The Must-Have Accessory for Audiophiles On-the-Go

The award winning Calyx Audio M is the perfect solution for the audiophile on-the-go. The M functions as both a high-resolution personal audio player and a digital-to-analog converter. The M features Calyx's proprietary user interface, the 2015 iF Design Award for Communication Apps and Software M:USE. This powerful, intuitive software makes the M an incredibly easy to use audio player. One of the many perks of the M is its ability to drive most headphones, anything from sensitive in-ear monitors to power hungry over-ears headphones with ease thanks to the nearly 0 output impedance. The analog output stage of the M is fully discreet, meaning that individual resistors and transistors are used in place of op-amps to better contribute to the fantastic sound of the M. The audio output also works great with a car stereo auxiliary input, giving you the ability to play high resolution audio in your car.

Award Winning M:USE...

The powerful award winning custom-designed software, M: USE, gives you the ability to browse and create playlists directly. This attractive, feature packed proprietary user interface allows you to easily browse through your music by artist, album and track title while the search function lets you quickly find what you're looking for. With a quick swipe of your finger you can create multiple playlists in the M's Jukebox. You can also easily rearrange your play queue with an easy drag-and-drop function. Your stored music is just a touch away!

For Audiophiles...

With the ability to store up to 448 GB of music through SD and Micro SD card slots and also function as a DAC, the M is a true all-in-one solution to audiophile-grade audio on-the-go. Calyx engineered the M with an internal ESS Labs chip for digital conversion and the built-in micro USB input allows it to be used as a standalone asynchronous DAC. The best part is that the M can play virtually any file type including DSD, 128DSD and more! Calyx is well known for exceptional sound quality and the M doesn't disappoint.

Sleek Design...

The sleek, lightweight M features an ultra responsive high definition 4.65" rugged Gorilla glass OLED touchscreen display along. The easy to use slide volume control gives you point volume control in 0.5dB increments. Clalyx designed the M with a durable aluminum body to ensure use for years to come. No matter what you're listening with, be it your favorite pair of headphones or your sound system at home you'll never want to listen to your music through anything else.

Really, the M is the best-sounding, best-performing, most interesting stock platform available to portable audiophiles, the world over.
