"The $6,800 Coda No. 8 is very musical yet very detailed in ways that make me think that a fairer comparison would be my $13,5000 Pass Labs XA-60.8 monoblocks, which is a significant accolade for the Coda No. 8, as the Pass 60.8s are mean competitors costing far more money." - Terry London, Home Theater Review
At any time you can re-bias the amp at the factory so you can increase the amplifiers output
