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.

Truly Fantastic - If you have a golden ear or listen to music critically you are going to love this App. The improvement is real and the adjustments it allows to be made have a real perceiveable effect. I highly recommend it. A few caveats: 1. if you are listening to music streamed from Apple Music, it does nothing (it cannot, Apple has made sure of it). 2. if your stored music is in a lossy format (MP3, etc.) do not bother with this, you cannot get the full benefit as the “bits” just aren’t even there to begin with. 3. if you are listening through the speakers in your laptop… not gonna hear a differnce. 4. if you are sending signal wirelessly to your stereo over over AirTunes, the signal is forced to 16/44.1 as that is the limitation of an Airport Express. Sound quality is a little better, but you don’t get full benefit. The only problems I have had with this App is from interference from native OS X problems. Listening from quality inear headphones (Ultimate Ears SuperFi 5Pro) I was surprised how good the headphone jack on the MacBook Pro could sound. Sending a signal via optical to my headphone DAC/Amp it gets even sweeter! Sending it to my 2-channel rig’s DAC the sound is quite smooth with no grain and added soundstage depth. Great work!
BitPerfect works great if you have a great stereo! - I find Bitperfect to be a very effective product! It makes my iTunes sound like a really high end CD player. I would describe the improved sound as: the digital audio file being “restored”, so that the soundstage becomes fuller and the music sounds “rounder”, more dynamic, more full of tone and timing. It reduces the harsh “digital” quality and presents the music mush closer to the ideal, original, pleasant sounding analog recording. That said, it is designed for Audiophile use, and if you don’t have really good speakers and a good external DAC, you probably won’t hear any difference in the details. It is impossible to do a live “AB” compare of iTunes to iTunes with Bitperfect running. But I did ”AB” “Normal” iTunes against a really clean record, and then iTunes/Bitperfect against the same record. The difference was very obvious, Bitperfect makes the music noticeably more dynamic, focused, transparent and overall pleasant. The best $9.99 you can spend on improving an iTunes based HiFi System. My signal chain: used 2009 MacMini (stock) – iTunes (all 16/44.1 CDs processed with apple lossless) – Bitperfect – an old USB cable – 2016 Schiit Modi2 Multibit DAC- 1992 Macintosh mx132 PreAmp – 1992 Mcintosh 7150 Power Amp – 2016 ELAC unifi F5 speakers. And It’s all set up in a critical listening arrangement.
A bit sketchy - When it is working, it is great, but about 50% of the time it seems to have trouble consistently generating an output signal. Or perhaps it's having trouble getting a signal. Anyway, I've given up using it as it's too much trouble trying to persuade it to work
Use external (hardware) EQ - I've not encountered the concern regarding software equalization, by including two "dvx Audio" 131s 31-band 1/3 octave hardware equalizers (one per channel) right after the nuForce uDAC (Digital to Analog Converter that I've ben using with the Audirvana App) and before the external amplifier. BitPerfect sounds, well .. perfect !
Native DSD Playback = Music Heaven!! - The feature this allows (along with the more expensive DSD master) that I wanted was native DSD playback. Not only does this allow you to listen to GLORIOUS DSD native sound using your DAC, but it also allows you to play the same files in iTunes, either as native DSD via your DAC or as high quality PCM files if for some reason you don’t have your DAC connected. You have not heard J.S. Bach’s Moll Messe until you’ve heard it in DSD!! The Kyrie is exquisite. It feels like I am sitting in the concert hall. Break through the KHz barrier, and head into MEGAhertz-land!! Your ears will love you! I am VERY impressed by this software. It recognized my DAC, and fired up the correct DSD signal on the first try. I couldn’t be happier. Next up: Warren G’s Regulate. I am in music heaven thanks to BitPerfect!! Thank you devs, PLEASE keep up the wonderful work on this great product. For reference, I am using the SABRE SPACE PLUS Audiophile DAC, which supports native DSD playback. I can confirm at the time of this writing that it works well with BitPerfect AND DSD Master, supporting both DSD64 and DSD128.
