I've heard some Tannoys and really liked them. I don't know the models, I'm afraid.
Agree with Pogre here. You won't find Sound Quality in the electronics so much unless you are shifting from a very inexpensive unit to a mid-level and above... and even then, It might take a time difference of 10 yrs with technological upgrades to really make a significant difference in SQ.
I fully enjoy my surround setup and have no qualms recommending pursuing that if you are interested. I'm music first and listen to some 5-channel audio. Overall, maybe 90/95% Music to HT! I'm still going to install Atmos though.
I'd recommend making a list of your goals and options, and doing some research around that. look at you speakers and learn how much power you need to achieve the spl level you want to listen at. Audition some speakers for fun, just to hear how they sound compared to yours. Read some reviews to learn how those speakers are described... don't believe the review though! Rather use the reviews to help you form an opinion based on comparative listening and your own experience!
That, to me, is where this really starts to get fun. When you know the sound you like and can pursue those speakers and build a system around that!, that is when you are getting it!!!
