As much fun as it is to tweak my system, I prefer to keep the front end simple. I stream from a Cambridge 851N to one of 3 amps: Mark Levinson ML-23.5, Jeff Rowland Model 5, or Line Magnetic LM 150ia. These amps drive my TSW Apogee Duetta Ultimates. I also can rotate in Acoustat Spectra 66’s, Acoustat 2+2’s, Apogee Scintillas, or Apogee Mini Grands. I can custom tailor the sound to my mood by switching amps and/or speakers.
