Lower mid compliance carts with Phantom tonearm

Tz...that's an interesting one. TBH I don't remember actually using the HFN/RR Test Disc to check H&V resonance in Real Time but have had no issues whatsoever with any disc and I'm about halfway through the life of the cart. My last cartridge, which was used on a 13g Linn Ittok LVII, wasn't so blessed and unfortunately turned out to be sensitive to "pinchwarps"....

The Phantom's bearing does have a damping trough which allows some tuning but the Phantom is reasonably well damped even if you didn't use it.
After initially installing I subjected the Lyra (Delos) to my "nightmare-disc-from-hell" and it sailed through it with flying colours - as if tracking by lasers. After that I ceased worrying :)

I would describe the general behaviour of arm/cart as imperturbable or rock solid.
All the best,

BTW....The other cart wasn't a Lyra but an MMIII...and the Ittok was 11+g - apologies for the typo. (At least I managed an odd no >10g ;)

The compliance calculation gives you a number, but it will be pretty useless. The material of the Armtube (steel, aluminum, wood, ceramic, carbon...) is a factor, the quality of the bearing the next, proper geometry (when it is wrong it is also useless) and then there are some more...
I used a lot of cartridges (maybe 20 or so, I forgot) with the Phantom Arm and that is one of the very rare ones which work very well with almost all. Maybe there are some exceptions but I didn't find one of them.
I had combinations with 9.5-10.3 from that compliance calculation and I got better performance results with those carts in different arms.

thanks for the responses
