ASUS readies its upcoming Xonar D2 and Xonar D2K PCI and PCIe x1 sound cards

ASUS last week at CeBIT demonstrated its upcoming Xonar-series sound cards. The upcoming Xonar-series spawns two variants, the D2 and D2K in PCI and PCIe x1 interfaces. Dolby Digital Live and DTS Connect multi-channel audio encoding technologies are available for digital multi-channel audio. The Xonar-series also features 7.1-channel analog outputs for those that prefer analog to digital.

Early reports claim the ASUS Xonar-series feature an Analog Devices audio DSP, however, ADI denies any involvement in the sound card.

“I checked with our sales team and there is not an ADI part in this unit,” said Sandra Perry, product line manager, SoundMAX, DSP Division.

ASUS also touts Dolby Pro Logic IIx, Dolby Virtual Speaker and Dolby Virtual Headphone technologies for multi-channel upconverting and surround sound with stereo speakers and headphones. ASUS rates the Xonar-series with an 118dB playback and 115dB recording signal-to-noise ratios. The upcoming Xonar-series sound cards support 24-bit/192 KHz playback and recording resolutions and ASIO 2.0 as well.

ASUS internal testing reveals the Xonar-series is capable of low total harmonic distortion rates. The Xonar-series has 0.000006% THD on all eight analog outputs and the single line input, between the frequencies of 20Hz to 20 kHz. ASUS also equips the Xonar-series with an EMI shield and touts it provides “stable audio quality.”

EMI Shield ... thank you.
PCIe ... about time.
No SoundMax parts ... smart (and people think Creative drivers are bad)
Supports lots of cool features...happiness!
RCA outputs ... good.
Gold plating ... excellent.

Now the only big questions left are, which audio chipset and do the drivers suck? Overall it looks very promising though. Hopefully it will start enough competition to get Creative off their duffs and fix their drivers at long last.

Judging by the specifications and features, I'd say its the CMEDIA Oxygen HD used by the Auzentech X-Meridian and other DDL and DTS Connect capable sound cards.

Yep, I'd guess that too, but as I found out all the useful features of the CMI8788, like the DTS encoding and such are actually implemented in the driver, not the hardware. This rules out any useful Linux support, infact on the C-Media website it says:

Linux driver available (w/o Dolby®/DTS® and other DSP technologies)
