The impressive sound of the Focal Maestro Utopia III speakers in one of the SSI rooms being run by retailer Son-or-Filtronique was familiar from my July 2010 review
but the small amplifier driving them via Crystal speaker cables was not. It was the Micromega AS-400 integrated amplifier ($4995), which Art Dudley will be reviewing in the July 2011 issue Stereophile
. As well as the usual analog inputs, the AS-400 accepts WiFi audio data via a new version of the French company's Airstream module and uses a high-quality D/A section using Cirrus Logic DAC chips.
