Herbie's Audio Lab Iso-Cups w/balls (or a lower-cost set of domes)...

I'll recommend a set of Herbie's Audio Lab Iso-Cups w/balls. I'm very pleased with the Iso-Cups and the previous Gabon Ebony Balls and SuperSonic Hardballs when placed under my preamplifier's power supply and under my power amplifier. However... Herbie's Audio Lab seems to have replaced the previous Gabon Ebony Ball (and SuperSonic Hardball) and Gabon Ebony Dome with an acrylic material. The web site mentions, "...our newest domes deliver tonal qualities and timbre uncannily similar and virtually identical to ebony domes (based on A/B blind testing and critical auditions). Slightly better focus and three-dimensionality is sometimes perceived with acrylic domes, however. With more-perfect material control and dimensional stability, Frosted Acrylic Domes seem to achieve a slight overall superiority...".

Herbie's Audio Lab Iso-Cup with Frosted Acrylic Ball: $29.95 ea. (I use a set of four Iso-Cups, but a set of three can be used):

A lower cost option is the Frosted Acrylic Dome with 1.6mm grungebuster base: $4.49 ea. (a set of three or four can be used):
