[US-CO] NEW Drop THX ONE AAA amp

Asking $150 shipped to the continental US.
Brand new, unboxed to verify functionality.
I have too many amps, this one has to go.

I suggested this model to a friend that was looking for an amp to supplement his DAC for his Beyerdynamic DT 990 (250ohm) PRO’s and he likes it.
