30 ft rca run too long for a phono to preamp?

As far as I heard, most cable manufacturers don't recommend phono cable longer than 2 meters. I would either better isolate the table or try longer IC between preamp and power amp. Phono signal is so low that it is susceptible to noise such as RFI.

Audiolui -- Although it wasn't made completely clear in the original post, and I too was initially confused, the connection in question is between phono stage and preamp, not cartridge and phono stage.

Hello Gentlemen, thank you for your responses.

Right now the stylus, when playing is approx. 20" from the side of the left Vandersteen. As I am getting a wobbling deep bass feedback as the volume get's up there, I have to assume that the tt is too close?
Please tell me if I'm wrong, and I will work on isolating from the speaker.

The floors are really springy as well, and after trying different isolation products from herbie's that I had on hand, I am thinking I have to wall mount the tt. I am reluctant to mount a wall rack in the tables current location, only to find the proximity to the speakers is still an issue. Without turning our living room upside down, The best place is 30ft away. What I am hearing is that is too long. I cannot move the preamp, it and everything else are plugged into dedicated circuits. So, upon reviewing your answers, I have 2 options. A 30 ft run, or a wall mounted turntable 20" from a speaker.......or sell it?

Thanks,
Mike
