SMS Classic - Check

JBL K120 in SSP cab - Check
MC 250 - Check...and Fail!
I've been putting my Jerry rig together for years and finally picked up an SMS in the fall and also snagged an MC250 off of ebay. When I bought the mac I did not yet have the SMS so instead of trying the mac first, I brought it straight to the amp tech for a recap/service/optimize/1/4" inputs...
The tech had it for 2 months and was extremely thorough in his work, itemizing every part and detailing every single thing that he did (with before and after pictures). Also he noted that it was testing well over 70 watts of ouput on each channel. So I finally picked it up last night swapped out the Mosvavle MV-962 for the MC250 and started playing...
Immediately I noticed that the tone was colored and not in a good way. It seemed that it was adding in a "dark color". I don't want to go as far as muddy, but almost like you had the tone knob tweaked with bass.
My problem is that I don't have anything to compare this to, as I've never played through an MC250 before, but I know this can't be right. Does anyone have the SMS> Mosvalve/MC250 combination and notice a much darker sound when swapping out the Mosvalve for the mac? When playing through the MV-962 there's no darkening/colorization of the tone. It comes out clean/clear/pronounced. The mac is thick with this darkening tonal quality to it that is swapping clarity for muddle.
So my question is, does anyone have any inkling as to what the issue could be here? I have no idea what to tell him to fix to make it "right". If I could just try one to have something to compare to I would probably be in a better situation as far as articulating the issue.
Any help/comments would be greately appreciated. I'm at the end of the road with this and don't know what else I can do to make this work.
Thanks!
