Hi all! Newbie here ... Fantastic forum, it's been an inspiration and an excellent source of info for me so far. Not to mention an instant wallet-emptier. I've just taken delivery of some new shiny kit, but I've yet to set it up . . . Pio434 panel Pio501 amp Pio686 dvd MK K5's (fronts and centre) B&W CCM65 (ceiling mount rears) The demo I had with this kit was fantastic, but since delivery I've had several opinions saying that ceiling-mount rears are a big no-no, both in the installation and sound reproduction stakes. Does anyone else here have an opinion on them? Or have something similar installed? Much appreciated.
