    Static, hissing, scratching .... pegged my Amp meters (Mc7300)...

    Turned it off, and on a few times...same thing......on EVERY channel...

    Re-Updated the Firmware to 1.0.4 (which I had done a week or so ago), and the problem seems to have gone away...

    If this had happened at high volume it probably would have fried my Wilson WATT/Puppys.....

    I've only had this preamp for about 2 weeks, (from AudioClassics) so I can return or exchange it.....

    Should I?

    Absolutely! Contact them first, of course.

    I'll do that, but as of this moment it's completely dead, except for the occasional static burst... :-/

    Call Ryan and get it back to them. They'll make it right.

    Ditto, ditto and ditto. Then tell em to give you a kick ass discount on a C52. :) AC has always been first rate and they should also cover shipping both ways for you as well for something like this. Good luck!

    100% YES, RETURN and exchange, if that is what you wish. This should not happen on a new McIntosh.

    I just sent my c47 in today. It did the same thing. I'm using a mc352 with Martin Logan odysseys. It acted up last week, i shut it off and then worked fine the next day. I was listening today and the s!@t went crazy and I ran to shut it down, plugged in my other preamp and all was fine. I went to FedEx and sent it off. I have nothing but great things to say about audio classics as they said they will make it right. I believe they have made me a repeat customer and my next purchase will be with them. Stuff breaks down, it just sucks cause I had a couple days off

    AudioClassics as predicted did make it right, and covered all the shipping etc.... I upgraded to a C52, and am especially glad of that given the post above.... and yeah, I do miss it, as I had some free time as well for listening... I am excited to receive the c52...
    I have other stereos tho, and had fun with those.

    The above post from Dc83 makes me wonder if this might be a firmware issue with the C47, as I just upgraded mine to 1.0.4 from 1.0.1 ... Dc83 did you recently upgrade your firmware on your C47?

    No sir, I had just upgraded from a c46 to the c47. It was a b1 unit and I had it for maybe a month. I'm not sure if it had the latest firmware or not. I definitely thought similar when I read your post so I replied with my issue.
