I would guess A is for using the amp and D is for using the rca outputs. Meaning as a DAC. The unlock thing is probably an indicator that there is a digital input fed into the unit

Power I can understand means "ON", and since there is no ON/OFF switch I assume this is always on. What does "UNLOCK" mean? Don't want to break my headphones with incorrect settings. Sorry for the extremely remedial question in advance... any help is appreciated.

donunus is basically right.

"D" means DAC mode. The DAC/AMP only outputs signal from the digital input, i.e. Coaxial and USB. The RCA ports and Phone port are all working
"A" means AMP mode. The DAC/AMP only outputs signal from the RCA line-in ports. Only the Phone port is working.

"Unlock" ON means the Coaxial signal is not locked. OFF means the Coaxial signal is locked and you should hear music coming out.

For your case, you connect the unit to your PC via USB and your headphone to the Phone port, you should switch to "USB" and "D".

you guys rock! thanks so much. this is my first AMP & pairing it with an Sennheiser HD 600. Chose to go this route over a ZERO. USB connectivity was a major factor in my decision.

My Sennheiser HD 600 came in today, and they sound wonderful on the laptop headphone jack (Fujitsu Lifebook laptop). I don't listen to my headphones at loud volumes, but my understanding is the amp will improve the sound at regular volumes.

i'll provide feedback once I get it all plugged in!

just changed in direction. I just decided cancel the order of this dac and got a valab instead

Looking forward to your feedback because I'm a user of HD600 and the MK2 DAC

Looking at its design and parts and layout it's a serious cut above the Zero, enough to compete with some pretty mainstream designs. At $150 shipped this is a no brainer, it's even cheaper than a lot of Zeroes, looks beautiful too not cheap.

Does anyone know if there is a Toslink version of the hifidiy mini USB Dac? I do see that their is a Muse version on ebay, but want to make sure I get the best sounding and most recent upgrades.

thanks

The MUSE version is just a copy of the original hifidiy mini usb dac. Don't know the Toslink version.
In China, hifidiy is making some diy kits for diyers like me. The very original mini usb dac is one of these kits. Also they sell finished product, such as the MK2 version. The "AUNE" is their official brand for finished products selling abroad.

I need some more time to write up my review; I need to listen to some music samples with and without this DAC. I also have a friend who has a pair of HD650 cans, and has the same DAC.

He was able to notice the change in quality immediately vs. when he was plugging his cans directly into the headphone jack of his mac.

I was not able to discern as quickly, if there was a change. This amp can drive my cans at much higher volume if I wanted; but I don't need that.

Again - I need to do some more thorough listening tests. Happy with everything so far!

Any updates on reviews about this?

How might it compare to the Fubar II, Gamma-1, and HRT Music Streamer (standard) or any other USB DAC's in this price range?

Anybody? Is this worth getting at $150 to be my 1st DAC?

It is worth. 100% worth it. I'm in burn-in stage and waiting for opamps for rolling. Just want get at list 600 hr. before post any thoughts.
In few words it really good AMP/DAC. And few headfiers have mentioned that with some more tubee sounding opamps it's shine like hi-end stuff. It's have very deep, wide spreading bass, a bit dark mids and kinda metallic highs out of the box. But with burn-in it gets better a lot. Now, after around 400 hours it really great. I just love this bass and transparent sound what I'm hearing now, writing this words!

How is the soundstage and depth of this? I am primarily looking for something in this range to open up the sound I currently and getting. I also like a slightly warmer signature. Thanks!

I can assure that the metallic high is totally 100% true. Let's see how it changes with time, mine has been used for 1-2 hours now.

Definitely update as it breaks in. Thanks.
