Best Platter Material


With different turntable platters being used out there, is there one that is better over amother for vinyl playback?

The most common materials I've come across include:
- aluminum
- acrylic
- glass
- delrin
- ceramic
- copper

Also, if using some sort of platter mat (felt, rubber, cork, etc.) does it even matter which material is being used for the platter?

I've read that Clearaudio is switching from acrylic to POM (delrin) with a ss substrate.

They have been Delrin now for quite some time with their upper tier tables (Innovation series), along with the Concept and Ovation models.
Stanwal is absolutely right. I would never have thought, for instance, that a solid state phono preamp could satisfy me. Tube are better than SS. That's until I heard an ASR Basis. Now tubes be damned (sort of). It's all execution. And also execution. And he's especially right about the third thing.
Lead makes a good platter. Walker and Maplenoll utilizes the mass and non resonant qualities to great success.
