Waltl says that: “The Stereo and Surround mixes on this Hybrid SA-CD are completely new mixes derived from the original multi-track masters. To achieve the highest audio quality, the recordings have been mixed at Media Hyperium Studios on an API Vision console which has been specially designed for surround mixing and features a fully discrete signal path including discrete multi-channel panning. A DCS 954 analog to digital converter has been used to create the DSD files. To keep the integrity of the pure DSD quality, the mastering has been done completely in the DSD domain.”
