The AKG HP4E Amplifier is an awesome studio solution, but of particular interest to any would-be headphone reviewer. Â With the ability to input two different sources, as well as four-channel output, the benefits are clear. Â So for $99 is there anything that doesn’t recommend this beast?
AKG HP4E Review
The AKG HP4E is simple. Â It’s a no-nonsense amplifier that can handle up to four headphones. Â While also handling two different audio sources. Â Yowch. Â But seriously, you wouldn’t know it was such a badass amplifier just from looking at it.
For one thing, it comes in such a plain, unassuming cardboard box. Â Inside of which, is a smattering of Styrofoam to help cushion the little guy. Â There’s a power cable, some interchangeable plug adapters (depending on where in the world you plan to use the amp), and that’s it folks.
But once you get a pair of cans and an audio source, it’s plain to see this is an A-B tester’s dream come true.
You simply plug in some headphones (each headphone can be plugged in with a 3.5mm or 1/4” stereo plug), adjust volume for each headset, and play some tunes.
Your audio source plugs into the back of the unit via left and right 1/4” mono cables, but there are jacks for four plugs (that’s two sources!)! Â So if you want to hear the difference between FLAC and MP3, MP3 and AAC, an iPhone DAC vs a Samsung DAC, this is an excellent solution.
As for me, a reviewer, this amp has now found a permanent place on my desk.  If you’re even considering this amplifier, track down a dealer and give it a test run.  The build quality is fantastic, the sound quality is fantastic, and the fact that it answers all your audio-testing prayers is fantastic.
