Isolation devices and CDPs

Also check out Herbie's Audio Lab... a number of interesting, low cost options. One thing I've been trying to good effect is placing his grungebuster dots between my cones and components. Seems to make a nice improvement - particularly under my CDP. YMMV

I think the EAR Acute in particular benefits greatly from 2 things. 1. Tube rolling, I found the Amperex US 7308 very good and the Seimens early CCa excellent when compared to tubes provided. Several others I tried did not beat the stock tubes. 2. Vibration isolation and mass loading.
Overall I feel the Acute really sounds excellent with these 2 tweaks. My only criticism is it could have been built a little better but then the price probably would have been a lot higher.

Rja: What have you tried for vibration isolation?

A Gingko Cloud and VPI brick over the transport. I was thinking about a total resonance control package from GNSC but it would have voided the warranty.

Owning four Vibraplanes, I can testify that when properly set up, these babies really do the job. Have had these under my amps and sources for a decade and they work wonders. Use brass footers or cones between 'plane and equipment, although Golden Sound's feet supposedly are wonderful, too. The footer interface is up to you based on sonic preference. But as a platform, the Vibraplane is great for sucking up those unwanted vibrations from multiple sources. Remember: the 'plane eliminates both horizontal and vertical vibrational energy.
