I own these amps. If you want amps that have the midrange and highs of the best tube gear along with the low end control and bass of Krell or Levinson these are the ones Wonderfully musical. Tonality and definition especially in the most challenging bass areas. You can differentiate all sorts of different bass. I am fortunate to be able to afford to put whatever sounds best into my system. I own the Lamm's. They SOUND the best.
