Currently running JBL 590's with a KEF Q650C. Was thinking of selling my Q900's and Q650C. Looking to pair something with the JBL 590's. I was thinking possibly the Emotiva Airmotiv C2+. Not sure yet, still trying to find one that somewhat matches the looks of the JBL's while matching the sound as well. Not sure about the 520C. Does that nickname log u into the Corp Domain?
