absolute phase  post #1 of 109 Thread Starter  This ought to
spark some lively debate...  So i was looking thru a few OTL
tube amp schematics and i noticed that virtually every tube
headphone amplifier inverts phase. A quick glance at a number of
solid state units and none of them invert phase.  So that got me
to thinking whether or not absolute phase really makes a
difference. Certainly many of the record companies go thru great
effort to maintain correct phase, especially on classical
performances so there must actually be something to this. The
first high end grado headphones had phase switches.  So when
comparing a solid state and a tube amp at the same time, some of
the differences you hear may also be phase related.  Amplifiers
