At matching volume level I found both O2/ODAC and M8 sounded similar on a blind test listening with T1. But with sensitive iems, M8 sounded a bit grainier background. Most likely because it has a higher noise floor than O2.
M8 is known to hiss with sensitive IEMs and their fix is to drop gain by 6 dB. That drive the background noise to below audible levels at low gain apparently. And it costs $100 to get them to do it.
