The new Akiba is all about presenting the best of the Taniso Mirai. They have always made nicely capable monitors but the Akiba now incorporates one of the best articulare treble I have heard from any of their monitors. One of the best mids of any of their monitors and for BA bass the tops for bass as well. If you measure a flagship IEMs based on the best of the best of what the manufacturer can do, then the Akiba here is a success. I would have liked to have just a few DBs less mid to upper treble presence adding that to the lower mids but otherwise I get this particular signature and its tuning. It is going for a reference level of detail and is very good at it.
