Conclusions
Video marketing material only talks about improvements in drivers. That seems to be there. Alas, decades of research into what makes a good sounding speaker was ignored with poor integration of drivers, multiple resonances and poor directivity which result in "proper showroom" sound but nothing you would want to live with. I don't mind throwing a filter or two at a speaker to make it sound good. But this design needs way more than that. You have to become a speaker designer, doing the work that the company was supposed to do. And that ain't right.
I can see how some subjectivist reviewer would fall in love with the clean and low distortion highs and call it an audiophile experience with micro detail, imagine and usual buzzwords. But that is not a good diet for an audiophile. You want a speaker that gets out of the way and reproduces what is in your source faithfully.
Just to make sure I was not in a "bad audio mood," I swapped the 607 S2 for a Revel M105. Wow, what an improvement in overall tonality, feel of the speaker and quality all around. Yes, it costs twice as much. But it shows you what proper sound is like. It does justice to your music whereas the 607 S2 doesn't. It latter spits on your music and says, I am going to tell you how it should sound.
Is the 607 S2 the worse speaker I have heard? No. There is some good engineering in the driver. I hope some of that rubs off to whoever did the system design of the speaker.
The marketing material said they have sold one or two million 600 series speakers since inception. So I suspect the management if it sees this review is going to be flippant and continue to ship subpar speakers to their customers. It is a bit depressing that what sells is dominant factor in speaker business and design.
Needless to say, I can't recommend the B&W 607 S2 Anniversary Edition. There are plenty of speakers at low prices that do better.
