Honestly, the best brand is the brand that you love listening to and end up keeping These are all exceptional brands, it is what you end up happy with that would be the best. Have you listened to any of these?
Ryan...If you can get a copy of the November issue of What Hi-Fi Magazine, they have a whole buyer's guide section in this issue, it may prove helpful for you. The best advice is to listen for yourself and go with what sounds good to you. I have Wharfedale Diamond series and they are superb speakers in a budget price range. You can even pick up the new Diamond 9.1's for the price you are willing to pay. Good hunting!
