Musical fidelity M6SI problem.

Thanks for letting me know about your situation. At least I have an idea about what's going on now. 

Hallelujah! I just received an email my item has shipped.

I received my M6si. I hooked it up and am breaking it in.

I'm still breaking it in, but so far, no problems at all and it sounds good. I will update in a couple of weeks when it is fully broken in.

I have had the amp for over a month, and I really like it. No problems and excellent for the price. I swapped my Cardas Neutral Reference line stage interconnect to my Oppo 205 with a Golden Presence, and after breaking the cable in sounds great. I replaced my Neutral Reference phono cable for a Clear Cygnus and that also sounds great after break in. I don't have that many hours on the phono stage yet, so now I'm using it more to complete break in. I wasn't  completely happy with the sound until I replaced those two sets of cables. Made a world of difference. The sound stage opened up, and much more transparent. It's a keeper.
