I use two kind of sources: iPod touch 7th and Computer running W8. To the iPod the CLAS -dB goes through an ALO 30-pins to USB mini A adapter (which needs the Lightning-30 pins adapter). The CLAS connects to the RxMk3 with an ALO mini-balanced to mini-balanced cable. I have got the SM64 wire near ALO (SXC24) with a mini-balanced connector. It is the same cable than the JH16 since the SM64 has the same connectors.
Connecting the CLAS to a computer needs the ASIO Cypherlabs drivers and an ALO USB A to USB mini B cable.
The balanced mode and the ALO cable changes the sonic from the SM64. Gives more deep which those IEMs lack with the stock cable (surprisingly bass becomes comparable to the Westone4R) but keeps all the high quality of trebbles.
Also amped with the combo my HE-500. Not enough power but good details at medium levels.
