Geek Perfect is a high-quality music player for 64-bit Intel Macs running OSX 10.7 or later. It integrates perfectly with iTunes, so you can use an interface you know, but get the sound quality that iTunes has never been able to deliver.
GeekPerfect is produced by BitPerfect Sound Inc, exclusively for LH Labs. It supports native playback of DSD files. Unfortunately, as with FLAC files, a major obstacle is that you cannot import native DSD files into iTunes. To resolve this problem, GeekPerfect creates “Hybrid-DSD” files, which can be imported into iTunes. But with these Hybrid-DSD files, iTunes will play DSD music beautifully through GeekPerfect.
