Tonearm resonance

I don’t see a compliance mismatch so unless something is wrong with the arm bearings or with the cartridge, there shouldn’t be an issue. How do you know there’s resonance? If you hold the arm pillar with one hand, and the headshell with the other, do you detect play or is there no movement?

If you are experiencing "resonance", consider a better turntable before upgrading cartridge.

You could try wrapping the arm with 10 turns of PTFE tape halfway up and at the bearing end as an experiment. You could also try increasing the mass of the arm by adding another nut to the bolts or using brass instead of aluminum etc.

No risk except shipping cost to try Funk's Houdini

"Funk says “Decouple”, that's why Houdini was developed! This patented little device blocks those damaging arm vibrations and Immediately your sound improves…a lot! It’s as simple as that."

"Just try it and hear, especially on your modest deck. (You’ll get your money back if you disagree…only, you won’t!)"

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

I recall a thread about a thin layer of soft damping material between the head-shell and cartridge that solves/prevents vibration/resonance, some highly recommend it.

I seem to remember it costs a lot less than the funk one you mentioned.

anyone know what is is _______ ?

The OP is asking specifically about that and mentions it by name!

Funk Firm

There’s another by Origin Live called the Enabler IIRC.

anyone know what is is?

noromance, good solution

Origin Cartridge Enabler

they mention other solutions

"

Cartridge isolation works

The idea of decoupling the cartridge from the tonearm is not entirely new. The Cartridge Man isolator does this successfully for many arms.

Another alternative promoted by Dynavector importer Pear Audio suggested 3 plastic washers placed between a cartridge body and headshell - this also worked effectively."

Cartridge Man

the text/his test results are worth reading if considering this

back to Origin:

The key advantages of the Cartridge floater are:

It sounds brilliant

It’s easy to fit

Low cost at £19 (performance improvement can be valued at over 10 times this figure)

It works with all cartridges (from £35 budget up to £8000 high end cartridges)Provides the ability to slightly adjust azimuth on tonearms which have no such adjustment."
