I have both products, and could probably do a comparison, but it would take some work to set up. I have the ZaZen and the Townsend air platform. ZaZen is on my turntable and the air platform is on my XBOX One. (but, why for an XBOX? Well...when you play blurays, the disk spins, that causes vibration and vibration reflection. An acoustic platform mitigates that.)
I had been wondering if I shouldn't flip them.
