spring loaded platform non-suspended turntable

In MY experience, non suspended turntables need a solid foundation to the center of the earth... Spring aids, ruin the sound.

Fingerpaws...oh yes you do have acoustic feedback...its just not at a frequency that you can call it that..however, it is blurring the sound coming from your turntable. Your fix (given the springy floor), is to mount a shelf on the wall for your Classic - affix it to studs. ( had one of those VPI spring things too). Get it off of that.... Get Bearpaws to replace your mini feet, and be delighted at how much more clear sound you get...more definition, more bass, clean, clean, clean.

Pryso....I suspect that you are right, but remember too that sound travels as well through springy floors (and walls)...low tones travel unimpeded through windows (listen to the delivery trucks going by), but the glass is reflective of the higher frequencies....(cover all windows and/or close the draperies to hear the difference in the room. My suggestion of mounting a turntable on a shelf mounted securely into the wall studs eliminate a surprising amount of vibration transmitted via springy wooden floors...no its not perfect, but I have frequently been surprised at how much better the performance of turntables on walls is improved. Certainly this is only a suggestion and you are encouraged to do as you see fit...but if you try my suggestion, it very well might surprise you too. My recommendation of Bearpaws to replace the mini feet still apply.
