Astell & Kern AK jr Portable High Resolution Music Player [Template]

Message from Seller: This powerful little music player cost $500 new. It has approximately 15 hours of playtime on it. Though I've classified it as used it is in pristine condition and I will leave all the music I've put on it and let you decide if you want to keep it. All music high resolution as well as DSD.  I can't justify keeping it because I am not able to use it very much anymore. I've recently purchased and enjoying a high end full music system for my home. Which is what I listen to when I retreat to my music room. 

I have owned and listened to many portable Player/DAC systems and this is by far the best I've ever heard for the money in its category. I've priced it to sell at less than half of what I paid.  Please no low ball offers. If you want to pay by credit card please contact me. Thank you have a great day!

MQS sources are commonly saved as a lossless 24-bit WAV or FLAC files during record production at the time of the mastering source. The AK Jr also supports 2.8 MHz DSD64 playback by converting to PCM.

High-resolution audio to go

It's small enough to slip into your shirt pocket — yet it delivers all the detail and depth of your high-resolution digital audio files. That's the Astell & Kern AK Jr. You'll want to use this tiny-but-capable AK Jr with a great set of headphones to fully appreciate the quality of the sound.

The 3.1" touchscreen features simple, intuitive controls.

Uncompromising sound quality

The AK Jr uses a high-quality Wolfson digital-to-analog converter (DAC) capable of decoding sampling rates up to 24-bit/192kHz. You can play high-resolution downloads from sites like HDtracks[ on the AK Jr without any additional equipment or file conversion. Even with lossless files or compressed formats like MP3, the AK Jr can help your music sound its best. Its high signal-to-noise ratio and low distortion lets the subtle details of your music come through. Its high-fidelity, low-impedance output gives your headphones more power than most portable music players, for optimal performance.

Touchscreen and push-button controls

The player's 3.1-inch color touchscreen is simple to navigate. And it displays artist and title info as well as album artwork. And because this is a high-resolution audio player, the AK Jr features an analog volume knob, so you can make small, nuanced adjustments.
