But you made it obvious and clear that you much preferred colored (less accurate) and "fun" sounding speakers. Thus the reasons why you prefer the 685 over the Sierras. If you like "fun" speakers I'd also recommend Klipsch RP series and Monitor Audio Silver 1. Neither speakers are accurate where the Klipsch are super dynamic (much more dynamic than the 685) and the MA produce a very unique and interesting sound that you won't find from any other speakers. Both speakers I would categorize as "fun" which you may also like.
I'm surprised you are comparing B&W to Klipsch. When I was looking to buy speakers a few years ago, I tried several ones including Klipsch, Wharfedale, JBL, Jamo, KEF, Magnat, Focal and many other brands. Klipsch was by far the worst for music and JBL was next. In HT applications their deficiencies are not that well noticed.
Finally I ended up getting the B&W 603 S3 based set-up, for the accuracy in producing string instruments. (chose it over the 684 S1). Magnat was the second best in my opinion. I don't have experience with Monitor Audio, but I heard the Silver series is good. I don't live in the US, so accessing ID brands like Ascend is not possible. But all ID brands are automatically better than B&M based brands is not a valid argument.
Fast forward to present day, I recently built the Linkwitz Pluto 2.1 hoping that I will replace the ageing B&W 603. Surprisingly, the B&W's are quite good on their own right compared to the Pluto's, which are considered to be unbeatable in their price range. The Plutos completely disappear and have better detail. But the B&Ws have a musical quality to them, that can only be experienced; hard to describe.
So whoever is on the fence, its another vote from me for B&W. Personally with a $600 budget, I will skim Audiogon for a used pair of 603 S3, which I felt were better than the 684 S1.
