I also am using the Wireworld Electra 7 PC and it did respond well to it with nice smooth bass. My system is dead quiet too.
I just ordered the Benchmark ABH2 to have a shootout between the two.
best-sounding class D amp?
I'm not interested in starting another discussion about technology, or performance parameters. (You know who you are.)
I know that there are different brands and designs of modules used in these amps, and different implementations, with additional maker-specific circuitry around the module.
What I *am* interested in hearing about is first-hand listening impressions of the most natural, full-bodied class D amp you've heard, with a preference for those (few?) that hew to the slightly warmer rather than cooler side of neutral.
