Conrad Johnson's Rolls Royce build, this total overbuilt 50 watt solid state amp is the best sounding solid state amp I have ever heard. No harshness or high end glare- very musical. There rarely come up for sale. This one is in excellent condition visually and functionally. 50 watts into 8 ohms, 100 into 4 ohms. Price is $825, add 3% is using paypal, no overseas shipping. Buyer to pay actual insured fedex ground shipping charges. I will pack it very well so it arrives safely to you. Email is apt_one@yahoo.com - this is a great amp and blows away the CJ mosfet MV solid state amps- there is a much better quality components. Heard it against them and this amp is clearly superior. Power: 50 watts per channel RMS both channels driven into 8 ohms
from 20Hz to 20KHz at no more than 1% total harmonic distortion or
intermodulation distortion.
Sensitivity: 1.1V to rated power.
Phase: Phase correct (non-inverting)
Frequency response: 20Hz to 20KHz +0, -.25dB
Hum and noise: 90dB below full power output.
Input impedance: 100K ohms.
Dimensions: 16.75D x 19W x 5.25H inches.
Weight: 40 lbs. Motif is the result of conrad-johnson design’s
research into the application of solid- state devices to the reproduction
of recorded music. The design and materials have been carefully selected
to yield years of unvarying excellence. STEREO AMPLIFIER MOTIF was Conrad Johnsons best effort to enter the market place of Threshold, Krell, Jeff Rowland and Mark Levinson. There were three models in the MOTIF line. The MS50 | MS100 | MS200. The MOTIF MS50 retailed for $2,350 when new. In today's dollars that is $4,950. The MOTIF MS50 is conservatively rated at 50 watts per channel. An amplifier that retails in today's dollars of $4950 speaks to the build level and price-point of this amplifier. While some may scoff at the 50 watts, I have driven large speakers such as the Eminent Technology LFT-8'S with success. The build quality is exceptional. I have always thought that the MOTIF MS50 was a superb sounding amplifier that brought life and musicality to my recordings. 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. The MOTIF MS50 is quite rare and hard to come by. The amp has played with no issues and sounds gorgeous with beautiful extended and grain free high frequencies, neutral midrange and powerful tight bass. Some people have used these amplifiers to power hard to drive speakers such as Magnepans or Thiels. Stereophile’s Tom Norton rated it as one of his favorite amplifiers of all time. Conrad Johnson designed the amplifier with top of the line power supplies and capacitors and output devices. As you can see from the photographs, the amplifier is hand made and uses nothing but the best quality internal components. DESCRIPTION The face plate is done in argento, slightly brushed with royal blue silk screen lettering 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.
