Just inherited this system from my Father, who passed in June '02. He was the one responsible for my love of music. Right now I'm looking to upgrade the phono cartridge (I know direct drive isn't ideal) I'm not new to the scene, but I could use some suggestions.
Grado cartridge, dump the equalizer out of the sytem, make sure you have some upgraded interconnects/speaker cables as this vintage probably has less than optimal. Purchase the smaller Isobearing supports for the CD player which will clean up the attack, change the imaging and support bass. Clean up all the inputs with Caig or something similar. That's it. Great little system.
