D-Sonic M3-5400-7D-Sonic is a company that I had been tangentially aware of for many years due to their direct marketing efforts on websites like Audiogon.

Bryston 28BSST2 Monoblock Power Amplifier

Bryston 28BSST2 Stereo AmplifierLately I had been sampling the Bryston Mini T Bookshelf speakers with my reference amp, a modest Marantz Integrated, and though they matched well I wondered how they would fare with some serious Bryston power behind them.
