Interface WiFi through the Ethernet port using an external wireless router.Turn off unused wireless control interfaces such as infrared, Bluetooth, and WiFi.Isolate input music data, output music data, and software commands on an independent data buss.Use high-performance shielded data cables (USB, Ethernet, etc).Independently power any external drives, switches, routers, and converters with an ultralow-noise linear power supply.Use a large capacity internal MLC SSD or external NAS/RAID array with MLC SSDs for your music library.Order 2014 and newer Mac Minis with the smallest mSATA SSD card option for OS X and player software.On pre-2014 Mac Minis upgrade one HDD to a low-capacity (64GB) 2.5' SLC SSD for OS X and player software.Order 2014 and newer Mac Minis with a minimum of 8GB of RAM.On pre-2014 Mac Minis upgrade RAM with a minimum of 8GB of low-latency RAM (CAS 9 or better).In addition to upgrading the stock SMPS, the more of the upgrades listed below you make, the higher performance you will have: Replacing the stock SMPS that powers your Mac Mini with a low-noise linear power supply will make more of an improvement in performance than SSDs, upgraded RAM, OS X optimizations, player software, and anti-resonance upgrades all combined. When the SMPS noise is eliminated, the result is cleaner and more defined “square waves” in the digital signal, which translates to fewer bit read errors, less error correction, and less jitter. The most significant upgrade you can make to you Mac Mini is to replace the stock switch-mode power supply (SMPS) with a low-noise linear power supply.
