 Up for sale is this well cared for, single-owner Oppo HA-1 headphone amplifier.  These are somewhat of a "Swiss army knife" for all that they are capable of. 1) it's a headphone amp 2) a great sounding DAC and 3) can also be used as a preamplifier.

It's no secret that Oppo products have been held in vey high regard in the audio community for their great performance levels and affordability.  While we don't have the original box, rest assured we'll get it boxed up properly for very safe delivery to your door (check out our feedback as comments about packaging is mentioned quite often).
