Congratulations on a great pair of speakers.
I don't think Magico recommends tubes or even class A Solid State with their speakers, but I would trust my own ears. I don't own the Q series, but do own the old Mini II. It's a difficult load, but I use Pass XA160.5 and think they sound great together. I know of a guy who owns the V2 and he uses the Pass XA100.5. I haven't heard his system, but he has a lot of exposure to Magico speakers and thinks they work well with Pass amps.
The Q5 is so transparent that you will hear the characteristics of the amp very clearly. Auditioning would be essential, IMO.
