From there, I'd buy every tweak (if I bothered with them at all) with a liberal return policy, listen to every one of them blind, and send back everything that didn't earn its keep.
#PURE MUSIC MAC MAC#
I would load some of my favorite files into the hard drive of that Mac Mini, connect it via optical to a DAC known to have good optical indistinguishable from its other options (Benchmark is one) and then blind A/B to see what I hear compared to my CD transport. If I were just starting out in computer-as-source, I wouldn't immediately leap into that expensive and dubious fire. I'm not saying people aren't hearing differences, but I do question what it is they are hearing. If you have eliminated the possibility of electrical noise traveling from computer to DAC, and your DAC is designed to sufficiently reduce jitter below audibility at normal listening levels (and this is common in inexpensive DACs), those differences are controversial, at best, scientifically unsound at worst. All the rest of it is concerned with music players delivering exactly the same digital data to exactly the same DAC to exactly the same analog playback system, and somehow sounding audibly different.
#PURE MUSIC MAC INSTALL#
If you have non-Redbook files in your collection, I'd install Pure Music, as OSX requires that you manually re-set those parameters in Audio Midi Setup, then re-boot iTunes. This cannot happen with optical or wireless. The theory is that computer activity generates electrical noise that is carried by the digital cable into your analog system. That will eliminate, in one simple and easy step, 90% of the problems that are meant to be addressed by most server tweaks (software/OS minimization, SS hard drives, etc). I'd personally choosei a DAC with really good optical implementation as a starter, for the galvanic isolation. Note that the current limitation using this setup (Mac and Ayre), is 24bit/96khz, if that is important to you it's not to me. I also use the $4.99 Rowmote application to shut down.
#PURE MUSIC MAC FREE#
You can use an i-Pod or i-Pad to control your music via the free Remote application. Regardless, i-Tunes currently does not automatically adjust to play different resolution files, while Amarra does. Some people, on some systems can't detect any sound difference between Amarra and i-Tunes, but I can on my system. I also use Amarra software, in order to bypass the i-Tunes sound engine. The post ringing filtration type is user selectable. The DAC also has some combination of pre and post ringing filtration (Minimum phase, apodizing). This DAC uses asynchronous transfer mode, which from everything I've read, is really good to have if using USB input I think it really lowers the jitter. Since I use USB output, instead of firewire, I use an Ayre QB-9 DAC. I'm using a Mac Mini as a music server and think it is a good idea.
