No, the DAC section is always active.

Thanks project86,


So, basically, if I plug in my headphone and have a pair of active speakers connected through the line out, I will get sound coming from both of them? If so, then I will need to turn off the speakers everytime I use headphones, which is a bit annoying.

Pretty typical, though.  This thing is really a DAC that happens to have a headphone amp - that the RCA outs are always active is not much of a surprise, although using active monitors myself, I get your issue (I run the Yulong through my RSA Stealth preamp, though, before heading to my Dynaudio BM5A's).

Thanks for your comment


It seems to be a really nice dac and I would second this if it has a selectable mode or something to deactivate the dac line out.

This sounds like a very interesting unit. I'm curious as to how it would compare to my Channel Islands Audio VDA-1/VAC-1 DAC and PS combo. Would any of you happen to have insight or opinions on that?

So I left the D100 on for the past few days, processing a 96kHz signal from the USB input and playing at medium volume to some IEMs. I have another component sitting on top of the D100, also turned on for burn-in purposes. So far no errors or issues. With the 2 units both on, the cases are somewhat warm, but not hot.

 

The weather this week is more mild than last week. I'm going to assume that the very high ambient temperature is what was causing my problem. I still have no way of knowing if it was a problem with the D100 itself or with my Dell Mini. But at this point it's not something I'm worried about. If we get another round of really warm days I'll be sure to test it again.

look forward to your impression on the Matrix Cube and the comparison between these two.

What are the differences between the low and high headphone output? How high should the headphone impedance be to actually plug it into the high output?

In general it is 0-300 ohms for low impedance phones and 300-600 ohms for high impedance.

it is more of a personal taste, the designer said that the all full size cans could be plugged into either headphone output and he suggested to try both to find out which one you like better. He recommends to use the low headphone out with IEMs. project86 addressed this in his review as well.

I was reading the HDP thread and it seemed that Headphoneaddict was sending the HDP to Skylab. So maybe there will be a comparison coming out soon

I'm actually pretty backed up in terms of reviews right now, so while I may get to this, it will be several weeks at least.

I know it uses that OPA21xx(forgot the exact number) for the headphone output.  Does it use the same opamp for the RCA/Balanced outputs? If any at all.

The RCA and Balance Out are fixed line out. Then the single is unamped by anything, isn't it?
