Who Is An Expert On Acutex Cartridges?

Dan, I think you are inferring that you like the LPM320 slightly above the ART9.  There's no shame in that, in my opinion. 

Timeltel, I finally auditioned the B&O MMC20CL in its B&O Saturn V-like adapter.  The assembly is so light I could hardly counterbalance it.  I set VTF at about 1.2g, based on the age of the cartridge, even though it was sitting in a box all of its life in my ownership. Wow! I was floored, in a good way. Bass was a little shy, which I expect is partly due to lack of use, but the mids are wonderful and the treble is perhaps more extended than any cartridge I've heard on my Beveridge system. (Modified Lenco TT bearing a Dynavector DV505 tonearm into a slightly modified Manley Steelhead driving Beveridge amplifiers/speakers.)  Well, one is usually euphoric after the first audition of a good cartridge.  We'll see how it shakes out over time.  Anyway, I don't miss the MMC1 right now.  Compare to Acutex?  Not yet.

Lewm,

I see you also use a Dynavector arm, in my case a 501 that I've had to rebuild the arm lift assembly on, and rewire. I love this tonearm, though I wonder how much difference there is from the newer models.

Any comment? Very curious regarding information about the Dyna arms.

Regards,,

I own a DV 501 tonearm also, but I have never used it. Years ago it was given to me by a close friend who has since passed away, and I believe he never used it either. So in effect  mine is brand new. Those who have used both the DV 505 and the 501 have written that they prefer the sound of the 501, at least some of them. I have not been able to test this proposition, because I use the 505 on my Lenco . For the Lenco I built a slate plinth which has no provision for mounting a tonearm except by bolting it to the top surface of the slab. So I am limited to surface mounted tonearms like the 505. None of the other Dynavector tonearms will work.

Yesterday I received the one Timeltel referenced that was listed on the 'bay. Running in now on the Viv Labs arm w/Nelson Hold, and sounding very precise. The cart body says LPM and the stylus (sharp-nosed) container says STR, so there's a later version, snub nosed that's not LPM? Also has anyone removed the stylus guard, as I usually do? Looks difficult.

LPM were the later ones with the long narrow snout-like appearance.  There was an earlier or overlapping series simply referred to as "M".  So there was an M320, an M315, etc.  They look more conventional and can mount directly into a headshell without any adapter.  I have an M320 but have never listened to it.  One wonders what I am waiting for. 

Also, now I realize what your question was really about, the full name of the cartridge is "LPM320STRIII".  Timeltel will know, but I am fairly sure the STR refers to the stylus shape, which is elsewhere called "VITAL" in their literature.
