SBX is the G3/G6 faked 7.1 and I don't care for it. SXFI is another attempt by them and I also don't like it. Voices become metallic robots and everything sounds like you are in a massive cave.

All that stuff turned off and just receiving 7.1 signal seems to up clarity and seperation. Perhaps I'm just getting a less intrusive DSP that I find pleasing.

I agree about stereo music, or rather I'm not focused on music with this setup.

I will say the ie200 sounds better in games like Doom Eternal when a soundtrack kicks in vs the a4000.
