They're hugely expesive. And non-linear.

They are not hugely expensive and they are very linear when operated
inside their design parameters. They also generally last forever in
small signal applications.

Changing a couple of resistor values inside the unit makes more sense if you know
how to.

It depends on the type of output circuit and may be listed in the
service manual as an approved mod for good results....oops, there
probably are no service manuals on Behringers.
