2014 seemed to be the year of the portable high-resolution music player. Pono was finally released, Astell&Kern released the magnificent AK240, and then came the M, from South Korean manufacturer Calyx Audio.
I was asked to compare the M with A&K’s AK240. No way. The AK240 has many functions absent from the M -- though each might be the best in its price category, the price difference is significant. At $999 USD, the Calyx M costs a lot less than the AK240 at $2499, and you get less: no Bluetooth or Wi-Fi, thus no wireless connection to music stored on your computer -- and no form-fitting protective case. But what you do get with the Calyx M is very good, and makes it a reasonably good value . . . once the bugs are worked out.
In the box
The Calyx M comes with a soft carrying pouch and two USB-to-USB Micro charging cables, one short, one long. Its gorgeous copper color is matched by the cables. There’s no quick-start guide -- you download the instruction manual.
At 5.25” x 2.75” x 0.5”, the Calyx M is large -- about the size of a new iPhone 6 or Samsung phone, but thicker. Its 7.7 ounces felt a bit heavy in my hand over long periods of use. The front is almost all screen -- a handsome, 4.65”, high-definition (1280x720) OLED display covered with Gorilla Glass. On a tiny strip below the screen is an “M.” The rear panel is all smooth metal, with Calyx’s engraved treble-clef logo and manufacturing information -- the fine print. Along the top edge are a 3.5mm jack, slots for SD and MicroSD cards, and an On/Off button. On the bottom is the USB Micro jack for charging.
