I went with an X7 mostly for conveniece's sake. Since my PC and my consoles are close by, and are connected to the same screen, having two separate audio setups for PC and consoles seemed impractical.
Important stuff: X7 firmware update was released today.
Here are the patch notes:
What's New:
- Added support for the E-MU XM7 passive speakers
- Independent master volume setting for headphones and speaker
- Supports volume control of Optical Out in standalone mode
Fixes:
- Fixed USB audio playback issue on certain system
- Fixed noise issue when Bluetooth® is connected and not streaming
- Fixed soft audio output issue on internal mic
- Fixed audio switching issue between headphones and speaker
- Prevents speaker calibration from affecting headphones
