…”I’ve had the headphone amp for a few days but the HA-160 is proving to be an excellent mate to my Grado PS1000 headphones. The amp is able to show what the Grados are capable of and vice versa. This is the first combination of headphone and amp that matches my audio system composed of Magnepan 20.1 speakers, Pass Labs 600.5 mono amps and Aesthetix Janus preamp.

The HA-160 and Grado headphones are capable of competing with an audio system in the tens of thousands of dollars and losing nothing to them which says a ton about this little relatively inexpensive headphone amp.

In any case I would highly recommend this amp to anyone looking for a world class headphone amp for personal listening”…
