Editor's note
If your headphones need real juice, this is where I would land. It has enough power and inputs to be the center of a desk, not just an add-on.
Why we picked it
Best for: A fixed desk with high-impedance headphones, a console or a TV feeding it.
1.5W into 32 ohms with three-position gain, plus optical and coaxial inputs. This is the pick if your headphone is hard to drive.
What we like
- + 1.5W into 32 ohms with enough voltage swing to control a 300-ohm headphone, not just make it loud
- + Three-position gain covers sensitive IEMs through demanding dynamics without landing between steps
- + Optical, coaxial, USB and RCA inputs let a console, a TV and a computer share one amplifier
- + RCA line output drives powered speakers from the same box, so it replaces a preamp too
Watch outs
- - Mains powered with no battery and no Bluetooth, so it is a permanent desk fixture
- - Single-ended 6.35mm output only, so a balanced headphone cable is wasted on it
- - Runs warm and wants clear air around it, which rules out a closed cabinet
- - No EQ of any kind, so tone shaping has to happen on the source
