How much do they really differ, does anyone know?
I had a brief listen to the 685 in the store (along with the 686's which didn't impress) and the 685 sounded really, really nice. As for reviews go, I've read nothing but raving reviews about them.
Thing is, I'm a student, and I'm on a thigh budget. On the internet I found a nice deal one the 601 S3's, a NIB pair. The difference in cost is about 250-300 euros for two speakers.
Are the 685 really that much better, or are they just a slight evolution of the 601 S3's? Anyone care to share their thoughts and impressions, much appreciated.
