The Motif series of gear was Conrad Johnson's "Rolls Royce" solid state product introduced in the late 1980's and is known for their liquid midrange reproduction and tube-like signature. This is a fantastic sounding, audiophile quality amplifier with superb quality construction.using MOSFET input and output stages.It was Conrad Johnsons attempt to enter the market place of Threshold, Krell, Jeff Rowland and Mark Levinson.Cosmetically it is very nice clean nice condition.

The face plate is quarter inch thick and is rack mountable. The case itself is high quality brushed aluminum. On the back are very high quality teflon insulated RCA inputs and 5 way binding posts.Quite rare and hard to come by. I am its second owner. The amp has played with no issues and sounds gorgeous with beautiful extended and grain free high frequencies, neutral midrange and powerful tight bass. Absolutely incredible in hard to drive speakers such as the ribbon Apogees or Magnepans. Stereophile’s Tom Norton rated it as one of his favorite amplifiers of all time.The MS100 is rated at 100w into 8ohms; 200w into 4ohms. Dimensions are: 19"w x 7 1/2"h x 18"d - 60 lbs +/-
