So my saga has now finished...
After having the BV8-40 for about 6 weeks & not being over impressed with it, my B&O dealer (I cannot speak more highly of them) gratefully upgraded the unit to the BV7-40 which arrived this week, being so far from the dealer though I did have to set it up myself,(with a PS3, Xbox360, WDTV, and all the speakers etc!!!) Wow, you just gotta love those instructions from B&O!! But I am now over the moon with it, the picture is far better, does not suffer from the 'BV8 Opera effect'. The BV7.4 speaker is just the best :-)
The unit is a perfect replacement for my BV6-26 which is now in the bedroom.
Now I just have to go and watch some Blu Ray movies....
