Disappointment with Pro-Ject...

It seems I'm late to the party on this one,  but my Project Debut Carbon Espirit SB has that dreaded ground hum issue, that I wasn't aware of when I purchased it.  I figured oh...maybe it's my surge protector...nope.  possibly my interconnects?  Nope.   New ground wire? Nope.  Different phono preamp? Nope.  And what sealed the deal was hooking up my old JVC hunk of junk deck I had lying around, and while it doesnt sound very good, it did not hum.   

I'm already a few months out, so can't return it.  Wouldn't feel right selling it with this issue  to fund something different like a Rega (which I should have just spent the extra money in hindsight for a P3) and it's a shame...it sounds lovely...it really does. but I'm at a loss and don't know where to go from here...I've tried every trick I've seen on every forum and nothing has remedied the issue.  Hate the feeling that I've wasted over 500 dollars on a defective product.  (Well, closer to 700, but the Ortofon 2m Blue I feel was worth the extra money!)

Any ideas or solutions?  I feel like I've tried everything!

@tablejockey No, however, I did have a spare IEC cord lying around (who doesn’t) that I had removed the ground prong from previously, tried that and same result, which I assume a ground lift adapter would achieve the same thing.  Tried that on my phono pre (where I'm grounding my turntable, as the turntable uses a switching adapter for power.

@sfall, my other gear includes a Vincent PHO-700 phono pre, Jolida JD301-BRC integrated amp in my signal chain.  Other than that, I have an Audioengine DAC/Bluetooth receiver.  Speakers are Infinity (can't remember the model off the top of my head) and my interconnects I'm using are Audioquest Tower all the way through.

I had the same problem, but oddly not immediately out of the box. After many rounds of troubleshooting with my local dealer I decided to do surgery and took the housing off the bottom and manually separated the leads and ensured they weren't touching any of the other metal components. That worked, idk exactly what the problem was. 

I've read in other forums that they have quality control issues. Good luck and I hope it's something simple and not TT related.

I went crazy for a long time with hum issue. Changed table,changed cart. played with grounds, cable etc all to no avail. Then one day while playing with this problem my wife ( my wife !) says "try lifting the table up " . I lifted the TT about 12 inches off its shelf and hum was gone!  Turns out my pre was right under the TT, and it was causing the hum. All I did was swap the pre and cd player in my rack and the problem was solved.
