MSI X99-GODLIKE Gaming Audio Boost 3 Pro Solution Has Some Serious Chops - [Techpowerup]

The past two generations of motherboards saw the onboard HD audio finally get a quality leap it deserved, as motherboard makers addressed the shortcomings of onboard audio in dealing with heavy gaming and audiophone headsets. We've seen things like a 115 dBA SNR CODEC by Realtek (ALC-1150), ground-layer isolation, de-pop circuits, audio-grade electrolytic capacitors, and headphones amps become essentials for today's high-end motherboard onboard audio solutions. It looks like MSI is trying to push that envelope even further with Audio Boost 3 Pro, a new onboard audio solution making its debut with the X99-GODLIKE Gaming, which could also featuring on some upcoming high-end LGA1151 motherboards by the company.

To begin with, the solution consists of two separate DACs. An ESS Sabre 124 dBA SNR chip handles the front-out and headphones out channels; while a Realtek ALC1150 (115 dBA SNR) handles other analog channels in a 7.1-channel setup. The way this works is that the Realtek chip is wired to the HDA channel of the PCH, while offloading select channel D/A conversion to the Sabre chip. Further downstream to this chip is a 600Ω headphones amplifier chip by TI. Even the other analog channels have amplifier circuits. Signal loss is prevented by Nichicon Muse electrolytic capacitors. The CODEC and DAC are capped by an inner EMI shield, and the boards outer metal shroud; and is isolated from the ground-layer of the rest of the board. This solution also features Nahimic, a sound quality enhancing DSP used in the defense and aerospace industries. All analog jacks feature gold-plating. Digital outputs include optical TOSLINK. Unrelated to the audio solution, the X99-GODLIKE also features a special USB port meant for headsets, that has additional electrical stabilizers.
