult to know for sure because of the 100hz spec that AT provides.

If you’re worried I’d use the lowest mass mounting hardware you can find.


Thanks for the input; I actually found the mass of the arm at 10 to 11 grams too.

It’s too bad the ART9 doesn’t have tapped threaded mounting holes so that short/lighter screws could be used. I suppose aluminum mounting screws would be a good option

I just looked up the specs on the AT15ss and it's 8 grams mass vs. 8.5 grams for the ART9.  It sounds from what you are saying, I should be trying to work with a mass which is lower; more towards the 8 grams or less.
Yes if we look at the typical numbers, a lower mass tonearm would get you in the sweet spot.  That said my combination is about the same as yours and it sounds infinitely better than any setup I’ve had yet, including some combinations that fell right in the sweet spot.  
For my set up to hit the sweet spot, what weight cartridge would accomplish this?
The change in cartridge weight won’t impact it as much as the tonearm mass and cartridge compliance. Honestly this combo puts you right in the low end of the sweet spot to slightly below (7-8hz cartridge resonance). You can run some numbers on vinyl engine.

Along the left you’ll see cartridge compliance. AT rates the ART9 at 18×10-6cm/dyne (100Hz). Assume 18×10-6cm/dyne (10Hz).

I’d be shocked if you weren’t pleased with the setup. You get into that orange area and you’d start seeing issues.

I had some concerns initially and even considered some nylon or aluminum hardware I found online somewhere which might’ve save .5 grams on cartridge weight.  But I never saw any gremlins pop up so I didn’t bother. You’d be hard pressed to find a cartridge in the sub $1000 category that didn’t have multiple shortfalls compared to the ART9.
