I dealt with a similar issue years ago. Mounting the turntable on a shelf on the wall solved the issue. Best of luck.
Dealing with Vibration on 2d Floor of Home
Happy almost-Spring, A'goners! I haven't visited in a couple years, but I'm back to ask for your help.
By necessity, my audio room is on the second floor of my home. I struggle mightily with vibration from my own footfalls those of others on the second floor while my turntable is playing. Even my careful footsteps away from the turntable to my listening chair cause the turntable arm to jump. Likewise, "normal" footsteps of other family members in the hallway or adjoining rooms cause the arm to move.
I'm currently using a "flexyrack" with heavy 2" thick solid maple shelves.
A couple years ago I purcahsed a Symposium platform to place under the turntable, but that only mitigated the issue caused by faint, distant footfalls. It is ineffective against closer or heavier footfalls.
Shy of spending $$$$ on a state-of-the-art isolation rack, is there a solution for isolating the turntable without altering the sound?

@chayro I had my LP12 mounted on the wall under the stairs back in the day. Even with concrete floor and breeze block walls. Feedback from the bass. As you say the only way for the is wall mounting. |
I have springy wood floors, my TT is between/slightly behind the Speakers, so it's not airborne vibrations, just the 1st few steps away after dropping the arm. You problem sounds worse than mine. after making new end supports and leveling my rack (so all weight goes down, not even slightly forward))
my final solution was a set of isolation blocks
I just tried them, they worked. If they didn't work, I would have tried one of the Townsend platforms so many recommend here. However, the lighter you track, the more the floor movement is a problem. I do well with 2.0gm, and even 1.25 gm, but I recently acquired an OEM stylus for my shure V15VxMR which tracks at 1.0gm. I have to get in position to step away when I move the lever to drop the arm. I'm going to have VAS refil that lifter to slow it down like my Mission arm, drop the lever, stroll away, doesn't land until I'm sitting down. Another issue is compliance, make sure your cartridge and arm are compatible. My Shure is a high compliance, matching better with lightweight arms, like the SME 3009 I used to play it on (I didn't know). I have it on a medium compliance arm, and if a large or sudden warp exists, it sends that heavier arm and cartridge (with only 1.0gm TF) flying. Thus, it is more susceptible to floor vibrations, which you can think of as a series of warps. |
