The interface is mostly similar to the HM-801. It’s one of the easiest and most intuitive user interface I’ve seen on chinese players. While not too fancy on graphics, I think what’s most important is that it lets me choose my songs quickly. I downloaded some songs into the player via the USB port, fast and flawless. It won’t take ALAC (no surprise there) but it will take FLAC and WAV files.
The display shows some information about the music inside. I noticed that the top part of the display shows “16Bit”. Okay, does that mean that this thing can play 24Bit files too? Most probably, so why don’t we test it out. Inputting some 24Bit files to the player… and yes it does play 24Bit files!
Probably the most exciting part of the unboxing process is to hear how it sounds. The bigger brother, the HM-801, was the only DAP that can directly drive the Sennheiser HD800 headphone with such an amazing fidelity. I’d really like to see how the HM-602 handles the HD800, because if it passes this test, then it probably can take any multi-driver IEMs I throw at it.
I started by playing the Buena Vista Social Club album. Top notch recording with an equally great music. Ah, this is where my excitement peaks. The HM-602 puts out top quality signal, direct from its headphone out to the Sennheiser HD800. The soundstage is warm, the ambiance is all there, the musicality, the body in the music, the refinement, the smoothness. IMPRESSIVE. It’s just as good as how I remembered the HM-801 driving the HD800 (the real test, of course, is when we pitch the HM-801 directly to the HM-602). The HM-602 sounded like a very mature DAC, far from a regular DAP sound.
Next to U2’s Joshua Tree. One of the better recorded mainstream album, and a rockin’ music content. The basics are still there, just as good as with the Buena Vista Social Club. Bass texture is very good, but it lacks a little punch, and I would’ve wished the punch had some weight as well. I think this may’ve been the are where the HM-801 was better, but I’m talking from memory here. Where the treble was totally fine on the Buena Vista Social Club, on this recording I’m hearing a little harsh, around 2-4kHz. But the HM-602 is not even 30 minutes out of the box, so I’ll give it some burn in and see how it is after a few days.
Lastly, the HM-602 works as an USB DAC as well. Although the DAC capability is limited to 16/48, the sound quality from it is still very amazing, and definitely worthy to be pitched against some favorite desktop DACs.
This is just too good to be true.. stay in tune for some A-B matches of the HM-602!
Fang wrote me an email explaining how my sample unit is fitted with an output capacitor. They have done some testing and concluded that the output capacitor is not necessary, hence I’ve manually removed it, and now the slightly harsh treble issue that I mentioned earlier when playing U2’s Joshua Tree is gone! Awesome.
Also, during this process I’ve found out that the HM-602 uses a Phillips TDA1543 chip, and by chance we were just discussing at the local forum how awesome the TDA1541 chip is.
