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

One of the biggest factors, in belt/tape/ string tables, is platter mass.  This may be are ears hearing micro speed variations.  Large motors are also very influential.  Yes they can even be noisier (isolate from table).

Well just a couple of ideas if you build your own or things to look for when buying.  All theory aside listen in a system where parts or whole turntable can be switched around.  This is where the adjectives stop and the rubber meets the road.

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.

Orpheus 10

My ex wife work at Teac in 1975.  Lots of my friends had reel to reel tape decks.  Straight vinyl always sounded more real than vinyl to tape.  Now master tape before vinyl could be a whole other game.  Good news about her working at teac was I got Acuphase and Micro Seiko below dealer cost.

If your vinyl system is dailed in having the tape mellow it out is not a good thing.

Enjoy the ride
