Any advantage or dis whn bolting rack to wall?????

Hey thank you very much, I am proud of the DIY Project.

you might want to rethink the idea of bolting to a wall unless it's a solid exterior supporting wall. Interior walls are typically just flimsey 2X4 + wallboard construction, which will flex along with the music's sound pressure against it - especially the bass frequancies. This would cause your whole rack to vibrate, introducing intermodulations back into the source equipment & essentially exciting a closed feedback loop.

Those who have attempted to even wall-mount a turntable shelf onto an interior wall surface can likely attest to the sonic disadvantages of such an approach.

good point, thanks Bob...guess it was a less than ideal thought.

I have to respectfully disagree with the comments re wall mounting. I have mounted my turntable on a Target wall shelf in two different listening rooms (same system, two diff homes). In one home the walls were typical, flimsy, sheetrock on metal studs; in the other (and current), the walls are very thick and solid plaster over incredibly hard and solid wooden studs, as found in most 110 year old Victorian homes. In both cases, even light footsteps made my tonearm skip (VPI/ET2 or Syrinx). Wall mounting not only solved the skipping problem, but cleaned up the sound to a very surprising degree. Bass was better defined and seemingly more extended, there is less grain to the overall sound, and even microdynamics seem improved. Yes, a wall will vibrate; so will a floor. Not only will the floor be, most likely, an even larger vibrating surface that the wall, but it is in direct physical contact with the main source of vibration: your speakers. If there is any way to mount your rack to the wall so that there is no contact with the floor (assuming that the weight is not a problem), then I think you would really be on to something.

Good luck.

Nice job on the rack, BTW. Looks terrific!
