I am buying all the equipment with the speakers. So far my favorite amp I have demoed is the Music Fidelity M6si. I also demoed the Bluenote Node Icon streamer which sounded great to my ears.
I listen to a wide variety of music including electronic, classic rock, indy rock, hip-hop, orchestral music etc...
Room is 460 sqft with 17ft ceilings.
I am willing to buy used.
I listened to some Planar Magnetics but the ones I listened to were way out of my budget, ~30k Martin Logans. I was attracted to the 502SP's because of the dual concentric driver and their downward-firing bass port. From what I read they have a wide sweet spot with great offf axis listening. I confirmed this when I demoed them.
