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!
