Windows/Main (100%) -> NU Audio Card -> (DAC) -> NU Audio Card Headphone Amp (Control Volume Here) -> Headphone Out -> Headphones.

For simplicity's sake, assume I'm referring to an integrated amp here, and we'll leave the pre-amp/amp discussion for another day: Everything that comes before (in this case, just Windows/Main volume) should be set to 100% (or very close to 100% some opinions vary, so just stating that for the record). Generally, the last volume control in your signal chain should be what you use to increase/decrease the volume. Because of these interactions, it's possible that the final outcome may result in a signal that does not actually match the source audio (although we're really only talking about a slight difference). This can also have the added side-effect of adding more noise to the source because the amp is now working harder to bring the signal level back up to the original level.

When using the Headphone amp, you're adding power to the headphones to drive the signal properly, but if Windows/Main volume is lower, then you're amping an artificially quieter signal and giving more power than the headphone actually needs.

Therefore, lowering the volume is simply making the original signal quieter, which may or may not reduce the dynamic range of the source, and will occur before the DAC processes the audio.

When the main volume is at 100%, that's the default volume level for the Software side before being passed to the audio card. For the record, however, from our engineers and Audio Note's engineers, when using the Headphone out it's recommended to actually set the Windows/Main volume to 100%, and then raise the Headphone volume slider from 0% until the audio level is sufficient for your headphones. Most importantly, you should always follow the result that gives you the best performance and experience. do you think that by pushing more from the card it will make better sound? I like good audio but this matter is a bit empty space for me at this stage.

Thanks for your reply, never thought of the headphone impedance would make a difference. Ultimately I'd recommend that your first purchase be a set of higher impedance headphones (50 ohm minimum) before considering a $200 soundcard so that you can actually utilize the available amplifier power and receive the benefit of the high SNR.ĬhaobSiroc cmaranhao I have beyerdynamic custom one pro, do you think this audio card is a good match? I am using the one from my motherboard which is not that bad but sure both are very different. Motherboard audio is usually realtek or a rebrand of realtek's chips and those are all incapable of driving high impedance headphones well (I've tried to make it work) however your headphones only require 16 ohms which is something that realtek chips and even cell phones can drive just fine. I personally run Sennheiser HD 700s and they match well enough out of the box with just a little bass EQ tweak. Well the Nu Audio card allows you to swap opamps to alternate options if you find the default doesn't pair well with your particular set of cans (tweaking the EQ is where you'd want to start though).
