Our take on the HiFiMAN™ Express HM-601 Slim

by Ralph Graves

The HiFiMAN HM-601 Slim is simply a portable music player. But it's no ordinary portable music player. The HM-601 is designed for the discerning listener who wants the convenience of on-the-go music without sacrificing sound quality and optimal headphone performance.

Remarkable sound quality full of warmth and presence

The HM-601 sports an advanced dual 16-bit DAC (digital-to-analog converter). This DAC ensures that your digital music files will be reproduced with rich, full sound. And unlike most portable devices, the HiFiMAN can play high-resolution audio file formats, such as FLAC, WAV, and Ogg Vorbis. So you don't have downconvert your uncompressed audio tracks just to get them to play on your portable.

Room to grow

High-resolution audio files take up a lot of memory — and the HM-601 is up to the challenge. In addition to having 8GB of built-in memory, the player also has an SD card slot. Take along as many 32GB SD cards as you want and never worry about filling up the player and limiting your playlist.

Listen with your best pair of headphones

It takes a pair of high-performance headphones to fully experience the rich, detailed sound the HiFiMAN's DAC delivers. That's why the HM-601 also features a built-in headphone amp. A typical player's headphone jack just doesn't provide enough power to properly drive demanding high-quality headphones. The HM-601#39;s powerful headphone amp ensures that your headphones have the juice they need to sound their best.

Simple navigation and display

The HM-601's navigation screen has a no-nonsense, stripped-down retro look. The screen only displays text — no video, no graphics, not even album art. But if you're just there for the music, the HM-601 provides the navigation you need. You can sort your music by album or artist, and organize your music into playlist folders.

You can also adjust the EQ settings, making minor (or major) adjustments as you choose. A selectable high or low gain switch lets you adjust the amp's output to match the sensitivity of your headphones. And the volume control is an analog dial so you can play your music exactly as loud or soft as you want. Now that's old school.

Overview: The HiFiMAN Express HM-601 Slim (8G) is a high-performance portable digital audio player. It features an internal 8GB flash memory, and has a slot for SD cards up to 32GB. The HM-601 has a high-quality DAC to give you excellent sound quality. Coupled with the player's line output, the HM-601 can double as a portable external USB DAC for your home computer or laptop.

TDA-1543: The HM-601 uses the non-oversampling Philips TDA-1543 digital-to-analog converter (DAC). It is capable of playing multiple formats of compressed music (MP3, WMA, AAC, Ogg, FLAC), as well as hi-res 96/24 FLAC files.

Headphone Amplifier: The built-in high quality headphone amplifier can easily drive efficient in-ear monitors and full-sized dynamic headphones. A Hi/Lo Gain switch on the side lets you pick the setting that sounds best with the headphones you're using.

Inputs/Outputs: The HM-601 features a USB Data Exchange input (Mini-B Ver.2.0) for downloading digital music from your computer. You can simply drag and drop your music files to transfer them to the player. There are two 3.5mm outputs on the top panel: one for headphones and the other a line output.

Power: The HM-601 is powered by a built-in rechargeable battery. The battery can be charged via USB or with the supplied AC adapter. A fully charged battery provides 9 to 10 hours of playback time.

Note: The AC adapter is equipped a European two-prong plug, and comes with a US power adapter. It is compatible with 100-240 volts.

Crutchfield Customer Review (What's this?)
I wanted something to listen to while watching sports on TV or late at night. Right from the get go I was blown away with the sound. Very easy to hook up, just drag and drop music file. It will take some time setting up the menus... Save yourself a lot of time and set up music folders on your PC by artist before you copy to HiFi as you cannot save a song list in a group of files it will not sort right. use one folder on PC place all you albums in that folder before the transfer also the directions from HiFiMan suck big time my advice is just play with you will really enjoy it. Also buy a set of Monster buds from Crutchfield it will sound better than most home stereo receivers.
The sound is incredible you will hear sounds you never heard before...
Directions are terrible ........
