kef 104/2 or Thiel 2.3

I havent heard thiels, but ive always enjoyed the sound of KEFs, i dont think you could go wrong there. they have some pretty sweet imaging.

What is you amplification?

Those 104/2's are pretty awesome sounding speakers for the money. If you can find them on the cheap, I'd recommend them. Check on the age though, make sure the surrounds etc haven't detoriated with age. Also, didn't they make a small electronic crossover for those? It may have been the next model up, anyway, that little box made a difference in the bottom end. Went between the pre and amp or in a tape loop.

kefs for sure

In my opinion the best speaker Kef ever made!
