Anybody out there using a Class D digital amp? Like the Bel-Canto amps? Just wondering what people think about these. They are usually less expensive than Class A/B amps, light weight by comparison, use less electricity, run totally cool, and are still very powerful. Sounds like a dream right? Yet there seem to be many angry critics of this technology. Thoughts? Thanks.
