Hello all, I'm having a loft conversion and would like to start planning for some new equipment to go in it. I'll mostly be using the room for gaming with a PC to actually get 4k resolutions. The room is roughly 5.5m x 5m. I don't know much about surround sound and the differences between 5.1 and 7.1 or maybe there are even more speaker channels ? I have the space for lots of speakers and I could wall mount them or have free standing, that's not an issue. I also do some DJing and the decks will go in this room too so I'd also like to connect my mixer upto the new amp (XLR outputs on the mixer) and the speakers will need to have some power so I can get plenty of volume without distortion. 4K screen size needs to be at least 50" but not more than 60" I also need advice on cables both HDMI and speaker cables. I can stretch my 2k budget a little bit if necessary. Cheers, Lee.
