I am upgrading my front L & R speakers from M60's to 6K's, this is prompting a reappraisal of my system & how best to enjoy it.
Our TV room is 2.7m x 5m with one end having the TV setup - currently a 77" LG G3, Sony BDP800, Humax freesat, HD 621, 568.2mm, M60's, 5KHC, 2 x D1500's with 2 x DSP33's as rears.
We sit 3m or so from the screen , the rear wall has (full) floor to ceiling bookshelves. When I get the 6K's the D1500's will go.
My only current music source is a Mac feeding lossless files to the F80 in the living room.
In the past I have used Airports to distribute music, but am considering a WiiM or WiiM pro as I will be able to use a digital input on the 568. The optical input is used by the TV.
I have a couple of questions:
- Is the WiiM pro a significant upgrade over the basic offering, is there a better (comparably priced) alternative?
As funds become available would upgrading the centre to a 5200 be a better use of the cash than getting a sub?
Sub-question (pun intended

) The room volume is circa 1270 cu ft, were I to get one for movie LFE what would you recommend?
Thanks, Nick
