As someone who was dealing with quite a bit of background hiss and left earbud radio interference when using very low impedance IEMs, I ordered and just received an iFi IEMatch and used my Campfire Audio Holocenes with the A306 (IEMatch set to high and single ended). All static and noise completely eliminated. You do lose a chunk of volume as the high setting adds 12ohms of impedance to your IEMs (takes my Holocenes from 4.5 to 16.5ohms) but I have not had to max out the volume to listen at normal levels - i'm running the A306 at about 90% volume with the IEMatch and that is as loud as I require. A working solution if you have super sensitive IEMs. Will be keeping the A306 now. FYI for anyone interested.
