Omni first impressions:
Using a Q701 out of familiarity (and cuz I know on some sound systems the treble can seem to have an edge).
The control panel is a little different than the SB Z and Recon3D USB, by default it was set for 5.1 surround instead of headphones, and interestingly the surround default setting was 40%. I turned the surround up to 65% (and left on crystalizer, turned down to like 15%, turned on Smart Dialogue to about 33%).
Oddly, my external volume control does nothing. It feels nice, with some soft detents and a feeling of momentum when you turn it, and you can click it, but it wasn't changing volume for me. No biggie, my keyboard has volume controls. Also, the red glow along the center ridge and around the volume is cool!
When I put on Borderlands 2, I was impressed, even with the Q701s plugged straight in. First, I was concerned because I heard an odd, regular clicking noise, but that went away about a minute after I got past the borderlands 2 menus. In-Game, the 1st thing I noticed was what a surreally believable (ironic, I know) soundstage of surround positioning the Omni (and SBX ProStudio) created. Even without stopping in front of a fire or something making constant sound and spinning around, I loaded with Ellie in front of me and talking, and it was instantly apparent that she was positioned in-front of me. Second, it felt like the volume clearly had a lot of headroom at listenable levels, I felt no need to reach for my E12 amp to double-up. I also didn't detect the raised treble harshness that the Q701 exhibits with some amps and DAPs... It was very clear and detailed, perhaps bright, but very controlled and I didn't get fatigued (didn't notice I had played for 5 hours straight, either).
I expect that my volume dial issue is due to driver wonkiness, but ladies and gentlemen... the Omni is at least equal sounding to the SB Z, without any compromises I could detect. Win!
