Who Is An Expert On Acutex Cartridges?

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.

For what it's worth, I realized the other evening that the MMC20CL was adjusted so that the tail was "up" just a bit.  It's sometimes difficult to level the very short vertical arm wand of the DV505.  Anyway, I did lower the vertical pivot just a tiny bit so that the wand at least looks more exactly level to the surface of the LP, and bass did improve.  I am tracking at 1.2g.  What do others recommend for VTF?  One internet source recommends 1.0g VTF, but that was the spec for a brand new cartridge in 1987.  I figured my suspension must have stiffened over time, so chose 1.2g to start out.

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?

Max, if you are asking me about low riding, mine never was and is not a low rider.  What I said was that I had inadvertently adjusted VTA such that it was "higher in back" or tipped up with respect to the pivot.  Leveling it did improve the bass impact.  I will try going down to 1.0 g from 1.2g VTF to see if that is better.

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?
