Amherst audio / Bob Neill carries the Reynaud line. Bob's a real nice guy and I am sure will answer your questions.
I owned an Audio Refinement Complete integrated (YBA owned) and JMR Twins mkII's for a bout 5 years. AN amazing combination, always extremely musical and non-fatiguing. During that time, I also had JMR Cantabile floorstanders and a YBA Integra DT around for a few weeks on loan from a friend.
Simply put, YBA and JMR equipment make beutiful music together.
If you wan to go one better(or different) try anothr French electronics maker's amps - Audiomat. Their integrateds are tubed and take JMR speakers to the next level.
