Lyra Lydian Beta, Rega hum?

I have a Lydian Beta with a rega p25/rb600. Bat pre and phono stage. No hum at all. Got to be something you can troubleshoot such as Jim's advice above. Also, maybe a defective cartridge?

Also, I'm curious what you think of the TT/cart combo. Sounds lean to me...not a lot of body...bass is great and soundstaging is great. maybe my cardtridge loading is off or VTA-since it's fixed?

I know the rega arm is grounding through the RCA connectors. Might be a issue there with your preamp.

Sorry I can't help more...maybe try posting this on Audio Assylum under the vinyl section...maybe someone will know some tricks...or email sonic frontiers?
