BitPerfect for Mac

Hasn't been updated in a year, and maybe that's the cause of its bugginess of late.

Didn't use to have so many problems.
But now it continually has conflicts with iTunes and the system volume. And tracks unexpecdly stop and another starts playing.

IMO it pretty-much sucks now, and I'm uninstalling it because I'm sick of the aggravation.

Regarding iTunes and "Bit Perfect." iTunes already plays back tracks perfectly. These "bit Perfect" apps are snake oil. See for yourself: https://www.evernote.com/shard/s25/sh/3d5d72ee-4b3a-406b-b5ff-b87e8b8433ed/5e98b67e3e9e35ac13277b3e8a415f90

Is this a joke? For Audiofile level recordings you need analog standard (not cassette) tape or vinyl. Anything else is compressed and sampled, unless it is stated to be audiophile quality on the source-i.e. lossless audio format from the source., which is not anything on iTunes or MP3. If you are over 50 forget audiophile due to hearing age degradation-i.e you can't hear it anyway. Any other claims for recording or equipment is marketing hype. Finally you have to own speakers or headphones that are capable of audiophile playback ranges with minimal distortion. If you don't have that, nothing else matters as that is what your ears actually hear. If you really want audiophile and can hear it, that is where your money should go first. mediocre headphones or speakers on the end of high end amps and players will not reproduce audiophile quality sound. It simply is not possible. In other words, forget audiophile, unless you are young, still have good hearing, and have a lot of expendable cash lying around for top equipment starting with output devices and following back to the source. Other than that, it is not audiophile, so stop wasting your money on something that cannot be.

Outstanding in almost every way. It gives you almost all of the advantages of iTunes (since it runs as a parasite on the iTunes interface), but enables you to avoid some of the limitations inherent to iTunes. What does this give you that iTunes does not? 1. Automatic bit-perfect playback. If your iTunes library contains tracks that have various sampling frequencies (normal CDs and most iTunes store tracks are 44.1 kHz sampled, "higher resolution" can be 48 kHz, 88.2 kHz, 96 kHz or even higher), iTunes will only be able to play one of these bit-perfectly, depending on the settings in Audio MIDI setup. Everything else will get resampled, unless you quit iTunes, change Audio MIDI setup to the new sample frequency manually, and then restart iTunes. You have to repeat the process each time you play a track with a different sampling frequency, or else your music will get re-sampled. This takes care of the problem automatically. If you are using Airplay exclusively, this isn't for you, since everything gets resampled to 44.1 kHz anyway (and if you use Apple TV, gets resampled a second time to 48 kHz). Those who will really benefit from this will generally have a collection including lossless higher-resolution files. If all you have are mp3 or AAC compressed audio, you aren't going to be able to hear any difference. 2. Memory playback. Some people believe pre-loading part or all of the track into the memory buffer improves playback. I'm not so convinced, but it doesn't hurt. 3. Playback of DSD audio files on a DSD-capable DAC. 4. Better upsampling and digital volume control (although you will always be messing with the bits doing that). The author wrote this software because he was annoyed that some other companies were charing hundreds and in some cases thousands of dollars for this same functionality.

Cant honestly see much difference other than it prevents multi speakers working over wifi? My music predominately stored at 256kbps AAC and played on the iMac with Harman Kardon SoundSticks III 2.1 Channel Sound System. I regularly patch it through to the Living room via an Airport extreme Wi-Fi and a cheap £40 DAC into Naim Audio Nait 3 amp to my Polk Audio R8 speakers. Can anyone give advice or recommend a DAC?
