The Asus Xonar Phoebus is yet another atempt from Asus to make a gaming capable sound card, yet such card has lower specs and measurements than their current Essence ST/STX flagship products. The only good thing I see about the Xonar Phoebus is that it is actually a sound card rather than the laughable Recon3D series from Creative, unlike the X-Fi Titanium HD that outperforms every single sound card in existence when it comes to gaming audio, and is basically the best consumer sound card, just like the Essence ST/STX are, albeit with different signatures.
For all that, the Xonar Phoebus is fated to fail. Asus should continually improve over past products, even if it's about hardware available on the market for some time.
Only reason I wrote that was just to see how long it took you to reply.
