Why don't you build some consumer grade products with Hi-Fi elements? One of my friend asked me last year. He was right, we do have the ability to build consumer grade products, such as headphones, sound card, players, as cheap as those sold in walmart, and sound a lot better. So we registered HIFIMAN EXPRESS trademark, and designed several new products under this brand. HM-101 portable USB DAC is the first one. Several new products such as RE-242 iphone compatible IEM will coming soon. We will keep use HIFIMAN trademark for Hi-Fi market in the future.

Why we build HM-101 USB DAC
Most modern computers have on-board sound cards, which provide relatively lean and cold sound. People call it "digital sound". Sometimes on-board soundcard have bad signal to noise issue so that customer can hear noise from sound card headphone output. Hifiman express HM-101 is a very small USB sound card ( as small as a matchbox) with headphone amp output and line output. We use one of the best sound quality USB D/A convertor chip Burr-brown PCM2702 as the key component in HM-101. We designed the headphone amplifer with the famous headphone amplifier chip TDA1308, with about 50 to 70 mw headphone output. HM-101 USB DAC can be used on both Windows and Mac.
