I have a brand new unopened ifi micro iDSD Black Label for sale. This is my second Micro BL unit that I received as gift recently.
This a top-rated DAC/amp that can output 10V/4,000 mW@16 Ohm power in Turbo mode. It has plenty of power to drive my full-size planar magnetic headphones. Please check the ifi-Audio website for the full specifications. ifi micro iDSD Black Label
I may consider trading for a Massdrop THX AAA 789 amp in excellent condition plus cash on your side.
Buyer pays shipping and I will cover the paypal fee.
