Musical fidelity M6SI problem.

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.

My unit is almost a year old now, and I have no problem with it. Hopefully, the newer ones don't develop this problem. With the large quantity of these units sold, there are only a couple of people who have posted a problem on this forum. I wonder if they have a good power source and surge protection?

Well, now I've owned mt M6si Integrated for almost 2 years and use it a lot. I have not had any problems and it sounds great. 

Almost Four years now and no problems, just enjoying the music.
