VonSchweikert VR4JR vs Magenpan MG 1.6

I'm considering replacing my VR4JRs with the MG 1.6 combined with a Rel Sub. I've demoed the 1.6s in-store, without the sub, and have been quite impressed, but have not yet demoed them at home. It is a really close call for me and I plan to home-demo them in a month when I have the time. I would bi-amp the 1.6 as i have with the JRs with tubes (90 WPC)on the mid/highs and a SS amp (200 WPC) on the bass. Bi-wired (obviously) with JPS Superconductor Petites.
Meanwhile, I'm interested in the opinions of anyone who has heard both.
