The Emerald Physics speakers would probably be quite happy with Class D amplification, but the PiSpeakers and mine would probably perform their best with low damping factor tube amps. I can't speak for the Tylers or Opera Consonance speakers, but you can ask Ty directly and we can hope the Trelja, who is the Opera Consonance importer, will join in.
By the way, I second the suggestions of Dodgealum and Ditusa. Daedelus speakers are very lively and musical, and while I haven't heard the JBL 4435, in my opinion the 4430 is a genuine classic (and the big 4435 is probably even better). The Altec Model 14 and Model 19 are very nice also, if you can find a pair.
Can you tell us a little bit about the room the speakers will be going in? With some boundary reinforcement and/or room gain to warm up the bottom end a bit, I think more of these speakers would work well with your amp.
Best of luck in your quest,
