The Wharfedale evos are a step up from the Diamonds, althought the diamond 9's are newer speakers than the evos. The evos have wood veneer while the diamonds have vinyl. I believe the cabinets are similar, but some of the driver technologies are different. Some of the higher level Diamonds seem to share more with the top-flite Wharfedale Opus than the Evos.
Reviews seemto be pretty good on all of Wharfedale speakers. The evos aren't around much in the states. I will be interested in what you decide to do, and how you like them.
