Cartridge ISOLATION; What Say You?

Putting a Isolator between the Cartridge and Head Shell serves one purpose IMV, it can change the perception of the presentation for the listener who is quite familiar with a Systems SQ.
The user of the Isolator is in their assessment liking the perception of the sound now being delivered or they are not.

It is possible for myself to change a perception of the sound in my system in a much easier method and that is to exchange Platter Mats.

The Science is the same as it is quite basic, the new material at the interface, either stimulates an individual and it becomes likeable or it does not.

Platter Mats are much easier to swap out than Head Shell Isolators.
The two methods probably share a requirement where the VTA might still need to be adjusted to get the full impact of the changes being made.   

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.

These days, he's not widely recognized. Surely not a "fringe company"

Making a Claim about the Proprietor of the Company or their History in the HiFi Industry is something I did not refer to.
I am very up to date on the Companies Products and the History of the Proprietor.

I did make a statement about the Companies Position in the Market
Fringe Company - Not Part of the Mainstream - Peripheral - At the Extreme, I think I am reasonably accurate with this assessment.

I have no objection to how or where a person spends their hard earned cash, my storage boxes are full of unused items from such spending.

In saying that though, Long-Term buried and very difficult to find Rothwell Attenuators, once found, proved to be a very valuable reintroduction recently, especially the -15db.
