Hi, I recently got a pair of UM2 and love them. so far I have only been using them through my iPhone 4 and MacBook Pro without any amp nor DAC. They are definitely a step-up from the Q-Jays, or at least they seem to sound better. I haven't been able to compare them because I lost my Q-Jays before getting the UM2's.
Anyways, these have an impedance of 27 ohms and was wondering if it would be wroth getting one of these amps. They have plenty of volume with my iPhone so thath's not what I am looking for. I would like to know if the CmoyBB would improve the quality using these earphones.
I did a search and did not find anybody who mentioned how the UM2's work with the CmoyBB so if you know of a thread, let me know.
