Did you pick up the Super Mario Bro's 2 OST from 2D Ninja?
Have you bought any of Trademarkoflove's square lathe cut 7"s? I bought Majora's Mask and boy oh boy is it bad, the first side is damn near un-listenable, it's so noisy, the first track which is pretty quiet you can barely hear the music. Side B fairs better but still doesn't sound great, I have to turn up the volume almost twice as much as any other record in my collection to hear it. I asked a few others and they said their copies were not great sounding either.
