12VDC low-noise linear power supply with big toroid transformer, ample filtering, high-speed soft recovery diodes, a 3A Belleson voltage regulator, and CONNEX Carbon Fiber, Gold-plated DC Connector, (5.5mm OD x 2.1mm ID).
Both cables are shielded and teflon-insulated, and are both hard-wired. The power cable is about 3-ft long. The DC cable is about 4-ft long. (I placed the power supply on the floor beneath the equipment rack.)
Performance is as expected: Fast, bigger sound, lower background noise.
$225 shipping included.
