I am a headphone-centric audiophile
15" MacBook Pro w/TouchBar (2016)
2.7 GHz Quad-Core Intel Core i7
16 GB 2133 MHz LPDDR3
macOS 12.2.1 (21d62)
The MBP feeds a Thunderbolt 3 PCIe expansion chassis via a WireWorld USB 3.1 cable, positioned at the top of the systemâs 3.1 bus hierarchy⌠I use the WireWorld USB3.1 cable instead of Thunderbolt 3/4 cable because of itâs superior design architecture and performance as compared to a standard high-quality TB 3/4 cable⌠The expansion chassis hosts an ElFidelity AXF-107 âMagicianâ Max Power Purification PCIe card, for power/noise filtering/conditioning/stabilization, and hosts a Sonnet Technologies four-port USB 3.1 card with four independent controllers, using only one output⌠the other three are screened with AudioQuest USB caps.
The USB 3.1 output from the Thunderbolt 3/4 PCIe chassis feeds and powers an iGalvanic isolation/filter/re-clocker, via a WireWorld USB3.0 cable⌠the iGalvanic feeds my TEAC DAC via a WireWorld USB2.0 cableâŚ
The entire system architecture resides on, and star-grounded on, itâs own power âislandâ, being quad-filtered and augmented by an ADD-Power EAU2 harmonic resonator on the mains power, for extreme noise reduction. The power cables to the DAC and my HPA are WireWorldâŚ
I use USB 3.x cables because the signaling-lines are separated from the data-lines in the cable architecture. (no adapters)⌠The USB2.0 cable is a very short lead to the DAC.
Audirvana Studio 1.11.0 is configured with SoX enabled for modulation of PCM to DSD128 being fed by 112DBâs âRedline Monitorâ HTRF audio-units pluginâŚ
My library HDD lives at the top of the hierarchy of the systemâs USB3.0 bus architecture⌠I find that separating the HDD USB3.0 data input feed from the USB3.1 data output feed to the PCIe expansion chassis, provides an audible improvement in sound-quality, most likely due to noise/jitter reduction from various operational interference.
I take great care to remove electro-mechanical interference and RF and EMF interference through a diligent and conscientious approach to noise mitigation/suppression. My cable internet feed passes through a Jensen galvanic isolatorâŚ
This works for me in my unique personal system environmentâŚ
