I recently got a pair of Sennheiser Momentum headphones. This is my first audiophile piece of equipment and I've been trying to educate myself on audio equipment over the last week. From what I understand, I do not necessarily need an amp to drive these headphones since their impedance is so low; however, having a proper sound-card will help in getting better sound quality (less noise, better response etc...). Because the headphone cord is too short to make it to the back of my computer I've been plugging it into my Logitech G110 keyboard. This is a USB keyboard so I assume that the DAC/Amp are built into the keyboard.
Would it be fair to assume that the quality of the DAC/Amp in the keyboard is garbage? Even worse than on-board sound? If so, I suppose I should pick up something like a Asus Xonar DX and an extension cable for the headphones; thoughts?
Thanks in advance.
