Ars Machinae Turntable - anyone has input?

Do you mind elaborating a bit more on the TT itself?

Yes, It fails on a number of accounts but it's worse failing is the tonearm. Unipivot arms should be avoided at all costs. For a cartridge to perform it's job correctly the tonearm can have only two degrees of freedom, up/down and left/right. Unipivots add a third degree destabilizing the arm add a torsional degree of freedom.
