For what its worth, I just completed an extensive in home double blind a/b test of the Ascend Acoustics Sierra Towers with RAAL against the Bowers and Wilkins 702 S2. My results can be seen in full on AVS forum. I chose the B and W in the end. For Jazz and all the B and W would really be good but sounds like your budget can accomodate something better than this 3-5K range.
Speaker recomendation
I just bought a second home and the room where the new system will go is quite large (60’x20’) with a wall of windows. I’m looking for a pair of speakers that will be more for listening in position close to the system but that can still move enough air for when we have lots of people over. Budget is about $10-15K for an amp and speakers. I have a Moon 340i but fear it doesn’t have enough power to move the speakers I’ll get. I was thinking about Golden Ear reference but my wife and I are more classical and jazz listeners and these are better for rock? Suggestions appreciated!
