The Official Wharfedale Speakers Thread!

[mrw1zard]

Just have a "quick" question.
I am looking to replace my current 5.1 setup (Harman Kardon HKTS18) with the following,

Diamond 10.1 fronts (possibly 121s depending on when I get to purchase)
10.cs Center (again perhaps the newer center 101c)
2 10 sx subs

Questions
1) Do I replace the CS with another 10.1?
2) How would the two sub system improve or detract from my 1 sub setup now? (current sub is listed as a 10" 200 watt sub)
3) can i drive all this with a Marantz SR6006?

I am thinking about adding surround speakers later (or moving the 10.1s to the back and getting larger fronts - at which time I'll have to look at the power issue again)
Still new to good speakers, so just wanted to get some advice.

Thanks!
