AMS50 

ANTONY MICHAELSON SIGNATURE  

50W Pure Class A Dual Mono Power Amplifier  

 

 

Thank you for purchasing the Musical Fidelity AMS50. 

The AMS50 uses the latest in low distortion circuitry in a bridged configuration which delivers 50 watts of pure class A power. 
The AMS50 is designed with pure undistorted experience in mind. Overall the listening experience is greatly improved because of 

dramatically lower distortion and increased dynamic range. 

The AMS50 accepts both XLR balanced and RCA line level inputs. When driven from a balanced pre-amplifier the sound 

quality is greatly improved because the balanced cable cancels out noise and interference artefacts, giving up to 12dB increase in 

dynamic range. 

The Primo Pre-amplifier is an ideal partner as it features a fully valve signal path and true balanced operation throughout 

Alternatively, the AMS50 can be used as a conventional power amplifier driven by a high quality preamp. 

The AMS50 is a perfect answer to pure musicality in a single beautifully engineered package. Used properly and carefully, it 

should give many years of outstanding musical reproduction. 

Dust regularly with a soft duster or soft brush, but be careful when using cleaning or polishing agents - they may harm the surface 

finish. 

If there are further questions about any Musical Fidelity component, please consult the dealer from whom it was purchased, who is 

there to help and give advice.
