Hi,

I currently have a Schiit Magni 2 Uber, a Little Dot Mkiii and a Sound Blaster Omni (USB sound card). My Upgrade path so far has been from a budget USB gaming headset, then the Sound Blaster with various headphones and most recently the Little Dot and Magni.

While I'm finding the Little Dot and Magni to be a big improvement over the Sound Blaster (I can hear noise when using my RHA T20is and the sound just isn't as engaging/pleasant with the Sound Blaster with other headphones) these amps aren't particularly well suited to in ears (at least at the volume I listen at).

With the Little Dot I opted to avoid it with the RHAs simply due to the fact that they are 16 ohm and the recommended impedance range for the little dot is 32-600 ohms. With the Magni, if I have Windows volume at 100% I have very little control range on the volume pot.

I've also made an observation. For the first few degrees of the Magni's volume pot there is a channel imbalance, so I've lowered the volume in Windows to allow me to raise the volume on the pot high enough to ensure the imbalance is no longer an issue (it doesn't take much but I like to take it to about 9 o'clock for peace of mind). The observation I've made is that when I raise the volume on the pot and drop it in Windows, the bass seems to become less prominent. The T20i is quite bassy (perhaps a little too bassy for my tastes), so this is actually welcome. The sweet spot (for me) seems to be 60% volume in Windows and around 9 o'clock on the pot.

Here's my problem. I've yet to install a player that will output bit perfect audio via ASIO or WASAPI on this PC (bought recently and have been listening almost exclusively to Spotify) but I intend to output bit-perfect audio in future. I remember reading that it is best to output at 100% and control volume from your amp to avoid potential issues with compression when listening to bit perfect music (Does WASAPI/ASIO even have volume control?). With that in mind, I'm thinking of buying a new amp better suited to in ears.

At the moment my eye is on the Dragonfly Red due to the excellent reviews, the fact that it doesn't take a battery (I hate non user replaceable batteries for products that I intend to keep for a long time) and the fact that the volume control is digital so I shouldn't have to worry about channel imbalance at low levels. However, I normally sit/lay on my bed and listen to music and my PC is a little over 2 meters away. Is there any reason I shouldn't plug the Dragonfly into a USB extension? I'd obviously prefer to have the Dragonfly where I am so that I can adjust volume rather than run a headphone cable across to it and have it plugged directly into my PC. Alternatively, are there any desktop amps better suited to in ear use (low powered so that I have plenty of adjustment on the pot or digital volume control)?

I've heavily edited my original post as well as the thread title, so I've bumped this thread as it's basically a different post rather than bumping the same question again.

You can drop windows volume well into single digits before there is any audible dynamic range compression. This leads me to believe your experience with the bass response was likely just dependent on your mood, and now you just think you hear it. I'd just keep the windows volume low. And yep, all analog pots have some level of channel Imbalance unless it is a stepping resistor ladder.

Also, the Dragonfly red actually measures quite poorly. Audioquest is a disgusting company anyway so I never recommend their products even when one doesn't suck. But anyway...

Foobar 2000 offers Wasapi and Asio. You won't hear a difference since windows isn't stuck in the 90s. In any case, volume control will work in Foobar while using Wasapi or Asio.

I thought WASAPI and ASIO volume was fixed. I've read a little bit on the subject of lowering system volume and realise that any compression should be pretty negligible, so I'm happy to use it, I just didn't realise it was available (with WASAPI/ASIO).

With regards to the bass level, it did seem fairly distinct. I try to be as objective as possible when it comes to audio gear and I know there are people in this hobby that are susceptible to placebo. I don't believe it was to do with my mood, however it is possible that I didn't volume match properly and the perceived increase in bass was actually due to the music being very slightly louder. On the other hand, if there is in fact a technical reason why the bass would be proportionately greater at lower levels on the amp's volume pot, I don't know enough about the inner workings of amps and relationship between amp and headphones to offer any speculation as to why.

There is no physical volume control on the Dragonfly. You have to adjust volume at the source (PC or phone).

Not even their HDMI cable?

What I'm saying is that the Dragonfly itself has no knob or buttons for volume control. When you want to change the volume, you'll have to get up and do it on your PC. Look at the owner's manual: http://www.audioquest.com/wp-content/uploads/2016/04/DragonFly-Red-FlightManual-EN.pdf
OK, cool, so I guess that the Windows volume slider will instead operate the DragonFly's volume control rather than being dealt with by the Windows mixer (which is bypassed by ASIO and WASAPI, or at least I thought it was).

Did you try using low gain instead of high gain on the Magni 2 Uber?

I recommend this player and these plugins for bit-perfect output. (Which plugin you use depends on your DAC and personal choice.)

http://www.foobar2000.org/download
http://www.foobar2000.org/components/view/foo_out_asio
http://www.foobar2000.org/components/view/foo_out_wasapi
http://www.foobar2000.org/components/view/foo_out_ks
http://wiki.hydrogenaud.io/index.php?title=Foobar2000:How_to_install_a_component

And yes, if need be, you can control the volume in foobar2000 in addition to anything else.

Yep, even on it's low gain setting it's pretty pokey.

I had Music Bee on my last computer. Foobar2000 and JRiver were the two at the top of my list of programmes to try next. Thanks for the links :)
