#79 is the SVT.
Both amps were set flat for the comparison, so some of the differences could likely be EQ'd out. The SVT had a hair more growl and the Fuchs was just a tiny bit tighter. Of course, given the difference in the output section, the two amps "feel" a little different. I couldn't crank either one up enough in the house to compare natural breakup at volume, but my guess is that the Fuchs would stay focused longer than the SVT. One really cool feature is that it doesn't require termination - a speaker cabinet - so you can run it into a USB audio interface and record "silent" as well. I think this one is a winner.
