the cables attached to the turntable, like jackfish described. maybe there is a version A/B or something. anyway it sounds great, it kinda blows away the rega RP1 that i traded in to get this piece. this has a richer sound with more clear and defined bass. this paired with the musical fidelity V-LPS2 phono stage (instead of the NAD PP2i phono stage which i also traded in towards the turntable) is a definite improvement in sound. i think i could live with this for awhile. thanks to jackfish and commsysman for recommending these components.
