" Oppo's HA-1 is a very flexible headphone amp and home theatre DAC/pre-amp and about spot-on for the money."
" The Oppo HA-1 headphone amplifier is definitely a slam-dunk for audiophiles."
" Worth auditioning at this price, but it needs to deliver more energy and excitement for the full five"
" I think the HA-1 is good enough to use as a reference, and in fact, because of its preternatural neutrality, it makes a good reference indeed. But more than that, I just plain enjoyed listening to music on the thing. And I enjoyed it frequently. I also enjoyed looking at it."
" Nothing on the market has a price to features and performance ratio like this. The HA-1 is in a class all by itself. Housing the 2nd best audio clarity in the price tier, Oppo has achieved something few others have and I seriously doubt anyone is going to offer another DAC/amp in this price tier that offers this level of clarity as well as 1up Oppo with even more features. Oppo shot for the moon and ended up on Mars, but the amp isn’t without faults, although it still outscored nearly every other sub $1500 DAC and amp I’ve ever used."
" If you have a good pair of headphones, you owe it to them (and yourself) to pair them with a good amp and DAC. And the Oppo HA-1 is a very, very good amp (and DAC). Highly recommended."
