For me is worth the mony, he have that overall big sound i always follow, with big bass added . Set of the higher frequency is also good, they are current and they have quality, no necessary spikes on the higher midrange, breatheable space, with Qutest very nice hologarphy, imaging and countors. Fast little amplifier full of emotions. The bass is intresting. Its very big with headphones but not kinda full, and that makes every headphones sound super clear and precise. Its also not just good but very orginial sounding peace. Ive read somewhere in some review, its perfect companion for Meze Emyriean. I think he is more suitable for high eficcent planars, but for dynamics he does job too. He controls the sound like sport car, with power and drive, its sound strong and smooth but never soft. For me does the job with my SE Master 1 and even better with Final D8000. id like hear him with HEDDphone, TA Solitaire or some ZMF hp.
