Audio Technica AT33PTG/II MC Cartridge, anyone have it or heard it?

The only thing I don't like is that it tracks at 2.0 grams, I am used to:

Shure V15VxMR which tracks at 1g

AT440ml 1.25g

Shure Elliptical 97xe 1.25g

Grado Mono 1.5g

I believe the AT33PTG-II is beating the Shure V15VxMR because of it's greater channel separation, and it's tighter channel balance. It's not frequency, they produce the same range, detail, it's not about preferred bass kick as I expected, the AT is simply more 'open', the same sounds, but some space between. I keep saying, when you tweak balance of a track that is a little off, sometimes just a little bit, it is surprising how much of a difference it can make, this is similar to my ears. 

The last 2 tracks of side 2 of this, all 3 guitarists play together, one of my all time favorites, and a very revealing test are better than I ever heard them with no doubt. They are 2 great tracks to refine anti-skate as well.

The Shure is going upstairs to my office system, to have a listen out with the AT440ml on the Mitsubishi Vertical Turntable LT-5V

Someone said separation and specs are not a way to choose a cartridge, perhaps, but this AT33PTG-II has the best specs of any cartridge I own, and sounds better than anything I have ever owned, or heard at my Audiophile friends systems.

of course various ... is different than ... published specs are:

AT33: SUT 6.3mv; 15-50k; sep 30db; bal .5db, track 2.0g

Shure V15.. 3mv; 10-25k; sep 25db; bal 1.5db, track 1.0g (brush option)

AT440ml: 5.0mv; 5-32k; sep 30db; bal .75db; track 1.25g

Shure 97xe: 4mv; 20-22k; sep 25db; bal 2db; track 1.25g (brush option)

Grado Mono: 4mv; 10-55k; track 1.5g

I always preferred my Shure V15VxMR over my AT440ml, but primarily because of the brush, in TT prior location on springy floor, now both main and office systems are solid, no bruch needed. We shall see tomorrow upstairs.

Just to complete this thread,

I prefered the AT440ml to the Shure upstairs on the Vertical Mitsubishi LT-5V (no dust issue in my office like downstairs) 

I realized, downstairs, cleaning/testing LP's for sale on eBay, I was putting wear on the fixed stylus MC,

So I found a compact tonearm to squeeze on the left side, now 3 arms, Mono left side; MM rear (removable headshell); MC right side, testing LP's on MM now. Keepers via MC.

3rd input of SUT came in handy. I got darn lucky along the way with this project.

I have been using 60db gain for this cartridge and it sounds great. This is the gain setting that KAB usa recommended. However I punched in a formula to figure out the right gain for this cartridge and I came up with 70db. My Hagerman Trumpet MC has a 68dm setting so I gave it a shot. It sounds much better. More bass slam and more fine detail. This is the result of a better signal to noise ratio.

Loading this cart at 60db is too little. Can’t believe it took me so long to figure this out.

Phono gain alone is never the whole story. You need to add linestage gain. You need to consider amplifier input sensitivity (how many signal volts are required for full amplifier output) and speakers sensitivity . Also room size and reflectivity of furniture. Thus no on line calculator of phono gain can be fully relied upon. But your direct experience counts of course.

Huh?

where do you get these high gain numbers?

I found a chart of Step Up Transformers:

Ortofon, Fidelity Research; Denon; Audio-Technica; EAR; Supex; Bryston; Nakamichi; Sony.

highest gain +36db (XF 63.1) (for a coil with 3 ohm impedance)

lowest gain +16.5db (XF 6.7) (for coils with 40-250 ohm impedance)

..................................................

AT33PTG/II cartridge: .3mv signal; 10 ohm coil impedance

10x formula guidance is 100 ohms impedance to be shown to typical phono stage 47k

(impedance shown formula is: (typical phono stage) 47k divided by XF squared).

Or whatever impedance your particular phono stage is divided by XF squared

My SUT, Fidelity Research FRT-4 has Pass for MM and 4 options for MC.

4 XF (x factors) with resultant impedance shown to the phono stage

3 ohm input: +31db; XF 35.84 = 10.8mv signal = 37 ohms shown

10 ohm input: +26db; XF 20.68 = 6.3mv signal = 110 ohms shown

30 ohm input: +25db; XF 18.27 = 5.4mv signal = 141 ohms shown

100 ohms input: +20db; XF 10.55 = 3.3mv signal = 423 ohms shown

................................

EAR MC4 has 4 options: +30db; +28db; +25db; +20db.

Denon AU-320 2 options: +31db; +20db

What am I missing??
