Wharfedales are wonderful but under-rated speakers. Being hard to find, not many folks have actually heard them.
Besides musicdirect.com, you can also try onecall.com. They are a Wharfedale dealer too. Look for Diamond 10 series open box or demo units for deals. WRT your question about the 10.1's, they are a great budget bookshelf for the money competing with speakers at far more cost. I once had a full 5.1 set of Diamond 9's and sold the front three to a friend. I still get to hear and enjoy them at times. I kept the Diamond 9.2's and use them on 24" stands as my rear surrounds. The soft dome tweeters and kevlar woofers blend in well with my Vienna Acoustics front three - so much so that I really can't consider ever selling them and upgrading to Viennas for the back two. I recommend the 10.1 or 10.2 highly as they are suppose to be much improved over the Diamond 9 series that was well received.
