 What
Hi-Fi? Sound and Vision's verdict on the Solo Headphone Amplifier
in the 2004 Ultimate Guide >> |
A Professional Headphone Amplifier
The
excellent resolution of the Solo Headphone Amplifier makes it first-choice for editing suite and
studio work...
The Solo headphone amplifier is the choice of several studios and editing suites
for one very important reason - the Solo headphone amplifier makes it easy to hear the editing cues. These
are musical cues that are part of the performance, but they happen so quickly
that some lesser headphone amplifiers make the editing suite's job very
difficult indeed. The wide-bandwidth performance of the Solo headphone amplifier
reproduces music with the
highest resolution. Coupled with its excellent dynamics, the Solo headphone
amplifier is the obvious choice for the professional user.

What Hi-Fi? Sound and Vision Solo Headphone Amplifier review, October 2004
"Slee's Solo solution is magical"
"...the Solo Headphone Amplifier delivers a rich and insightful sound that puts a magnifying
glass on every aspect of a recording... most of all it will communicate
exactly what the artist intended - the music..."
"An example? Tracy Chapman sounds awfully world-weary on Over You
from her Let It Rain set, which is nothing abnormal for her, but the
Solo also manages to pick out a little edge of hopefulness in her voice -
something most other kit can't do. That subtlety is enough to change the
track's message."
"Whether you play Stravinsky or Massive
Attack, the Solo is a superb all-rounder that gets to the music's heart"
"Verdict: If you are serious about headphones go and have a listen to
the Solo - and be prepared to buy it there and then"
