For me the HA-160 headphone amplifier is the very essence of what high-end hi-fi should sound like. With the Sennheiser HD650 this thing hits like the proverbial sledge hammer in a velvet glove, if you like your music with a bit of kick to it you’ve come to the right place.
It is very rare to find an amplifier that has such extension, authority and control – and yet manages to remain so calm, composed and detailed.

Over the two years that I’ve owned the HA-160 I’ve never felt the need to exchange it for something else, and in my case that says a lot.
