You might want to re-think the Arcam. They have a very poor reliability history.
As for speakers, you really have to listen for yourself. While all your choices are competent products, they will differ in tonal balance etc., so you need to pick one you like. No point asking others, since the electronics they are hooked up to will also make a difference (as will cables, rooms etc). All you will get is response from current owners of individual products.
My experience with HT speakers is finding a centre channel that works in my room. That's the really hard part. Then it's fairly easy to find the matching L/R mains. Totem have a few decent centre channels, how about RM and Epos? No point finding a nice set of mains you can't match (visually and sonically) with a centre.
