Hey guys, Any impressions of these two sets of speakers - Wharfedale Diamond 9.4/9.C/9.1 and Celestion F20/F35/F10? They are selling for roughly the same, would hook them up to a Yamaha RX-V450. Use for HT and music, 50/50. Not too picky about music as it's background mostly. I can't seem to find many reviews online on either of them - just a bit on the Diamond's which says they're pretty good for the price. They also seem to go a bit lower according to their spec. Thanks!
