Product Reviews

  • "good power amplifier" by jojdc1122 on 6/1/2013
    Overall: 4 out of 5

    the pla900 power amplifier is vary well constructed, this two channel amplifier has a large power transformer....his unit uses unbalanced connections and i would say it puts out 150 to 250 watts per channel under 8ohms... and the weight of this amplifier is about 33 lbs... a few draw backs, it would be better if this amplifier had rear ear mounts, and true balanced xlr inputs and outputs, plus binding post for speakers for direct wiring... as stated, this amplifier is worth the money for value and quality...... it would be nice if steller labs comes out with a much larger power amplifier in the future that puts out at least 500 watts or larger under 8 ohms....
