So i replaced a pair of Energy CF70s with a pair of 685Bs. After breaking them in, these speakers are AWESOME. Pairing them with a Yamaha 667 and a Parasound amp, the difference is immediate, and much better. Call me crazy, but to me after calibrating, they put out as much as the CF70s, with a bit wider dispersion as well. I can also crank these to reference and they will not struggle or get painfully bright like the CF70s did.
I thought i preferred the brighter sound (Axiom, CF Energy, Polk, etc) because it had a sizzle i liked, but these sound extremely smooth, no detail loss, and with no fatigue. Also, these reveal ALOT more than any other speakers ive owned. Testing various music sources, listening to Lamb of God's "Now Youve Got Something To Die For", its apparent the studio was a small one. I hear alot of other detail in other songs ive never noticed before.
Only real complaint i have is that some female vocals sound somewhat muffled, trapped. iiO's Poetica and Exit110 albums guilty parties. Maybe its her range, or maybe its the source material, but her vocals seem to get lost in some songs. Not all female vocals suffered like that but material on those 2 albums stuck out. But thats why you different brands of speakers.
Other than that, great speakers, and it has converted me to the Euro-type sound. Now i REALLY wanna demo other Euro manufacturers speakers, i.e. Jamo, and Wharfedale as well high speakers higher in the B&W spectrum.
