As stated above, I've got the Prometheus speakers and I'm driving them with a Clari-T that's been upgraded with stepped attenuators, a sub output, and better capacitors. I've also got a Scott Nixon DacKit that Vinnie built for me, this is important as the whole chain is basically dead silent. The speakers are phenomenal, if you can build them and tolerate an incredibly long burn-in period (mine sounded so bad at first that I literally wanted to burn them) they are IMO unbeatable for anywhere near the price. Only speaker I've heard that I'd consider an upgrade would be WLM's, and they're way over $10k.
If you want any specific info on the speakers or how they mate up with the Red Wine Audio stuff feel free to send me a PM. I'm in Europe at the moment, it might take me a little while to respond but I'll get back to you.
