I have used a 2" slab of Starboard, which is an acrylic type of board. I can't say it was an improvement though. the Cosmos IV is pretty good the way it is.
Isolation Platform for my Sota Cosmos?
Delving into the murky waters of all things Isolation Platforms to complement my Sota Cosmos turntable to try to understand which - if any - isolation platform would work best with my Sota Cosmos turntable - which is a suspended turntable. The Cosmos already has great isolation qualities so i am wondering if there is actually anything out there that could improve the sound quality from this TT. Any suggestions? Thank You
