Rebel Audio RebelAmp - Official Thread

The Singxer SA-1and the Rebel RebelAmp are both very good. At the moment probably my two favorite solid state amps from my collection. The Singxer has more pronounced highs which give it an airy stage presence. The Rebel is on par or better than the Singxer in every other aspect but then does two things particularly better. First, the highs surpass the Singxer by being smoothed out yet somehow improving refined clarity. Second, the entire spectrum seems as if there is more sound. That statement …

Many comparisons to Rebel will show up in the Rebel thread.
