Here is all my gear. What's the best combo?

I am not familiar with all the equipment you've listed, but the IMF paired with the Pioneer are vintage gold.

I run my Magnepan .7s with a Prima Luna integrated and I can tell you it’s not the very best marriage. I like listening to it but it’s a big notch down from other pairings. Stereophile magazine agrees with me. 

You've got some cool vintage equipment. Is it all working properly?

Yes Ruebent all work well. I guess I started along the vintage lines finding pieces here and there. I'm just now at a point where almost no piece was specifically chosen to match any other and I was wondering where to go next.  I probably don't aim for hand-in-pants elitism, but am trying to ascertain best combo from what I've got or I could buy one other item if necessary . Yes I can listen, and of course have,  but there's a lot of experience out there to consider and that's what forums are for. 

The only advice that I find worthless is the "sell it all" trolls. I just want some friendly advice. 

@mid-fi-crisis  - Are you trying to put together one "best" system? Or are you trying to build multiple different systems for different rooms/locations? What are you going to do with the leftover equipment? 

Also, is your Prima Luna the Integrated Amp or a power amp?
