> think the TV is a bit too low - the speakers are at roughly ear height but it's more or less the top of the TV which is at eye height. So I was thinking of getting something to place the TV on to raise it up a bit, and then placing a centre speaker in front?
Something like this https://www.amazon.co.uk/FITUEYES-Floor-Stand-Adjustable-Management-Black/dp/B07RXNQXHJ
Will raise the TV and allow you to get the center on top of your cabinet

I have the bigger version of this stand for my 77“ C1 and couldn't be happier
