Alright, I need some help.
I have a Titanium HD and I recently purchased the AKG K702. I am trying to run the following setup: Titanium HD > RCA Line Out > FiiO E09K RCA (Aux) Line In > K702. The Titanium HD sits above my video cards and i have no other free slots to plug it into without removing one card, but can certainly test that out.
If I try to turn computer volume (and by association soundcard volume) to 100% and control via volume knob on the FiiO, I get bass distortion. Plugging the K702 straight into the headphone jack of the card removes the distortion but if I set volume to 100% there is distortion again. Turning the computer volume to 75% and still regulating with the FiiO volume pot removes distortion, regardless of volume on the pot (I've had it past 12 o'clock and normal listening is 9-10). I bet there is still some distortion at 3 o'clock or higher, but i'm not about to find out.
I read something about using RCA out from the card uses extra op amps, versus the ones used from the headphone jack, but I don't recall off hand which ones and what effect they have.
EQ is off. Bass Boost is off.
Could it be the headphones at this point?
Thoughts?
I'm more used to Planar headphones so I don't really understand distortion based on volume, ha. At work I have the T50RP with USB Modi and having the volume on the work laptop at 100% and regulating with the Magni volume pot causes no distortion. This is why I initially set it up at 100% computer volume. I guess I can test by both bringing these headphones to work and the T50RP home if that would help paint a better picture.
PS: I don't dare try the PC360 at those volumes as it is much more easily driven and either would blow my ears or the headphones out.
PPS: Just trying to find out if I should look into an exchange on the headphones, or if I need to get my soundcard looked at OR perhaps roll op amps?
EDIT: Tried singen and there was no distortion in the bass. I guess it could just be the track. My PC360 doesn't have this distortion when trying to listen to that same track (The Grid from Daft Punk's TRON: Legacy Soundtrack).
