The original rubber shock-absorbing feet can be replaced with sets of opposing ring-magnets – ‘Mag-Lev’ (magnet levitation) feet.
To my humble ear, this is a significant advancement and highly recommended.
Forget spikes, cones, ball bearings, metal, carbon fibre, mechanical diodes, magic crystals….
Also a nice match for the Salvation’s magnet levitation platter main bearing.
The ring magnets are supplied fitted to black Delrin upper screw-in blocks and within aluminium lower ‘feet’.
The rear foot requires a little more care and force to bring together the two opposing, stronger double-magnets.
The Salvation turntable weighs over 20kg and the magnet levitation air-gap is only 0.5 to 1.5mm. However, it will spring down and up freely with downward force. There seems to be no contact friction or noise, just levitation!
- Dynamic Range is expanded, especially extending downward – allowing finer resolution of low-level detail, eg. vocal inflections, vibrato, etc. (Maybe what Allen Wright referred to as DDR – Downward Dynamic Range.)
- Music seems to ‘float’ – is more ‘ambient’, with more ‘air’, more background ‘quietness’.
- The ‘sound picture’ appears more expansive – more height and scale, an acoustic space populated with more detailed sounds.
- Tonally, Low Frequencies seem unaffected, but High Frequencies are more ‘resolved’ in finer detail – more HF ‘presence’. Some areas of upper midrange or HF fatigue or harshness on occasional records, have disappeared completely.
- Music seems more ‘live’, with more ‘projection’, ‘snap’, impact – clearer ‘leading edges’.
An excellent overall upgrade. A step closer to real live music!
My feeling is that Mag-Lev suspension could be beneficially used under other hifi equipment – providing excellent isolation & control of resonances.
Update (19 Oct 2016):
On our wooden floor, foot-fall ‘bounce’ problems seem to be much reduced also, with these turntable feet in place.
