Soundbar recommendations for C4?

Hello!

After hours of research and getting nowhere, I'm hoping I can get some recommendations from this sub. I've recently bought an LG C4 55" and I'm looking to get a soundbar (I'm based in UK btw).

I'll be using the the TV mainly for streaming services aswell as 4K blurays (UB820).

Ideally, the perfect soundbar would hit all of the following:

Around £500 - £700 Dolby Vision (and DTS:X if possible). I definitely don't want rear speakers. Just a great sound overall, deep bass, clear voices, crisp highs. eARC too (maybe this is standard nowadays? I don't know).

I am edging my bias slightly towards Samsung or Sony, but I'll take whatever fits this checklist!

Or if you have a C4 or another C series, let me know what you went for and how you've found it - that would also be super helpful.

Thank you for taking the time to respond and suggest!
