If your source (PC/Laptop/Soundcard) has optical/spdif output, Yes you can control volume in Windows. Good luck :)

If you really want to adjust the volume from Windows instead of physical volume knob. Despite being digital stepping, the workaround is using an optical cable instead of USB. (you'll need to buy your own optical/spdif cable)

Well, I believe many people only use the physical volume control knob on their amp. You want to set Windows volume at 100% because it is digital stepping. Meaning it reduce the bit depth correspondingly when you reduce the volume slider. Therefore, ideally, it's recommended to keep windows...

1. It is normal that you can't control volume with windows. It's designed to be like that. 2. The rear RCA output is a fixed line-out. I do not recommend plugging any headphone directly to it regardless of impedance.

I do hear static noise when touching the red and white cable together. But that's all I heard. I then connected my X6 line outs with Little Dot MK3 tube amp ON/OFF and didn't notice any issue on the X6 headphone out. I don't have any receiver to test on unfortunately... Although I'm not very...

Can you name a few songs or movie trailers that clips? I will let you know if my unit has the same issue.

What dac do you have in your wish list?

I am having the same question here. I bought LME49860NA and OPA2604, while lme49860na works great, but I do feel opa2604 needing a bit more juice.     Yes they work simultaneously, and the volume pot only controls headphone out.

In my opinion, you really shouldn't pair a 38ohm M50x with OTL tube amp. Suggestion from me: A) Pair your headphone with solid state amp (or hybrid tube amp) if you do like the sound signature of M50x B) Acquire higher impedance headphone. If you like bass and closed back, DT770Pro 250ohm...

I hate to bring back such an old thread.   But is there any similar device that'd do the same job? The closet might be a Schiit Sys, but it require a lots of adapters switching between RCA and 6.35mm plug

Oh actually that's even better for my taste. So I don't need to worry about how to properly tune the dac volume when paired with additional amp. For some reason I always thought the RCA output on the back of DAC-X6 is pre-amp. Obviously, I haven't try it out just yet because I'm waiting for my...

Are you saying the RCA output on the back is a line out? meaning the volume knob on the front panel will not have effect?

thanks for the examples!! and you don't have to pull if out if you're not using it.

Did they say it might be faulty because of the volume being too loud? The shipping cost more than $30 to China from USA. So I guess contacting Massdrop is my only choice.   Btw, how far do you dial the volume knob for your headphone? just curios

Thanks a lot. Appreciated

When I turn it all the way counter clockwise, it's dead silent. Then, if I turn it up by 1 click, it's channel imbalanced where right channel has lower volume. (should be normal on an amp) Therefore, I assume the volume knob is placed correctly.   Anyone like to share how they dialed the...

T_T feeling like I should talk to Massdrop for RMA, but what exactly should I tell them? "I guess the amp is acting weird by being too loud"?? Wondering if there's anyone with DAC-X6 near by 94539 area that can let me cross check the unit...   I believe AD900X has 100 dB/mW sensitivity...

My unit has OPA2134PA   Btw, you've any idea what does the jumpers next to 1/4" jack do?

You have heard me correctly. And frankly I don't think this is how it should behave. Hence, I wonder if there's way to change its gain setting. My unit was bought from Massdrop back in mid October.   I was surprised when I hook it up with HD650 & DT990. I'm not saying it has the power to...

Just wondering if anyone knows about the 2 undocumented jumpers? I've tried flipping it around, but I can't hear much of a difference... kinda weird   And btw, does anyone know how to "Reduce the Gain" on this amp? I read somewhere in this tread that people are using it with high sensitivity...

How's it going? I'm Mipaw. I've been a long time reader of the forum since 2010 without an account because my favorite user name were taken :( Recently decided to create the account and am ready to start comment.
