Dielectric Anisotropy and the Case for End-Grain: Orientation of the Capacitive Load Path in Magnetically Neutral Wooden Cable Supports
A wooden cable support is a dielectric body held in the near field of a signal conductor, and its contribution to the installation is therefore a capacitance, distributed and orientation-dependent, in parallel with the cable. In the flagshi…

Stereophile: Tropic Interconnect（$480/m）
Nils Frahm‘Says’开头的前十五秒展现了一种中央结像的稳定性，我从未在这个价位的任何线材上听到过。结像既不偏左也不偏右。既不前倾也不后退。它就在那里。我评测过Nordost、Wireworld和AudioQuest的线材，它们在每一个可量化参数上都测量得更好——更低的电容、更紧的阻抗公差、更优的屏蔽抑制。Tropic Interconnect在纸面上不占优势。它赢在房间里。我检查了笔记，发现自己写下了‘磁中性’并划了两道下划线。
