I was all set the buy the pioneer dcs-515 for the wireless speaker as my front room's layout is crap plus the old laminate floor (not speaker wire friendly) but pioneer have brought out a 525 version as far as i can tell its obviously more expensive and more powerfull and has a slimmer sub from the details provided on their site. But was wondering if any body had the 515 version is the rear speaker digital as its stating the 525 speaker is, but it is very vague in the descriptions of the 515 version. Or do you think that its the old company trick of teaking a few bits here and there i.e. sub slimmer, slighty more wattage but in general its the same system. Any opinions/Ideas would be welcome.
