Cartridge ISOLATION; What Say You?

I hve tried the Isolator on Hadcock, Mørch, Scheu and Dynavector arms using various Zyx MC cartridges. In each case it provided a more than subtle improvement.
Millercarbon is right to point out the deleterious vibration transmission from the cartridge body into the arm. Len Gregory would probably point out that the polymer used is too stiff to result in mushy tracking against Atmasphere’s point.

Convincing points Yea or Nay,

My arm/arm-board/plinth (70mm 7 layer JVC) are solid, thus I believe all groove/stylus vibration is going into the cartridge; Plinth factory leveling feet on 2" square isolation pads to lessen my springy wood floor vibrations as I walk away.

I've got a few sheets of 'gasket paper', you cut your own exhaust manifold or carburetor gaskets from it. I'll dig it out, think about it, perhaps try it on one of my 3 arms.

I have a few Decca cartridges. Been using them since the 80s. When I upgraded two of them from the red bendy plastic fitting to the milled aluminum Decapod, I noticed a specific change to the presentation of music. The improved and more rigid mount tightened the music, if you will, lending more stability to the image, faster transients, reduced sibilance, slightly larger and blacker soundstage. While I prefer the accuracy, and would never go back, I will say that it did reduce the musicality of the device. Just a little but it did raise the question of why. Why did it sound more musical? Colorations from vibrations? Harmonics?

My take is simple.  The cartridge needs a solid sink to take excess vibrations that are generated in the cartridge while playing the record.

I tried a couple of isolation devices, and found they smeared the frequency balance and the soundstage, messed with the bass, and generally degraded the sound.

The suspense is killing me. Does Peter Ledermann advocate using the enabler? Or what does he advocate after having demonstrated vibration in the cartridge and tonearm? I agree with Ralph. But then I will be chastised for using logic rather than experience. On the other hand I have had 45 years of experience playing LPs. Anyway I wonder what is the possible advantage of absolutely preventing vibration from moving from the cartridge into the tonearm? Especially if the tonearm is properly damped. I suppose it could not hurt to dissipate that energy within the context of the enabler, so in that sense the enabler may be harmless. For undamped tonearms by extension I suppose the enabler might be helpful. In previous discussions of these devices I mentioned that this issue is much bigger for low compliance i.e. moving coil cartridges than it is for high compliance cartridges which can dissipate more energy in their suspensions.
