I have owned a pair of the Reference 4 for a few years now. I have also owned the older Reference series 104/2 and 105/3. The Reference 4 are a bit more full bodied. While they sound decent with any quality amp they really, really, really like a lot of good clean power. A quality amp will bring out the best in them so that may be an area you have to upgrade also along with your speakers.
How good are Kef Reference 4's
Does anyone have an opinion on Kef Reference 4's? Would you suggest another speaker in this same price range? Any input would be appreciated. Thanks all.
