To test whether it supports 24/192 file one Mac, you can try Audirava. This app can play 24/192 files.
I am pretty interested to.
In addition, I have several questions about this amp.
1. How long is the battery life?
2. Is it really enough for tough phones like HE-6? If it can drive HD 650 and HE-500 fully, I am already very thankful. I really want to know this.
Really appreciate it.
