Well, it's a 3.5 jack in both sides. Is that a Stereo cable? :-)
Note that unless you're using an external amp you need to test with your headphones connected to get a reasonable idea how good the devices are driving a real load.
How is it possible to test it with headphones connected?
So, here's the results when I add a Splitter to the out jack - one leg connected to the Line in and the other to the headphones.No splitter: Splitter + HeadphonesSeems like the results over the Headphones output has improved with the splitter...
Seems like the results over the Headphones output has improved with the splitter...
So lets some it up:Are the results supporting the use of a specific card or slot (Headphones vs Earphones jack)?If not, I should probably stick with the USB Card, as it's easier to 'switch' between.
Your onboard card with speaker out gives better quality than the headphones out or the USB card.The difference is probably audible, but certainly not easily.
I'm slightly surprised the results for the higher impedance headphones (HD650 at 300Ohm) are better than those for the 120 Ohm model (AKG K601).
Brand,Yes - I hardly believe I'll be listen to Music with max volume (I could hear the RMAA tests clearly when the headphones were on the table).
Below you can find the results with 'Optimal' volume. On the Speakers output the Max was optimal. In the Headphones out and the USB Card I tweaked it down a bit.It seems like the USB Card is performing much better with volume at 2/3 than max:
Still, I'm assuming the Headphones Onboard port is still performing best?
What I meant by being 'Safe', is that some Audio will require me to play around with the Volume, this 'limitation' will make it unpossible to reach the unstable state. Right?That in case that indeed there is no real benefit in using either the usb or headphones audio and quality wise.
