Asking price is for the amp only, shipped in the U.S.

Buy the amp/DAC bundle for $115 and I will include Straightwire 6" RCA cables that are perfect for stacking these.

An affordable classic desktop headphone amp/DAC stack that was (is still?) very popular in the head-fi community. It was a staple in my computer audio headphone setup for a long time and was used during many of my headphone reviews. The JDS Labs O2 headphone and OL DAC is a surprisingly good setup that can power a wide range of headphones and has excellent bang for the buck. This unit has both USB and Optical inputs on the DAC and the Amp has the rechargeable batteries inside, but I honestly never used the unit when it wasn't connected to power.

These have many hours on them, but they are very well cared for and look practically new (to me). They've been in storage for more than 2 years and they deserve a good home. I hooked them up and they still sound great. Headphone jack has some minor wear but grips cables snug.

Will ship in original boxes.
