Summary: Efforts at Bel Canto to improve the
third-generation ICEpower module seem to have succeeded. The REF500 monoblocks delivered
on the promise of low noise, as evidenced by good detail retrieval and heft amidst notable
dynamic drive and power. They were subject to burn-in and cabling issues, as most amps
are. I enjoyed my time with them and suggest a personal audition -- just be sure they are
fully burned-in before you reach any decision.
