Cartridge ISOLATION; What Say You?

Just ordered a Houdini
I’ve always been a believer in trying out for yourself.
All this discourse means nothing.

FWIW, I've used a small amount of blue tac between my cartridge & arm for a few years now & enjoy the added clarity that provides. Still clamp the cartridge down with the screws so it is absolutely solid.  

I was wondering about the Houdini @slaw , let us know how that works. I just gut thru putting the funk firm mat on one of my tables. It’s is so good I bought another for my vpi. If the housing is as good at the mat. I’m in. 

Houdini I mean. 

I'm sure Lewm and Atmasphere shed some light on this.

Cartridge isolation is very important but at what level? This is not difficult at all. The cartridge has to maintain a fixed orientation to the record. ANYTHING that corrupts that relationship like unipivot arms is bad. So the solution is, you isolate the entire turntable or rather the chassis that carries the tonearm and platter. This is the rational behind suspended turntables. They keep the environment from interfering with the cartridge without further corrupting the relationship of the cartridge to the record.
This cartridge isolation pad is beyond silly. What it does is dependent on the surface area of contact as well as the tightness of the screws, two variables that can not be easily controlled not to mention it corrupts that relationship.
