Exceptional Audio, Fine Support - I recently upgraded my Mac audio chain to include a new DAC (Digital Audio Converter.) My intent was to get the best audio possible from my Mac Mini playing through to my Yamaha Natural Sound receiver. In the process I downloaded and installed BitPerfect. It made a significant difference in the audio quality that I heard from iTunes. Just the increase in audio quality would have been sufficient to warrant a five star review for BitPerfect. However, along the way I needed support from this vendor. I must say that their support was response, informative and extremely helpful. This is a product that accomplishes what it sets out to do--specifically improve the audio quality coming from your Mac.

DON’T BUY - I’m sure this app is great in theory, but I bought it, installed it, and it doesn’t open at all. Wasted $10. Wait until others have successfully tested this on Mac OS X El Capitán.

Re-Writing my Review about DSD Files as it was DELETED - I am not sure how or why my previous review was deleted, but that’s pretty strange. Shortly after I changed it to two stars, it disappeared. So here’s my new and updated review: Bitperfect is great if you want to use iTunes to play back your DSD files over a DSD capable DAC. Unfortunately, it’s only 1/4 of the product. You also need to purchase the much more expensive DSD Master to achieve this. This also requires re-processing all your files to “hybrid-dad” files. The downside? Well, for me, many of the converted songs were not recognized by bitperfect as DSD. They would play back as PCM. I tried to get support for this, but after an initial answer and uploading some sample music files, I was never answered. Now bitperfect is also randomly crashing during playback. Not just for DSD files but for ALAC files as well. I finally gave up trying to use it. I updated my previous five star review to reflect these changes, and my review suddenly disappeared. I have since discovered Audirvana, and my search ended immediately. It handles my lossless files (all tyes) easily. It supports AU plugins (EQ, etc.), and many other features, and it also integrates directly with iTunes. I keep hoping there will be a bitperfect update that will fix stability issue for me, at which time I will update my rating again.
