…”I received the HA-160D today and so far it has been AMAZING! Even without the full burn in time, this amp has already been a huge improvement. I noticed the bass has tightened a lot, and the headphones are so much more transparent. Each instrument can be heard with clarity and separation.

I would recommend this item to any audiophile looking to get into the high-end territory.

Thank you for the excellent product!
