Wetfeet48,
In your initial post you said you just set up the table and there is no bass. Inna has a point - initially there is not much bass.
It does sound like you have the channels out of phase, even though you checked. This could occur with a mislabeled connector anywhere from the cart itself to the phono stage. To check for this condition reverse the wires on one channel and see if the bass comes in. You can do this at the cart pins by switching the tags on the pins - either red/green or white/blue.
Regards,
