M2Tech HiFace - using it? Like it?

Indeed it's a cracker and sounds rather brilliant when used with Pure Music & iTunes on the MacPro, the most recent release below is 100% cooking on my rig !

Thanks Coolhand! I checked out the Pure Music website and if I am understanding it correctly this program stores the music and plays it back while the "administrative" tasks are left to iTunes. My question/concern would be this: My music is stored on an external HD rather than in the Mac. Pure Music would load up the Mac with all the music right? Second, is there any real noticeable sound enhancement with Pure Music vs. iTunes by itself.

Thanks for the reply.

I am using the Mac Mini with digital output to my PS Audio Digital Link III. I started using the optical output to the DLIII and it is good. Adding the M2 Tech Hiface converter, the sound became more detailed with a larger soundstage. I use 2 external hard drives to store the music. I am only using iTunes and have not yet tried the other programs such as Pure Music but can attest to the improvement with the Hiface. It may be an interim step considering that there will be an explosion of USB converters in the future. But, for the time being it is money well spent. It also allows the playback of high resolution downloads which the optical would not.

Thanks Tgrisham - glad to hear you are having success with the HiFace. I really am tempted to go ahead with it. Like you, my music is stored on an external HD (2 TB mirrored) so I am not clear on just how something like Pure Music would work but frankly, I am happy with iTunes and hate to mess with it. Appreciate the feedback.
