Isolation for turntables

I don't know if this is possible in your particular situation, but I bought a wall mounted audio shelf. I had the same problem, and now it never ever skips. It's not very fancy, but it does the trick. It's a steel frame (black) with a black plank of wood resting on small spikes. If you want additional isolation, I suppose you could always put the Townsend thingy on the shelf.

Another method is to put a supporting concrete pile under your house directly under the turntable - although I concede this is not always practical. Since the Oracle is sprung, then any additional compliant isolation will cause sonic degradation through creating nodes between the resonant frequencies of the two systems. Another method would be to find where the floor has solid supports, and put the turntable on top of one, or put it on a rigid plank that spans from one to another of the supports.

Two solutions, wall mount it, which is the easiest. If you have a crawl space or basement under the floor (joist and frame construction) it would't hurt to beef up the floor under the turntable. Those joists need reinforcement with a couple of piers and stringers running perpendicular to the joists or columns and stringers if a basement. This may not be practical in the case of a basement. Who wants an extra column or 2 in the middle of their basement? Without knowing all the specifics, this information is general but, you get the idea, your floor needs more support down under.

I went wild building a wall mount shelf for my P-25.I bought some heavy steel 18"long L brackets and bolted them to 2 2x4's which I then bolted to the wall.The bolts go through the wall to the outside where they are very tightly secured with nuts.On top of the brackets I placed 4 rubber grommets.On top of those a 16"x16" x1" MDF shelf rests and on top of that a Bright Star Audio Big Rock #4.Never had a problem amd the sound improvement was very noticeable.

Hi Jeff, First, you must learn to properly adjust your Delphi's suspension.It is without doubt, the finest spring suspension turnatble evr designed in terms of isolation from outside disturbances.You should be able to host WWF tag team matches in your listening room without missing a beat.When it's done right, the platter will not shimmy or sway at all but rather operate in a pure pistonic motion.You should be able to tap firmly on the clamp and it will settle in 1-2 cycles to an even, slow bounce at 3-5 cycles/sec and die away.Check to see that the tonearm cable is not fouling in any way. second,the best means of siting would be a lightweight,rigid wall support like the Target VW1 or older TT1 and original Sound Organisation wall mounts.Second best would be a similarly principled Target,Standesign or Sound Org floor stand.High mass and heavy weight will store energy and re-release it back into the system as well as energise supsended flooring like a tramopline.You want a low mass design so that vibrations dissipate quickly and thus intrude less into the music.A small amount of blu-tac on the lower portion of the legs is all you need for damping.Avoid sand and lead filling of the legs like the plague as it will slow and muddy the sound.
