I had a pair of original Offrandes for a couple of years. I ultimately sold them because they just didn't work in my small (12 x 14) room, but I think that these are a very special speaker design.
I tried a variety of amps with these speakers, but certainly not everything. I believe that most of the amps you mentioned will work well, but I'm not sure that the McIntosh is the best match for the Offrandes. But I'm admittedly not a Mac guy. I would also never discount Bob Neill's recommendation, but I hae no experience with Blue Circle gear.
I think that your selection of an amp needs to start with an analysis of your room, where you will place the speakers and what you expect in terms of bass response. The Offrande family is not a bass giant, so this may influence your decision.
I was very happy pairing the JMR speakers with my Audio Note OTO SE Phono, but again my room was small. I believe that Leben, Shindo and Jadis tube integrateds would also be a great match. I wanted to try the CJ CAV-50 but never had the opportunity.
On the SS side, I ended up using another French product - the Atoll IN100. I bought this as a dealer demo for a great price and I found it to be excellent. But I would almost certainly choose the Pass Labs INT30 if I had the budget for it. It's a fantastic amp, as long as your room isn't too large and/or you don't need to play overly loud.
Good luck
