Does the job, but no EQ

Because BitPerfect is playing your audio instead of iTunes, your equalizer settings are completely ignored. Just something to be aware of if you care. In my experience, messing with the EQ for 5 minutes makes a much bigger difference than a nice DAC or exactly matching the source and output bitrates.

It works as advertised (in my limited testing), though.

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.

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 !
