Help! Deciding btwn several 2.5K spkrs

I've been listening to quite a few speakers in the $2,500 range and would love to hear any input on those I am considering--JM Lab Cobalt 820, Linn 5140, Kef Reference 2.2, Vienna Acoustics Mozart. I'm using a Linn Majik integrated amp, which is rated at 60 watts. I know that speakers are a personal choice, but it would be helpful to hear any of your experiences with these products, whether you think any would not match well with my amp, or if you think all of my choices are utter crap! Also, am I correct in eliminating from consideration all 4 ohm speakers due to my limited wattage? Thanks!!!!!
