Which amp would you choose for a JBL 4367 setup?

I also own a pair of JBL 4367s, bought them right after they were introduced. I originally powered them with a Pass Labs XA 30.5, but soon upgraded to a McIntosh MC 452. The McIntosh was a much better match for them, this combination sounds incredible, especially at high SPLs. My room is about 17 x 21 x 8, the McIntosh never runs out of head room and the sound is clean and clear at any volume

Thank you for all the responses! Unfortunately, the Mac and the Mark Levinson is over my price range. I`d prefer solid state over tube, under 3500-4000 euros, used. Integrated or pre+amp(s). I don`t need DAC etc.

I paid $4250 for my used Mcintosh MAC7200 including shipping. Not too far from 4000 euros

MAC7200 was a steal. It`s more likely 6000Eur + shipping, used. 

I have the JBL 4367 and i've paired them with a Mcintosh Ma9000 and Ma6600 and while it sounded good it didn't sound amazing - a bit thin. I then powered them with, and bear with me, A schiit Freya+ preamp (I was skeptical at first) and a Magnus Audio ma400... it was MAGIC, seriously powerful and robust. you can get the schiit Frey+ for 800 and the Magnus Audio ma400 for 4500 through JM sound. Lastly I had it hooked up to an Audio Research VSi75 (integrated), build quality feels like scat BUT the sound was SUPERB. Best combo Ive found and actually listened to. Those mids were sooooo nice. There is a guy on Audiogon selling one new in the box for 4300. WELL worth it. Hope this helps.
