For the audio enthusiasts at CES this year Calyx Audio (Korean maker of audiophile-grade audio components) has a new prototype to show along with last year's Calyx M music player, and for an audiophile product the pricing is very aggressive.

The PaT is a similar product in some ways as Calyx Audio's existing $199 USB DAC called the "Coffee", but this unit will be much smaller and will cost half as much at $99. And the reduction in price and size is only half of the story as the PaT also works with mobile devices as an outboard DAC/headphone amp. Apple iPhones and iPads will be supported, and Android devices with USB audio-out support as well (probably via USB OTG).
The PaT supports up to 16-bit, 48kHz files (AIF, M4A, PCM, OGG, and MP3) and will also control track playback and volume via hardware control buttons on the unit. The PaT requires no external power or battery, taking what little juice it needs directly from the connection to your mobile device. As for amplification, in typical Calyx fashion even this miniature board is using a discrete class A/B headphone amplifier. Since the PaT relies only on the power passed through the USB connection it is only capable of outputting 0.8 V, which by comparison is slightly lower than an iPhone 5 which outputs about 0.9 – 1.0 V.
The tiny prototype PaT in action
The PaT may be just a working board at this point, but the company has scheduled the release for February 2015, when the devices will be available in various colors of thin aluminum enclosures.
In the world of computer audio much more attention has been focused lately on advancements in sound, with special shielding and isolation on motherboards, special gold-plated USB ports for DACs, and customizable op-amps a trend. While the market for dedicated sound cards isn't what it once was, high-end PCI-E and USB cards from Creative (Sound Blaster) and ASUS (Xonar) are still widely available. Most of these products are for desktop users, but there is a growing number of portable devices that allow mobile users to experience great sound, too. For myself, great sound means faithful reproduction of 2-channel music, and it's nice to see attention paid to that area without the added effects of digital signal processing (DSP). Calyx seems interested only in engineering products that play back music as close to the source as possible, and I can't argue with that!
The Calyx PaT is scheduled to launch in February for $99, but like most high-end audio components it will take a little research to track it down. The USA distributor of the Calyx brand has a website with product and contact information here.
