L'explication de julian Vereker himself sur le puck :
"JV: There's one other thing which we've done which I think is again pretty much the opposite of everything that everyone else does. There seems to be, particularly in audiophile transports, people putting heavy things onto the disc to hold the disc down and so called "damp" it. We in fact do exactly the opposite. We have the lightest possible clamp or puck to put on top of the disc which uses a neodymium magnet — very, very powerful rare earth type magnet — to clamp it down. And it's very light and the clamp is arranged so that it only couples the disc with defined frequency bandwidth so it's not coupled tightly the way that other people's clamps clamp the disc to the...
PS: Coupled to the transport mechanism itself, you mean?
JV: Yeah, because the motor, the actual turntable motor — and it's direct coupled, a direct drive — is being fed with all sorts of pulsing currents in order to keep it at the right speed and of course there's a lot of vibration. Now you feed that vibration straight into the disc, which again affects the clarity of the eye pattern. So what we do is to couple it at a frequency where you can drive the disc, but not so that all the energy from the motor is fed straight into the disc. Now obviously the tighter you clamp it to that the more vibration you're going to feed in there."
