SYMPOSIUM works better than anything else in my system.I have Rollerblock HDSE with #2.5 balls under my amp and Battery power supply for my TW ACUSTIC AC1 turntable.Using Rollerblock Series 2 under both my AUDIENCE line conditioners 6TS they improve bass ,highs, air, bass speed and staging its imazing.Also using ULTRA STEALTH amp stands under my amp and AUDIENCE units and svelte under preamp,tuntable power supply and preamp power supply.Everthing has improved my sound.Oh yes using SYMPOSIUM ULTRA STEALTH under my TW ACUSTIC AC1 turntable.
