Hi, I am new to head-fi, and am hoping to get some advice. So, i am testing my new portable set up: Rx Mk 3-B with new Solo dB., and iTouch. When using my Shure 535, it really sounded powerful. However, with the Beyer T1, i felt that the solo/mk3 combo was not driving the t1 that much (even at full volume and high gain.) It also didnt sound powerful when i connected the solo to my beyer HBC1 base and beyer dt880. I was testing with Rhapsody and aac converted files....
