I have a set of PM1, and unless I move to a much larger home and require something bigger, this might be the last set of speakers I buy for a long while. I went through upgrade-itis for a few years, going from B&W 704 to 805 to 805 Signatures to Sonus Faber, all of which were very nice but never reached that point where I stopped shopping. After selling everything off and going with a cheap set of Mirage Omni-poles just to have some music (at a much lower investment), I decided to take one more shot at music happiness and bought a set of PM1 with matching stands. I absolutely love them - the bass is superb for such a small box, the highs are smooth, and the best compliment I can pay to any set of speakers is that these don't color the music. With all my previous speakers I got the impression that I wasn't listening to the music as it was recorded, or as it sounded live in the studio, rather I was listening to that particular speaker's interpretation of it and that interpretation altered the music somehow...like hearing an anecdote from a friend of a friend, and the story changes a little more as it goes from person to person, you know? I guess the best way to say it is that if the artist were in my room, playing the song, it wouldn't sound any different than what I was hearing on the speakers.
The real reason I wanted to post a review was to commend B&W on their service...yesterday my cat knocked a camera off a coffee table next to the speakers, and it was heavy enough to put a large gouge in the base. I emailed B&W customer service, and with one email reply and one phone call (for my credit card number) a new base is on the way. What makes this surprising is that the base is not on their parts list - they don't normally sell them separately, but I got lucky and the rep was able to find one for me and it's on the way. This is the 2nd time I've been helped quickly - the first time I needed a new set of foam plugs and that also took one quick email and they were in my mailbox. Great speakers, great service, kudos to B&W.
