I have not heard the B&W or Totem speakers, but would strongly suggest that you audition Dynaudio Excite X12's -Had mine for a week, and after app. 90 hours burn in- sound unbelievable- producing a sound much, much bigger than the size of their cabinets would suggest..

... available from a local shop that does their own service. A friend of mine has bought stuff from them and they've really taken care of him when his stuff broke/needed service. They provided him with loaner gear so he was never without music. I value this kind of customer service and like to support local merchants who provide this service. I also don't want to get something that will be so esoteric that it will be difficult to get serviced locally.
Thanks

That's a good line-up. Good brands/good sounds/good dealer/good reasons. Go for it. See if you can have a relaxed listening session or two to decide among the speakers. Take a range of music types (but all things that you like) to give them a workout. On CD's or good quality digital files (no 128kps).
