Mackie HM-400

VFM King for Home/Project Studios

This Headphone amp is simply the best for the money!

4 Individual Channels with 4 separate aux inputs, simple 2 band eq and plenty of power for both my Audio Technica ATH-M50x and my DT770 250 Ohm. Also, the inputs and outputs for the monitors have no noise and are completely passive so that they aren't affected whether the Headphone Amp is on or off.

Unit feels solid, only reason I put 4 in quality is the Pots are a bit jiggly

Best value for money headphone amp.

Got this for one of our smallest rooms in the studio. Probably the best option for its price range. Adequate connectivity options and most importantly, almost non-existent self-noise.

Not that bad.

Audio quality is good but i have some cons:

1. my unit had the MAIN LEVEL knob defective, it was distortioning the sound when adjusting the level, but a replacement is on it's way.

2. all the level knobs are STEPPED KNOBS, so you can adjust the level in steps. i don't know why they engineered it like that, because it's pretty hard to adjust your levels. one step could be too low, and the next step could be clipping, and you don't have any "middle option"

3. the knobs are wiggly.

As for the build quality the unit is very heavy and solid. It has 4 scews on the bottom, it will scratch your table/other equipment that's under it.
