Image: Herbie's Audio Lab Iso-Cup with 1" Aluminum Balls (shown with Lampblack Ball).

I find the essential sonic signature of a generic 1" solid aluminum ball placed in a Herbie's Audio Lab Iso-cup to fall somewhere midway between a Herbie's Audio Lab Frosted Acrylic Ball and a Herbie's Audio Lab Lampblack Ball. With my particular configuration (under a vibration control platform for an outboard PSU), the impression of the aluminum ball is a bit laid back like the Frosted Acrylic Ball but more assertive, not as aggressive as the Lampblack Ball, and essentially more analytical in nature than the Herbie's Audio Lab Gabon Ebony Ball. It would seem to be a happy medium, to my ear. That said, the Herbie's Audio Lab Iso-Cup with SuperSonic Hardball is still the best sounding option for a power amplifier application, IME.
