I would not at any time deny myself the experiences and learning that can be had from the introduction of different materials as a Platter Mat.
The Platter Mat is only a interface, a separator of a Platter from a Material that has a data etched into it.
There is a lot that can be discovered, as to how a particular material used for Platter Mat, offers a change to the perception of a replay when used in different environments.
Additionally, there is the learning of how a particular material used as a Platter Mat, can contribute to increasing/decreasing smearing, which when present and detrimental in its effect will mask the micro details. Quite possibly not enabling a very well engineered Cart' to stand out too much for its qualities in comparison to a lesser Cart'.
Creating different interfaces by using differing Types of Materials for a Platter Mat does not come with a considerable expense and a exceptional material can be found for not too much monies.
A friend with a Belt Drive TT, stuck loyal to a Manufacturers Mat for numerous years. I brought to them a selection of mats in different materials and the one they chose over their long time used one was a 5mm thick foam.
The foam mat was bought as part of Group Buy at approx' £8, it is the same material that is used for a Branded Mat that sold for over £100 as a 3mm foam.
In my system the 3mm foam was rejected, the 5mm was much more successful, this proved the same for the Belt Drive TT.
I have a large selection of Platter Mats to be used for demonstration and loan purposes.
Four of the Platter Mats I have, are selected for regular use and are each having a unique and desirable influence on the SQ. Three of the Four Selected Platter Mat Types are Branded Models and have a combined retail of approx' £700+.
It is not too difficult to understand that a £8 mat is the other in this selection of Platter Mats.
Another forum member picked up in a commentary I had offered in the past on the 5mm Foam Mat, and inquired how to acquire one. They informed me at a later date, the mat has now become their main used mat, superseding a £300-400 Gunmetal Mat.
