    There's the Transient Attack, MOSFET, HA3500c....are they all the same? Is one more desirable than the others?

    Hmmm...Not sure. My "Transient Attack" is black faced instead of silver. Otherwise looks the same. It might be all marketing. They are good old amps and cheap. Good to keep as a backup or primary amp.

    Been around a long time, and like any product, it gets an occasional facelift or extra added feature.
