One relatively inexpensive means to lowering surface noise is cartridge alignment. Many (or most) users of the MintLP arc tractor find that once alignment and overhang are optimized, surface noise becomes less prominent. Stringreen pointed this out after getting his arc tractor. I can't recommend it highly enough. Even at the new price, $110, it is a screaming good deal. You owe it to yourself to find out what your analog front end can really do. You will be amazed, I'll wager.
