Additional info:

Bought this amp in May and used it with some Dyns with great results.

Reason for sale is I am getting into home audio and giving up some of my car audio gear to fund the home audio rig.

You will not find a better amp at or near this price.

Also the fully regulated power supply is nice as is the ability to run a 2 way active set up.
