FX-Audio DAC-X7 First look Specs Chipset : XMOS+CS8422+AK4490 + TPA6120 +OPA2604 Power Output : 120mW Sample Rate: USB - 32bit / 384 kHz Coaxial / Optical - 24bit / 192kHz DSD 64 / 128 / 256 Interface Input : Optical, PC-USB, Coaxial, Micro USB, AUX Interface Output : RCA, 6.35 (3.5 ) Headphone Impedence : 16-300Ω Operated : Button and Front Panel Volume Control Power Supply DC: 12V 1A Initial Impressions If you were thinking about spending under $200 on a DAC we now have a new contender with the AK4490 DAC chip, I believe this is the same DAC from the Schiit jotunheim & SMSL M9. I can testify that sound is a step up from any of the sub $100 DAC's I have tested. My initial impressions are the sound is very smooth, almost delivered to your ears on a velvet platter. Instrument separation is enhanced from cheaper DAC's and that is just on my Takstar 82's which normally sounded a little harsh are now less fatiguing. I am able to pick out sounds that I did not normally hear before. Build quality is again sturdy like the X-6 in an all metal construction, all the switches feel solid and the screen is a nice touch. The power button acts as an input selector with short presses and a long press when you want to shutdown, when you do so if connected to windows reverts to the last or default audio source which is very handy. The volume knob also acts as an mute button. The two usb's can input audio but I think only one at a time so you could possibly have your phone as an audio source, I'll test that in my full in my full review along with a MK2 T50RP Argon, M1060C and maybe a HD650 in the coming weeks..
