I just installed a Lyra Helikon mono on a spare armwand for a Graham 2.2 The sound is really present compared to mono recordings on my stereo cart (Benz LP) with the preamp switched to mono.
I have been thinking about why. The best I can come up with is that there are phase errors in the mechanical process of pick-up from the groove, and that these are eliminated - or greatly reduced - by the geometry of the mono coil vs. the stereo coil(s) in the cart. Less degrees of freedom, less error.
