Wow if true; even the STX *only* has a 120 SnR on its primary output, so 127db SnR is simply blowing everything else out of the water. Even 120db SnR on the surround outputs is exquisite. At first glance, looks like an upscaled Xonar Xense.

The primary DAC for headphone/front-out channel of the ROG Phoebus is TI-BB PCM1792A, with stellar signal-noise ratio (SNR) of 127 dBA. Other main channels are handled by Cirrus Logic, probably the CS5381, with SNR of 120 dBA. There's also a tertiary Realtek ALC889 (110 dBA) CODEC that probably handles an independent set of audio channels, or handles the digital outputs, since it's licensed with a few Dolby technologies. On the AMP side, we spy bleeding-edge OPAMPs, a Texas Instruments 6120A2(?) AMP chip (for the headphones channel), etc.
