Damn, I had to register and ressurrect this old ass thread just to say how wrong you are.
I grew up playing MK1 in the arcades and the music is printed onto my memory, because I just LOVED it. When I tried in MAME a few days ago, I couldn't believe how wrong it was sounding. Only loud boomy drums, very faint synth, not right at all.
This is actually very easy to verify in the newer arcade collections. The sound is enhanced, but balance of instruments and sound effects is very close to the original and wildly different from MAME.
Unfortunately, I don't have access to an arcade machine anymore, but comparing to the current-gen ports, setting both ym2151 channels to 2.00, dac to 0.26 and oki to 0.37 brings it very close and definitely faithful to my memories.
This problem seems to be specific to MK1. At least, I checked MK2 and it doesn't have individual sliders for each sound board channel, so there's no way of messing the levels like this.
