Update: I basically realised that I needed to get the TV sorted first. There’s no point doing the rest if I don’t have a TV that properly supports the sound system.
I went out with the intention of picking up an LG C1 55” OLED from John Lewis, but what I actually got was much better.
There was only one LG left in stock and it was on display, so I got chatting to the sales rep, and they pointed me towards the Samsung S95 55” OLED. List price was £1599, so much much more than I’d budgeted for, but they tipped me off that they had a customer return available. The customer had opened the box but realised they wanted a larger model. Price was reduced to £1039 plus I get £200 cashback from Samsung.
£839 for a TV of this quality is an absolute steal! I’ve just got it set up and the picture is stunning. The difference between this and the outgoing set is night and day, so yeah, I’m very very happy with the outcome
