Who Is An Expert On Acutex Cartridges?

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.

I have no specs on the effective mass of the RS Labs arm. but the arm tube seems less massive than the SME3012R, for instance, at 12g (plus headshell, of course).

As for the emphasis on plectrum strokes, it's just something I notice more on MMs or MIs than on MCs. More a matter of preference than too much or too little.

Timeltel, thanks for the tips about tracking weight and break-in! Will look for changes in staging. Unfortunately (??) I've got a DaVa cart on another arm on the same table that I'm focused on right now.

Lew, I also have a 20CL that I like a lot, tho wouldn't say it's a bass monster. It is a low rider, tho, and I reduce the tracking force when using it, tho it still tracks great.

Installed the 20CL. It's ever so slightly higher in back, but still delivering prodigious bass, VTF is at 1.0. Did the low riding heal itself over time?

No, I was referring to my own sample, which I remember having a somewhat collapsed suspension but which seems fine now. Suspension hardening in the right direction??

As for the Acutex, after 20 or so hours, timbre is richer, tho I haven't noticed a fuller soundstage yet. Maybe I should try it on the heavy Sperling arm, a soundstage champ. If the new Kuzma Sapphire at 60g effective mass is supposed to work w/most MCs, the Sperling at maybe 30g might be OK w/a high compliance MM. Anybody know the compliance of the 320?

After reading some of the Lenco Heaven thread, I was thinking about the lightest tonearm I have. So I installed the LPM320 in the RS Labs arm on JVC TT-81 in custom plinth with VTF at 1.6g. Now that it's burned in, it presents a wide soundstage and engaging level of nuance and detail. I have noticed some emphasis on string/plectrum contact, that seems to be a signature of MMs/MIs vs. MCs. Maybe I just have a MC bias that it doesn't belong there.
