The AK4493 DAC and Digital Audio Remaster technologies provide true hi-fi sound previously exclusive to Astell & Kearn's digital audio players.At a Glance 3.5mm, 4.4mm dual outputAKM AK4493SDAR (Digital Audio Remaster)Supports iOS devicesInterchangeable cable (USB-C / Lightning cable included)Supported UAC1.0 (For gaming system)Roon testedUltrahigh Resolution To achieve the highest audio quality achievable with a USB DAC, the AK HC4 is the first in the USB DAC Cable lineup to incorporate AKM's DAC. AKM's DAC has earned much love when featured in Astell & Kern's digital audio players, but due to the small size of USB DAC Cables and the challenges of amp design, it has been difficult to implement in the USB DAC Cable lineup until now.The AK4493s DAC from AKM, used in the AK HC4, is further enhanced with improved noise control, lower power design, and ultraprecise amp design technology, delivering exceptionally high-quality hi-fi sound. Furthermore, it supports Native DSD256 and up to 32-bit / 384 kHz to handle any high-quality audio source, allowing you to experience the high-grade sound quality that Astell & Kern delivers.Precision DAC and Amp Design In order to gain stable output power and ultrahigh-quality hi-fi sound through the Dual Output, AK HC4 introduces an exclusive AMP circuitry that supersedes the standard built-in DAC AMP.Astell & Kern used microresistors and capacitor parts to achieve a small footprint without compromising performance. Carefully selected ultrasmall tantalum capacitors, which are used in AK player products to create a stable system and audio performance by controlling the power fluctuations, are also included to create an optimal audio circuit design. In addition, the output and audio performance are enhanced with Astell & Kern's unique power management technology to minimize current consumption in respect of the connected device.Dual Output The AK HC4 features Dual Output with both 3.5mm and 4.4mm connectors, allowing you to use AK HC4 with most hi-fi IEMs and headphones without the need for adapters or additional cables.The 4.4mm balanced output provides a high output of 3 Vrms, maximizing the performance of sensitive headphones and IEMs, while ensuring clear channel separation and minimal noise.The 3.5mm unbalanced output is compatible with the majority of existing IEMs and headphones, offering a sufficient output of 2 Vrms to fully experience the capabilities of your IEMs.Digital Audio Remaster Technology The AK HC4 is equipped with digital audio remaster (DAR) technology, which was only applicable to the latest digital audio players from Astell & Kern.DAR technology is developed to upsample the sample rate of the sound source being played to go beyond the limits of the source format. The high sample rate allows more refined play and offers delicate and analog-like original sound, helping you to enjoy the richness of the original sound, subtle differences in the nuance of the music, and rich sounds at a higher level.In addition, the DAR slide key on the side of the product gives you a more intuitive selection of DAR options.PCM44.1 kHz range PCM will be converted to 352.8 kHz for playback48 kHz range PCM will be converted to 384 kHz for playbackDSDDSD files below DSD256 will be upconverted to DSD256 for playbackHigh Compatibility and Support for UAC 1.0 and 2.0 Gaming While modern smartphones, tablets, and PCs support UAC 2.0 connections, many gaming devices still exclusively support UAC 1.0 connections.To cater to both scenarios, AK HC4 ensures compatibi
