Problems with a new MF M5si

Hello,

Several months ago I bought a new Musical Fidelity M5si Integrated Amp, and after connecting it up to my system I was disappointed to hear that the audio sounds a bit distorted. I have tried different input connections on the unit, different interconnects and different sources (CD/Blu Ray Player and a Music Streamer).  When running the same sources through two other components (an NAD Integrated and a Marantz AVR) and using the same interconnects, I don't hear any of the distortion that I'm hearing when using the M5si.

I did send the unit to Musical Fidelity and they have told me that they can't find anything wrong with it.  So now I have it back, and with the same distortion issue. 

I am kind of stumped now, and was hoping that there might be some options available such as bringing it into a dealership near me and have them hook it up and check it out, or maybe bringing it over to another forum member's home where they could hook it up and audition it with their system, and see whether or not the distortion is still heard.

If anyone has suggestions or help, please let me know. I am in the Orange County area in Southern Calif.

Thank you,
Greg

It is very frustrating that Musical Fidelity was not able to identify the issue. If the audio from your Musical Fidelity M5si sounds distorted, consider the following troubleshooting steps:

Check Connections: Ensure all cables are securely connected and of good quality. Loose or unsuitable cables can cause distortion.

Speaker Polarity: Verify that the speakers are connected with the correct polarity (+/-) at both ends.

I had a similar issue with a Magnum Dynalab tuner The factory said the unit was perfect. I checked everything and discovered my power cord was causing the issue. I replaced the power cord and everything was fine. Maybe also replace your interconnect cable.

Taking the unit to your retailer is a great suggestion.
