Hi all , hope you are all well and healthy. advise needed: I’m looking to upgrade my tv sound ( Samsung q85r) for better sound primarily for music but also to improve films etc. was thinking at first to get a soundbar as a quick upgrade but realise I would get better sound from av receiver and a pair of decent speakers. any advise on what I could buy ? Was originally thinking of spending about £500 but I realise I may need to up that budget. I’m toying with getting a Dolby ready after receiver but buying only two speakers for now to upgrade over time, is that a good plan?
