En computex 2015 fueron presentadas 2 nuevas tarjetas de sonido, que la verdad me parece muy buenas opciones.
La primera es Power Color.
Featuring a C-Media CMI8888 native-PCIe processor and a Wolfson WM8741 primary DAC, this card continues with a 124 dBA SNR for your headphones and front-out channels, coupled with a TI LM4562 OPAMP swappable amplifier.
Also boasting 600Ω impedance headphone support, this product further supports stereo RCA out and 7.1-channel optical SPDIF output ports, drawing all of its power from a single 4-pin Molex plug.
If you're after alternative connection options, there is also a 6.3mm headphone jack and an included 'daughterboard' that provides additional analog channels and 3.5mm jacks.

ASUS unveiled two new high-end 7.1-channel sound cards under its premium STRIX brand, the STRIX RAID DLX, the STRIX RAID Pro, and the STRIX Soar. The three are based on a common base card design, and differ with features and DSPs. The DAC component of the card consists of a native-PCIe multi-CODEC HD audio controller, wired to an ESS SABRE 9006a DAC, dedicated to the front audio output, with 116 dBA SNR; and a separate 110 dBA SNR DAC wired to the main headphones amplifier. On the RAID DLX, the front-out DAC is a higher quality SABRE 9016a.
The main amp can handle 600Ω impedance headphones. On the software side of things, is a Raid mode (positional audio), Sonic Radar (lets you pinpoint enemies based on audio, and a new Sonic Studio control panel interface. The RAID DLX and RAID Pro come with an external module with audio jacks, and physical switches to audio feature controls, besides volume control.
