Not that we were necessarily asking for it, but we now have another spec to weigh up when choosing a new Haswell motherboard. ASRock's A-Style Z87 mobos will come with a bunch of audio-related features collectively called "A-Style: Purity Sound", which the company claims will result in a better signal-to-noise ratio (115dB) compared to regular onboard 7.1-channel circuitry. The boards will also come with a dedicated headphone amp that should be able to high-impedance drive cans up to 600 Ohms, plus DTS Connect for converting PC audio to the DTS codec for optical out. There's some extra shielding around the components, which lends plausibility to the better SNR and the promise of better sound quality -- so Purity Sound probably can't be dismissed as Purity Marketing. In any case, just make sure you also pay this much attention to your next power supply.
