So let me ask you what is the big diff btwn a high end zapco type of
an amp and my MTX ? I looked at the specs and they are incredibly
underrated. THe amp comes with an actual test spec sheet with numbers
like 56w/channel x 4(4ohm) instead of the 25W it's rated at and THD at
.016 instead .1

The difference in sound? Well, if we're talking about a Zapco with
equivalent output power, there is no difference. I don't have the data to
be able to tell you which is the more reliable amp in terms of repair rate.
I've always had good luck in that respect with both amps. Very good luck in
fact.
