Hi, recently had the same dilemma. I also have a Cyrus 6a dac and previously ran a set of kef iq's, the detail was great but the sound too thin at times.
I demoed a lot if speakers, including the kef r range. I immediately liked the b+w 685 s2's. They sound good across a wide range of genres, indie, blues, electronic. I wanted a speaker that would produce a warm, deep sound with bass. These do the job nicely and so pleased with them.
I think if you get the combo right with Cyrus then the sound can be amazing. I also use audioquest blue speaker cable which helps keep everything balanced. Enjoy!!
