Just an observation here, but????????

In vintage turntables, I prefer spring suspension augmented by the turntable being placed on rubber isolation feet. My Technics SL-1700mk2, which benefits from a non-resonant substructure which is spring-suspended, has its feet upgraded to the rubber-isolation feet from the brutish SL-1200mk2, which has no suspension whatsoever. The result is great. For my application anyways....  

Orpheus 10 how in the world is recording a album to tape, regardless of the type, going to make playback better.

A extra variable in speed?  Another transfer function?  Unless  I read the above post incorrectly, I am really lost.

Enjoy the ride

Tom, like many things in high end audio, it's difficult to explain, but easy to demonstrate.

Either high mass or good suspension can work, question is whether they do in a given situation.

I have one sprung table, a Sota Cosmos, and its is admirably free from environmental vibration. (A good way to test is to get out a test record with a blank side, lower the stylus on it, turn up the sound a bit and walk around the room or even stomp around - if you get nothing through the speakers you are doing a good job of isolation).

I have another high mass table, A VPI TNT, sitting on a heavy stone base about 4' high with a thick granite slab on top, situated near a wall, and it is equally unaffected by room/floor vibration. For suspension it has only four squash balls, one in each 'tower'...and no, I have not done auditions to see if orange dot (slow) or blue dot (fast) sound better than the yellows I have in there, but I intend to do so some day....

Then there are the guys that suspend their tables from the ceiling on bifilar lines so they hang in mid-air - and then stay awake at night worrying about air borne vibrations.
