Buy one. Listen to it. Sounds terrific. Can it compete with Dragonfly Black? You bet. Blue or Red? Don't know, don't care. I paid $50 for this gizmo and it rocks. These people from Periodic Audio work hard and bring us affordable, dynamic products. Support them! I have two sets of their IEM's and now this Rhodium. A simple, effective, affordable, portable rig. Peace out!
