It might also sound much worse for a number of reasons that would prevent the proper cutting of the laquer master. I have my studio next door to a vinyl mastering studio and it is truly a fascinating craft. The cutter might have to narrow the stereo image to prevent the needle from jumping out of the groove. Often this is done by mono'ing the low end. The tool he uses will gradually mono the low end on a slope from i.e 150hz and down. This can lead to less low end especially if there are phasing issues that will cancel out signal when collapsing to mono. They will also high pass from 20-30hz and low pass (can't remember how low he went), and sometimes even de-ess the entire mix!

Also if the sides of the vinyl are too long, the sound quality will suffer badly.

And if they screw up the cut, it's a lot of $$$ for each laquer master and the diamond needle for cutting doesn't last many records either.
