I have an Oppo HA-2 and will never part with it. I use it with my Pono, iPod Touch 6th gen 128gb, Sony NW-A45 and A & K 70 MK II. The Oppo HA-2 push's them all to their best. All my headphones sound amazing with it. Wish they did not stop making them.
Astell Kern Jr vs Oppo HA 2
Looking for sound quality comparisons between the Astell & Kern Jr and an Oppo HA 2 headphone amp used with the last version of iPod Classic which I already own. Will not be used for travel and the Astell holds enough music for me. Current headphones are Sennheiser HD650 but that could change.
