Lyra Lydian Beta, Rega hum?

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?

Marakanetz-so you've heard both tables?

Of course 'aint only rock and roll in the world' but why would I buy a table that didnt do it for me with rock when thats mostly what I listen to??
I listened to the 25 and the 1400.The 25 did it for me for what I was listening for.
This guy that started the thread wants help with his hum.Not to be told to 'dump' his table.If ya cant help him out then butt out and don't flame.
As mentioned above,the P-25 I.C.'s are internally grounded.The hum is not in the table/arm.

Jfreck is correct that the Regas ground through the RCA connectors, but I do recall somewhere that this sometimes is not adequate. Perhaps certain pre's and/or phono pre's need additional grounding as Jfreck suggests.

Perhaps you can locate another table (non-Rega)to borrow and see if the problem persists?

Saw your post and read a few of the responses so if you've heard this suggestion already- apologies. Hum is often a problem with MC cartridges due to RF interferences. Living in San Francisco for example, if you can see the hugh radio transmitter on twin peaks from where you live, chances are moving coil cartridge will have audible hum. This went away completely switching to MM cartridge
