My current setup is that I use the Radsone Earstudio ES100 with my Shure SE846 and a Balanced 2.5mm cable. I like this setup but sometimes do get annoyed by being tied to a cable and small device (ES100). Would it be a major downgrade to get the RMCE-BT2's? It seems that there is no built in DAC and only an amp, but the ES100's have both. Also, I guess I would lose the global EQ that you would get with the ES100's as well. Anyone with the RMCE-BT2 could maybe give some experiences with it? Would not even think about the BT1's given they only support SBC. Thanks in advance.
