Check you connections first. Could have something connected wrong?

Check tonearm wiring, particularly the ground wire, including the cartridge/headshell connections.
also - is your table/tonearm new? it's possble the internal tonearm wiring is the culprit (especially if it's used). You may want to check each of the leads for continuity and shorts from the headshell to the interconnect. Also check your ground wire for continuity from arm to preamp connection.
thanks for the input guys.the vpi tonearm is used but is the same one that i demoed at the store with the tt,which is a tnt junior.the only thing different about the unit is the phono cable.i have a multimeter,how would i go about checking the integrity of the cable? i just tried unhooking the phono cable from the pre but get noticeable distortion from my left speaker only when i play a cd.cheers.
i have had some improvement,seem to get a better connection with my cardas ic so i switched those in and moved the looser fitting ic's to the cdp.did have to turn the volume up considerably when playing lp's.still way too much distortion in the left speaker to be considered as normal.music really seems to be in the background.
to mr dicobrazil, if you want to check the integrity of your phono cable get your tester in continuity, disconect the four leas from the cartridgg, now take the other end of the cabla riht ch rca red the center of it should show continuitty with the red at the cart.end and the ground with the green, at the left channel rca the cente goes to white and ground continuity with the blue, remember to clean the conectors what you get out of the cartridge are mili or micro volts. hope i help you carioca

I'm not sure I'm following your point about cd distortion, but it sounds like it could be a problem in your selector switch as suggested by Dweller. If moving it back and forth has an effect, you may want to go further and buy some selector switch cleaning solution and give it a good spray. In my limited experience, selector switches are as problematic as are IC's with the kind of symtoms you describe.
As for checking continuity with your multi-meter: Set your multi-meter in "continuity mode" or "buzzer" (depend on your meter but they'll call it comething like that. Then test each lead for continuity and shorts. For continuity, you touch the meter probes to each end of the cable. If it's good, the meter will buzz, (if not, no buzz). For shorts, touch one probe to one + end, one probe to the ground sleeve. If there's a short the meter will buzz, (if not, no buzz).
Of course a quicker and easier way to eliminate the interconnect as the problem is to try another interconnect.
