Hey guys - have just wired up my custom front panel audio and hooked it up to the sound card on the SupremeFX that's with the ROG Impact.

Have to say I'm extremely impressed with the on-board amplifier for the headphone out! Since when did on-board audio get this good??
 
Hi there,

SupremeFX is something that we're always developing on our ROG boards, glad to hear you're impressed. I've included some information on the technology below:

1. Built-in SupremeFX IMPACT audio solution for the delivery of an unbelievable hearing experience with the humble HD Audio Device, featuring:
 SupremeFX Shielding Technology, consisting of the following key elements:
- PCB Shielding, where each part of SupremeFX IMPACT has been carefully arranged to avoid unnecessary reduction of audio quality due to crosstalk or electric coupling for the optimal audio quality.
- Stainless Steel Cover, where the core of SupremeFX IMPACT is covered up by a stainless steel cover that blocks all electromagnetic interference Generated from nearby components from affecting the functionality of the audio core, allowing the SupremeFX IMPACT to perform at its full capability.
- The SupremeFX IMPACT audio module is moved out of the motherboard, enabling more layout space, as well as effective prevention of ground noise coming from the motherboard for the delivery of the top notch quality audio solution to the tiny mini-ITX platform.
 ELNA® Premium Audio Capacitors are used to enable smoother change in capacitor charge and discharge for the delivery of a warmer and pleasant audio output.
 High Fidelity OPAMP are adopted to form two separate differential output design as opposed to the traditional single-ended design to reduce the interference coming from the surrounding such as power noise. This enables a noticeably cleaner output, as well as better resolution for more details in the audio content it plays back.
 Ti LM4562 Hi-Fi OPAMP is adopted at the front to high fidelity trigger headphone up to 600Ω, while delivering high resolution, excellent sound details as well as boosting the already heat-pumping effect fir extreme gaming reality.
 Music PnP is newly introduced to transform the front MIC-In port into the input of any external audio devices when the system has been turned off. Enabling a clean yet easy to assess sharing of audio systems in your living room.
 The inclusion of DTS™ Connect enables real-time audio encoding to allow multichannel digital audio output via the onboard S/PDIF port.

Is the differential output technology setup on the FP headphone out and the Front out on the backpanel?
 
Yeah interesting that I always thought the front panel caused interference and sound quality loss, I have always plugged them in directly into the sound-card for better quality.
 
I have my headphones plugged in to the front panel for the ROG Impact and the level of noise is crazy low considering it's onboard. I have both USB + optical DACs. The USB DAC still has noise from the 5V and the optical I can still hear some mains hum.

but which ones the least noise/hum ?
 
Wish I could justify the Impact but Haswell just isn't a big enough upgrade to justify the move over Ivy Bridge, and Broadwell isn't miles off.

I assume we can look forward to an ROG Broadwell board with very similar features?
 
I have a pc with an onboard sound connected to the front panel and every time I plug in my headphones and put them on I notice distinct hiss and EM interference

Least noticable noise/hum is the sound card on the impact. Although I have noticed that it can pick up coil whine from my 7990, but looking to rectify that by shielding the custom FP cable

Not with the onboard from the ROG Impact!
