Balanced headphone amp with 4.4mm output, THX AAA 788+ amp technology along with dual dacs, the new ak4493seq chips.

There is a multicolour light behind the volume dial, with blue / yellow / green indicating the file bitrate that is playing.  Use a computer, phone or ipad as a source via usb.

Great sound that paired down my desktop step

Used this to drop a DAC/amp/splitter setup I was using previously. I ended up with much cleaner sound, more power and the easy of a switch to go from my headphones to my speaker amp. As always headphone bar shipped quickly and everything showed up perfectly packaged. I'm not sure you can beat the sound quality and utility of this device without spending a fair bit more money.

I have a lot of headphone amplifiers. This one in particular is doing something amazing to my planar headphones. Very linear on my dynamic headphones and nothing to write home about. I have a few tube amps that can do amazing things with dynamic headphones. This thing has made my Fostex, Hifiman, MrSpeakers and my Audeze headphones sound alive in a most unusual way. It's like this amp has brought a new dimension to the sound of all these headphones. With this amp I just enjoy a new life on my old expensive planars. I do believe I will buy another!
