Still Need Help

Ask for help last month and I’m still having problems. My system is Rega RP 3 turntable with the Rega upgrades. Exact cartridge. Rega Apollo CD player Rogue Metis pre amp and a Carver MT 1.0 T MK lll amp. Speakers are a pair of Source Technology 7211’s with two Source Technologies HV/S 10/500 Subwoofers. I have moved and gone from a basement music room with a concrete floor to a second floor music room. When I play CD’s it’s fine. But when I use the turntable I get a bad vibration from the subs. I mounted the turntable to the wall with the Rega wall mount. I had a cross stud put in between the studs to mount it to. Very little help if any. What should I try next? Change the feet on the subs? :SVS SoundPath Subwoofer Isolation Feet. The subs are on isolation pads.  I’m not a fan of CD’S miss my vinyl. Any help will be appreciated.

For a wall mounted shelf to isolate feedback the wall needs to be a structural wall or load bearing wall, otherwise the wall moves with the floor.

Other feedback issues, assuming the turntable is set up correctly, could be in room base response. Locate the shelf away from corners, and away from between the speakers - these areas generally have high base nodes.

Also check your set up, tracking force and antiscate, make sure the arm is mounted tightly - not loose. Check bearing and turntable feet are not loose. Make sure there are no rattles in the shelf itself.
