I didn’t, using it upon the reviews for a slew of kit, one of which was the Kenwood FLAC headunit seen here: here and if you ain’t clicked away here’s a quote: ‘I fired it up, playing it through a rather lovely Soundstream Ref 4.400 amplifier of reference quality like it says – into some high quality speakers with tiny bullet tweeters and sweet midband capability as well as a bit of bass and I was just delighted.’ Rated at four by seventy watts, this amp will happily run at two ohms all day.

So much so, that you will find it used as a reference amp (As in no need to listen to anything but the speakers you are testing, like it was, ‘A straight wire with gain’) in a goodly few Talk Audio reviews done recently, prior to this date. I found it clean, sweet, just powerful enough and as long as not over driven, possessed of great clarity and headroom. The GENUINE 102dB signal to noise ratio means huge fidelity and the enormous damping factor really keeps the amplifier’s grip tight on the tunes. In A NutshellĪ pretty and retro-looking amplifier that has some serious electronic constructional chops as a high sound quality product. Below the specifications, I publish their bragging rights about how they design their amplifiers, from their USA website. This is a four channel amp of the Soundstream Reference series, yet the makers state that certain components have improved down the years since they were in production a decade ago and that they are even better nowadays.

The intention was for the return of an amplifier legendary in its own lunchtime.
