Got myself 4k in the lounge at the weekend and had to upgrade my Yamaha rxv 673. Thos is now going spare so was thinking about witing it up to the pc.

Is there any benifit going from an asus phoebus when driving AKG 612pros? Will probably be supplied by hdmi from the gtx670s or should I just stick with the phoebus?
 
No reason to think there's anything better in it for headphone use.

TPA6120 output of Phoebus has reasonable 10 ohm output impedance, giving very good electric damping factor with K612.
(controlf of driver by signal)
While that Yamaha has typical for AVR headphone out "stolen" from speaker amplifier output through big series resistors.
In that case 560 ohm resistors according to manual.

And service manual (page 137) confirms that.

Which means electric damping factor being at "there ain't one" level

And while TPA6120, regardless of hype, isn't the greatest headphone amplifier in technical signal quality, speaker amplifiers are made for high output powers instead of any highest signal accuracy.
 
From a gaming point of view, there is no point just for headphone use; unless you have interference or software issues with sound cards.
 
No interferance at all was just thinking the yam as an external unit might have been better than the asus
