MASS-Kobo Model 475

First class service from Elise Audio. The item arrived promptly and in superb condition. Meet them at CanJam2025 where they introduced this amp. And it is a perfect pairing with my DAP and IEM. Recommend them to anyone looking for high end hifi help

Fantastic amplifier. If you have both iem and over ear headphones, andyou're trying to find an amplifier for them, then this is the one you should get. I pair it with fiio q7 and it really scales up the sound, both iems and over ear headphones. In low gain, it has a very clean sound, so you won't hear any tiny background noise even with the most sensitive iem. When turned to high gain, it can drive over ear headphones very well. Overall, it's a fantastic and well made portable amplifier.
