맥미니에 어울리는 비동기 방식 DAC 을 써칭하다가 보니 외국 사용자들이 이제품을 많이 언급하더군요

그래서 아마존에 찾아보니 대충 이렇습니다.
사용자 평가도 상당히 괜찮고 , 리뷰대로라면 가격대비 매우 좋아 보입니다.

여러분들이 보시기에는 어떠신지요?





The HRT Streamer II is not just another USB DAC. The following two attributes set the HRT Streamer II apart from the rest USB DACs except a few costing many times more.

1. The HRT Streamer II is based on the asynchronous USB mode.
2. The HRT Streamer II supports the 24-bit/96 KHz high resolution input natively using the OS USB driver.

The asynchronous USB mode frees the USB DAC from being the slave of the USB bus which helps to reduce the jitter. Most USB DACs are implemented in the adaptive mode which is a pretty hostile arrangement that is prone to jitter.

Until recently, the asynchronous USB DACs are rare and sold at much higher prices. Just google "async USB DAC" and see what I mean. The async USB DACs give a brand new life to the USB based DACs. Suddenly, the S/PDIF interface is no longer superior to the USB in getting the quality sound.
