I've just started listening to records and bought a Pro-Ject Debut Carbon. I LOVE IT btw. The IC cable that came with it has a ground wire. I have a pair of dh labs BL1 that I have and want to use but doesn't have a ground wire. My question is if I use my own IC cable, can I leave it ungrounded? If yes then my other question is do I also need to ground my int. amp to the phono pre amp?

Thanks,

Dennis
