Latest Audirvana Plus beta
Just in care you are unaware of the latest development of Audirvana Plus, the developer has implemented a significant feature in the upcoming release called Direct Mode. According to the developer: "Direct Mode shortens further the audio signal by bypassing all CoreAudio, even its lowest level HAL layer."
It also brings back the long missed Integer Mode support to OS/X Lion.
I have listened to it for a couple of hours and my first impression was astonishing transparency and micro dynamic.
The latest release is in beta so it isn't 100% bug free but I think the sound quality is worth the download.

BTW, I have no connection to the company whatsoever except being a happy user.
