I’d K.I.S.S.
Stereo or 2.1 is less complicated so for your money you can find betterer gear.
Minx is supposed to be very good, part of the reason is they use a different sort of speaker driver within the satellites – deffo worth a listen.
I’ve not heard a musically accurate soundbar yet, but I have heard some that make a lot of noise for the money.
Personally, if you want to listen to music as well, or if overall the quality is more important then I’d look for a decent pair of speakers and a seperate amp.
Old amplifiers usually work as well as new ones, but you need to be more careful with old speakers as they age more and also can get damaged in more ways.
If you’re able to collect from Bradford I’m selling a very nice sounding but somewhat scruffy pair of floorstanders [AE109] with a massive sound. They’ve had a “service” – some new parts. £75 to you 🙂
