Thank you for all the responses!
Part of what is making this difficult is that I am actually buying not so much for the GE’s, but rather what comes down the road (which could in fact be more GE’s). So the real exercise is what pairs well the Primaluna but also with a future pair of speakers in the $10k range or higher.
I am looking to add some power for that reason. Maggies are off the table due to my room layout, but just about anything else is possible. A Pass 250.8 is probably my dream amp and within striking distance used. But I’m not married to that idea. I know there are a lot of folks on here with more knowledge than I do.
