AKR-03
I was lucky enough to get to audition this for an hour or so, even though i can only try them for a short amount of time (i am trying not to get the infamous 'poison') the sound it produces was sublime, i had never heard an iem that can produce such deep hitting bass, with very sweet lush mid and excellent high (i heard a little roll-of when its at high, but maybe its just my feeling, considering i only got to listen to them for a very short period of time)
AK120 + Kojo-KM 01
When i tried to my AK 120 + KM-01, single-ended, it was good, not as excellent as one may have hoped. The mid is very lush and apparent (Kojo's doing i think), but it sounded quite damp and not as open as i liked. The low was decent, it has enough punch to make my head moved and my heart throbbed a bit. The high was a bit rolled-off, i need to audition it for one good night before making further comment.
Ipod + Clas-db + Hugo
Now, this is where the AKR03 truly shone. I mean, OH MY GOD, the Kojo was clearly not powerful enough to drive all 24 drivers from the AKR-03. Hugo showed me how AKR-03 should really sound like. Lemme give you a short tour on how i felt when i heard the combination when i played Quenn's We will rock you.
As soon as the songs started. my mouth was widening from ear to ear involuntarily. The very deep hitting, full, not exaggerated low-end was so incredible that my head started to rock by itself, my heart throbbed, my foot kept thumping the floor. The sound of the infamous boom-boom-clap was so incredibly recreated that I almost stopped breathing.
The mid was a bit recessed when i was playing Quenn's, but when i switched to Buble, Nat King Cole, Sinatra. The vocal truly shone, it was very intimate, lush. And for an iem, the headstage was incredibly large, even comparable to LCD-2. I need further listening to really know how it sounds like, i was too captivated by the low-end that i forgot everything else.
I was unable to say anything about the high since i hadn't got the time to fully listen to it. I can only say that it was extended and beautifully recreated.
I am trying to get a loaner program to give it a good-night listening to. The low alone was enough to make me open my wallet. But 1800 grand was a huge sum of money for an UIEM and i need further assurance.
