The early PL systems are sometimes populated with really shitty mother/daughter boards and are near impossible to work on. The Star Trek joystick pre's are the biggest pieces of junk ever built. Nothing wrong with having a full PL system but there are better options when wanting to "Up the Ante". When you go out and spend thousands of dollars on a KILLER turntable and then back it up with sub-par pre's/amps, it's counter intuitive.
