Guys, Thank you for the additional suggestion. Let me quickly summerize what has happened so far..
I finally got a reply from Moon Audio about the hum problem and whether it may be related to LP-110 phono pre-amp. The rep suggested that because the U-Turn unit's ground is built into the left channel of the turntable, the Aux/phono input of the Conrad Johnson PV-14SE may be designed to expect a usual ground wire to come from the phono plugs and be attached to the grounding screw of the LP-110. After asking about the other inputs, he suggested plugging the output cables of the Moon box into AUX 2 input, which is not designed for a ground lead wire which the U-Turn has solved by in the left channel input of the table.
I tried it, and it still did not stop or diminish the hum between tracks and the lead out LP grove and also seems now to be somewhat audible playing LP's
Next, I replaced the skimpy supplied phono cables with a pair of Audioquest "Coral" ICs which I had owned for 10 years. The pair cost about $45.00 and is definitely budget. Same thing....hum. I then proceeded to swap the Canare IC originally used as the input cable to the CJ pre-amp with the Audioquest Coral IC. Therefore, the Canare IC was used as the phono leads from the turntable, and AQ Coral IC pair as the cable plugged into to the CJ pre-amp's AUX 2 input. Again, no dice, the hum was still there. I thought may be the better made Canare IC was the culprit causing the hum because of poorly shielded RCA plugs. If I had two separate pair of 2-3 meter IC's, I would move the LP-110-phono pre farther away from the audio rack that the CJ pre-amp sits, and below it the BAT VK-200 power amp. I realize the BAT has very large power transformers
Lastly, the Moon Audio rep said that if his suggestions did not work, he would arrange with Music Direct who I purchased the LP-110 from, to send me a new one, and I would return my current unit back to MD.
That "might" solve the hum problem assuming the Moon phono box is somehow defective. However, U-Turn has a 30 day return policy, and I am at the point of returning it for a refund, and look for a new TT in the $600-700 range including cartridge. In addition, there are a few convenience features missing on the U-Turn TT, I was not aware of at the time of purchase. Everything is preset at the factory like tracking force, anti-skating, even the tone arm comes already balanced. However the counterweight does not have a calibration ring for tracking force adjustment and required getting a track force gauge if I decide to change cartridges. Also the anti-skate supposedly can be reset from its factory default setting, but there is no instruction in the one page manual how to do it.
I looked at a ton of tables before purchasing the U-Turn TT The product is cleverly built and is a "real" plug and play TT, but it has limited usable features Maybe, it is true that you get what you pay for.
