I am in the midst of putting together my sound system--much is still on hold due to shipping time (I live in Kazakhstan). I have B&W DM610i speakers for my fronts, and I have a pair of B&W DM302 speakers I was planning on using as my surrounds. But, I just saw a good deal on a pair of B&W DM600i speakers with a DM600 ifs center speaker. Since the DM600i speakers are the closest relative to the DM610i, might it be better to have these as surrounds for a good match? I can always use the DM302 speakers for my second room since I want to use the multiroom feature of my NAD T762 receiver. If it is a good deal, should I jump on the DM600i speakers? They will also match the DM610i speakers in ohms (both are 4 ohm nominal impedence). Your suggestions are welcome. Perhaps the fact that the DM610i and DM302 are both B&W will be enough to ensure matching.
