My rack is a beauty, bentwood frames, curved cornered glass shelves, each isolated above it’s wood frame, but the end supports were physically stupid.
Combine that with the fact the floor is not only springy, it is not level.
If the rack and all the weight is slightly tilted, the floor vibrations will get that entire off-center mass moving, not just small vibrations transmitted to the TT.
So I decided to make it level, and extend the front and rear fulcrum points further. Notice the shadow under the original end support.
Wall Shelf.
Now, my rack and TT are level, but, like the song says, 'give me 3 steps', because if the floor is springy, it's not just vibrations, it is in/out of level more than if we had solid floors. A wall shelf would be better for me also.
That's why I have to take my JVC's arm lift to VAS, to refill the oil and slow down it's 'too fast' self lowering, give me time for 3 steps, especially when using light tracking cartridges. Now, that arm, with the lightest tracking cartridge, I know to turn my body, reach back, start the drop and 'Get Back'.
