1ohm stable,transparent sound, small package without endcaps,

emphasized treble, runs hot, power hungry

another quality product from Sony ES, just good old honest transparent clean power. I would rate this amp as an audiophile sq product. I have used many amps from ppi,fosgate,carver,tubedriver,zed audio,harmon kardon, coustic design reference,nakamichi,soundstream,tru,audison,xtant ect. I would rate this amp in the slightl upper middle half.
