I own both the Clear OG and the HD800S and love both of them without EQ. If one of them would break, I would immediately try to buy a identical replacement. However, for both the Clear OG and the HD800S I only like specific DAC/amp pairings. For the HD800S I really enjoy the combination of Ares II with the SA-1, even though I sometimes would enjoy a little bit more power coming out of the SA-1. After playing around for quite a bit with the Clear OG my preference is a D90LE/THX887 stack without ever needing the power reserves the THX887 could provide.
These sensitivities to DAC/amp combinations are in stark contrast to the resilience of the Arya Stealth performance on a wide variety of DAC/amp combinations. I currently enjoy the Arya Stealth on the EF400, but also like them on many other configurations, even though I more often reach for the HD800S and the Focal Clear ...
P.S. I mainly listen to classical music
