Sometimes I've found that the audio drivers for UAE sometimes loop unnecessarily but if you run through the more processor consuming hardware sound emulation (in particular, not using AHI as an audio.device substitute), it should be better.
I run EUAE on my Intel Mac Mini and the HiToro GUI frontend. They work well together. Also, I've discovered that the AHI audio driver works as well under EUAE as WinUAE even though that isn't documented.
