I'm purchasing a Sennheiser HD598 soon to use on my computer.
But I'm unsure if I'll also be getting the Asus Xonar DG soundcard, namely because I own a Yamaha RX-V463 AV Receiver.
From some research I've found that the receiver has a Burr-Brown PCM-1680 DAC, is this a better DAC compared to the DAC in Xonar DG (Cirrus Logic CS4245)?
I want the best audio quality (I'll only use the HD598 for audio, so I don't use the 7.1 surround speakers ports etc.), will I get better sound quality on the Xonar DG (using the 3.5mm jack) or the Yamaha receiver (using hdmi or spdif)? Or are they equal? Because if they indeed are equal, I will purchase the soundcard.
If Yamaha is superior, is it better to connect the receiver and the computer with a optical spdif toslink cable (optical-out port on Asus P8P67 motherboard) or with HDMI cable (hdmi port on gpu: HD6870) or purchase the Xonar DG and use its optical out?
*I'm not planning to purchase an external amp with the Xonar DG, so just Xonar DG vs Yamaha RX-V463.
Thanks in advance.
Edit: If you have no experience with the receiver, how do you find the audio quality between soundcards and receivers in general?
