btw I think in subs, Martin Logan is a sleeper. I tested 5 different brands and models and ended up with the 700 which beat all the other ones (Klipsch, SVS, Elac, Polk). It’s not perfect but way better than the other ones, blends in with my speakers smoothly.
I checked the prices for you, they look to be the same for the UK as for the US.
I would have tried Monitor Audio as I love their speakers, but it was out of my price range.
Also, from what I saw from darko, the KEF KC62 is probably cutting edge too.
