My system details are in my profile. I have Vandersteen Treo CTs now and want to make a meaningful upgrade. The amplifier is Boulder 1060. My long time dealer suggests Tannoy, MBL or Focal. While I have personally heard all three, I wonder if our brethren here may have other suggestions. Budget would be no more than $15,000, which believe it or not is pretty limiting. The really great ones are all much more expensive. I could consider used if in perfect condition. My sound preference is neutral, with as much resolution as possible, as little distortion as possible, and truly full range.
