@rauliruegas , Darn Raul, I just got a new turntable and you are already selling me another one. As a spare I want to get a Dohmann Helix:-)

tonight i’m bringing out some of my big classical guns to really test the mettle of the FCL. and i am blown away. https://elusivedisc.com/grieg-peer-gynt-numbered-limited-edition-180g-45rpm-2lp/ this thing is so fast, crazy unimaginably fast. and it does not break a sweat even a little. for the last 90 minutes i’ve sampled some formidable pressings i had solid aural memories of, and those memories have been laid to waste. a caution......since i cannot switch inputs i’ve not tried my other arms and cartridges without unplugging phono cables, so no A/B’s for now. therefore; i reserve the right to walk this back later when i get around to trying my other choices. |
Mike, it is simply a unipvot bearing. The field coil is used for stabilisation - stop the wobble. The advantage of the field coil over a magnetic field is that the field coil uses a constant current source, From their site -
It's designed to take advantage of the unipivot, which has low bearing stiction, but address the inherent instability of an undamped unipivot. If I recall correctly Martin Colloms tested and reported that the Naim Aro had the lowest bearing stiction of any arm he had measured. Other methods of stabilisation include having a centre of gravity below the pivot ( not ideal on warped records ),fluid damping ( examples Mayware/Moerch/Kuzma ) and magnetic fields.

i've owned a few unipivots; many years ago (late 90's, into 2001) i owned a couple of Graham arms; the 1.5 and the 1.5tc. they were a bit wobbly. never owned a Phantom or Graham after that. |
Aside from the fact that the strength of the magnetic field and its orientation with respect to the unipivot would or could make a big difference, why is the FCL superior to the best iteration of the Graham Phantom tonearm(s), which use permanent magnets to stabilize the bearing? I bring this up only for discussion; I have no preformed opinion, because I’ve used neither tonearm. |
