I ordered a pair of Wharfedale 10.2's and a CS center. The center should arrive tonight, but the 10.2's are still a few weeks on backorder. I've read seemingly every review for the Diamond 10.1's and they all claimed these speakers to be amazing. It's really tough finding information about these speakers though, and user reviews all seem to praise the 10.1 as well as the 10.2's.
Wharfedale manufactures all of their components(or so I've read), so they're prices are a bit lower than comparably performing speakers. This is everything I've gathered from reading online reviews though, as I have no experience with how they actually sound. I will know soon though, and will be able to directly compare them to the first gen Pioneer floorstanders and bookshelf speakers.
I looked at Wharfedale Diamond 10.2's, Focal Chorus 706V's, Kef q300's, Def Tech sm55's and lots of other speakers in the "$500 per pair" range. Since I couldn't audition them all I am going off of reviews and will try to audition the Wharfes with the Focal 706v's.
