Review on Enhanced Sony PHA-2 Headphone Amplifier for Superior Performance by Chris Walker

Didn't realize it would cost $. Couldn't there be such a big difference? Yes there is! My first audition was Hillary Hahn Bach's Concerto for Violin, Strings and Continuo in E Major 1st Allegro. The dirt is gone! Crunchy, beautiful. The second audition was Keith Jarrett's Bregenz, May 28, 1981, Part I. Again, a crisp, clear sound. clear clean sound! Oh well, I guess it won't come back!
