Musical fidelity M6SI problem.

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.

verndantaudio, 
                        I really like the M6si after break in and matching cables for it. Do you think it's worth it to upgrade the phono stage To the M6 or M6x phono stage?

Well, everything is broken in now and I'm really happy with this amp. Even the phono stage is good, and not one problem. 

I missed this note.  Glad to hear you are happy.  It is a heck of a good amp.  I do think the M6 phono stage is a big step up but if you are happy with what you have...awesome!

Yes it is, and thanks for getting back to me. Based on your reply I am interested in getting a better phono stage, but I'm not sure which yet. The M6 is one option.
