Cartridge ISOLATION; What Say You?

So many interesting points.

Question, is it not the job of the cantilever to function as suspension along with transferring the vibrations to the motor of the cartridge?

In which case, shouldnt it be the only thing that is vibrating/moving?

If the cartridge is also suspended, would that not remove the accuracy/immediacy/directness of the transfer of energy - as the place where that energy should go, would be damped. In being damped, seems like the energy transfer would be reduced.

My thinking exactly, sure it will sound different but different in this case won’t be better. What’s the point in buying a great tonearm if the cartridge is only attached loosely, taped to a piece of sponge type material. BillWojo

There are Head Shells available from very reputable Brands with R&D backing their deigns being marketed.
Magnesium Metal milled on the Top Face to receive a damping material is a Head Shell Design that I use.
I am wondering if the Cartridge Separator as a Interface is a lead on from this type of design philosophy.
I am quite familiar with the offerings from Japan and am not aware of a Separator Material being offered by the Brands that I follow.
Is this something that has been missed by them in their R&D, or is this something that they are not able to add any value to their design intent by going down this road ?  

The Separator Devices usually seem to appear on a sales list from fringe Companies offering accessories, and usually at quite High Prices.

I know the exact same material offered by the Cartridge Man was available in Australia for about 70% less ? than the UK price. 

The Houdini Separator entered the Market with a mixed response, and the time spent undertaking Searches and Investigations of the reports are showing that in general it is not always seen to be the ideal interface, and in some cases even though given an approval on initial use, after extended use and trials, it has not been a keeper device for the user.

Possibly a more secure purchase and one that might prove to be a device that commands a long term usage of the device, might be discovered in trying a selection of different Head Shell Materials.
At the least these devices are very saleable once used, and can be discovered as a used sale for a reasonable outlay.
I have sold Head Shells within a few hours of their being advertised without any need to arrange a Sale Price with the buyer.

As said previously a lot of change to the presentation and sound quality is available to be had with a Platter Mat Change.
IME I am still coming to terms with how a 5mm Forex Foam mat that cost approx $12 is my mat of choice for most listening and is against competitors up to $450.
A Forum Member has took the initiative and purchased a Forex Foam Mat and they have recently informed me their Tenuto Mat is resting up on the Album Stack, they are in no rush to reinstate it.

For only a $40 investment, I bought the Enabler for my $5k turntable with a $4k Soundsmith Paua cartridge. It works and work well. I found it to provide more focus and control without losing any soundstage. It also minimized any thumping going through my speakers when tapping on the plinth with volume cranked. I was convinced enough of its Audible benefits, that I bought another one for my wife’s $1600 tt with a Hana MH MC cartridge. Results were also immediately noticeable for the good on that tt too. I also like the bonus of being able to tweak the tonearm azimuth when using the Enabler.

Enabler Quote:

" The material is similar to a good gasket material, flexible and robust."

Who laughed disparagingly at my idea of digging out my sheet of gasket material for a home made try? I can try one or a few layers.

VTA Refinement

If VTA needs refinement in an arm with no adjustment, I would NOT rely on one side tighter: rather very thin sheets of rigid material on one side, like clear rigid plastic page protectors, cut your own rectangular shape, make notches for bolts. Enough layers to solve it: very tedious, dexterity needed. I like more surface area than round washers.

Hint: I stay calmer when I don't have an audience, otherwise I misbehave seeking sympathy rather than dealing with it.

Then, if using an Enabler type, a material with designed vibration dissipation, I would want firm tightness on both sides.
