Musical fidelity M6SI problem.


Has anyone had crackling sound problems with their M6SI integrated amp?

Different model, but I have really enjoyed my Musical Fidelity Tri-Vista over the years. And small tweaks have made it that much more satisfying (upgrading power cord and umbilical cord(s). It has dispatched some pretty good separate preamp/amp combos over time. Good to hear that the M6si is also satisfying. I'm not really in the market right now, but I would like to hear a pair of their current M8 700 watt monos.

Hi, I've owned M6si for over 5 years. I've had crackling sounds and took my unit back to my dealer to get it diagnosed. Problems with both power unit and capacitors. Quoted me about 33% of the cost of a brand new unit to get the problem fixed/replaced. Pissed like mad. These problems shouldn't be having for relatively new units like mine, it's kept in a well ventilated place and not used daily. I don't drive it hard too. Service guy tells me it's a common problem with this model.

Crackling sounds are usually a dirty potentiometer. Some tuner spray fixes that. It is rare for caps to go bad in just a few years and I'm not sure what a "power unit" is. Very curious. 

Yes from what i read the M6si has this issue with crackiing sound coming from the speakers, which is power supply related. Does the M5si have the same issue?

 

Thanks.
