Those old ADS speakers were real gems. I still have a pair of 1290's in my HT system. I agree it may be hard to find a modern equivalent. You might want to help us out with what your 1090's do that you really like and want to capture in a current design. For instance, there are two aspects of the old ADS line that really appeal to me. The tight, fast bass, and the overall timbral accuracy. In those two respects, I find them similar to Magnepan speakers. In fact, since 1984, I have used only ADS or Magnepan speakers in my main rig.
