I just brought Objective 2 amp recently thanks to leolabs
Tried it with superlux HD668B and as expected it drives the HD668B really well! My impression after a few hours using it :_
- the clarity is much better to me then the one from maverick D1. The instrument sounds can be heard very clearly while not experiencing extreme sibilance during playback.
- the bass is still light which is not great for any bass oriented music ( trance,dubstep,etc ). Then again I'm not expecting anything much from HD668B when comes to bass anyway. This superlux model doesn't do well in bass department to begin with.
- the mids, soundstage doesn't change much when comparing the ones with O2 and without it.
Even through the price for the amp is higher then the headphone itself ( around Rm330 ) but I believe this pairing is greatly suitable for those who are into microdetails.
songs that I used for this impression :_
- Tempus Horizon by God Is An Astronaut || Album: Far From Refuge ||
- Iron by Woodkid || Album: Iron EP ||
- Genesis by Justice || Album: Cross ||
p.s : will post some pic later
