I happen to be a bit of a Bowers and Wilkins fan-boy, but, really I just sort of stumbled into it starting about 10 years ago when I was looking to upgrade my front speakers in my surround rig. Was traveling to three different shops looking at KEF, B&W, and PSB. This went on for a couple years as I was doing a slightly less thorough job assessing the sounds than you are.
Finally, after a couple years of being a bother to the sales staff at these shops, the closest shop let me know that they were selling their demo models of a set of DM603 S3s and an LCR600 S3, and were marking them down 40%. I didn't even let Opportunity's knuckle hit the door a second time, and I bought them.
Yeah, my rig's a home theater rig, but it does a mighty fine job with two-channel audio as well.
My point? Not to recommend B&W over any other product. No, I'm just enjoying reading about your decision-making process.
Thanks.
