For AV duties, I use the original KEF 1005, for stereo single-wired B&W 685. For a while, I used Wharfedale 9.1s for stereo but 685s are better suited for it.
The sound is unmistakably Marantz - balanced and detailed with solid depth and smooth mids. Treble can, at times, sound slightly dislocated - in that I must say I prefer 9.1's tweeter, but this is a characteristic of the speakers, rather than the 1601. It is nothing too detrimental, just a minor flaw in otherwise well-balanced 685s. For the money, nothing comes close to 9.1 imho.
