Sony debuted a new portable speaker set for the NW-A3000 + NW-A1000 featuring the S-Master Digital Amplifier. Model number, specs and so forth are not available at this time and the demo unit was not very functional. From what I could tell, it will have a “surround” type option for sound, line in, and infrared remote capabilities. It did however sound extremely good for a portable speaker set; bass was actually present instead of transparent and reasonably tight which is very uncommon amongst such setups. It will be a hot seller, and should debut in March, 2006 — pictures after the jump.
