@ David, I heard them in a Hi-Fi shop, but in a quite large (poorly designd for audio listening) room. Both speakers were connected to Cambridge Audio 651A amp, and Cambridge audio Cd player (cannot remember the exact model, but it was sme price level as the amp). I just switched the A/B source during listening the songs form Q700 to LS50 - so the comparison was fairly direct. I took a chance to listen to KEFs because its quite complicated in my region to listen to speakers, and listened even to Q300, but these did not impressed me at all (especially with direct comparison to Q700). I still believe that it was not the problem of amplifier, or CD player, but the problem of the listening room and slight noice from street, but my first impression of Q300 was ("hell, my 10 years old Philips micro system for 200€ sound better with the same CD!"). So I was offered to replace Q300 for LS50 and compare these to Q700. LS50 was a significant improvement over Q300 form me, but stil the sound in that particular room did not let me immerse into the music as expected, it was not so detailed, deep, real... even though I believe these speakers can play musc this way (hopefully?). Q700 sounded more adult, more sure, but as stated in post below a bit "too forward" and Im a bit affraid how such floorstanders would sound in my living room (5x4m - speakers need to be placed at the longer wall in almost corners). Im a bit affraid that Q700 are too much for such room (Im not sure with their bass), and perhaps LS50 too little (?) I definitelly cannot listen LS50 from ideal 2m distance, it will be at least 3m having speakers 4-4.5m from each other.... whats your opinion?
