The system, which includes dual subs, not just the Design 5. And the B&W in their room, which was a large showroom more than a "demo" room vs. my room which is quite small and treated with acoustic panels and bass traps. I found both the B&W and my era system display similar characteristics, each within their own venue, that I find pleasing. Both have full, rich midrange, clear but not overly bright highs and tight yet effortless bass. The B&W probably are, and should be, much better than the era in certain ways. Of all the speakers that I've heard, they are the closest tonal match to what I have, but I doubt the B&W would work in my small space. I count myself lucky that I've found a set of speakers that I like so much that I don't feel the need to upgrade. I was actually listening to the B&W to test the amp that was driving them and went home with the amp.
