I know of no other company that champions the benefits of abundant capacitance in audio component power supplies quite like Angela-Gilbert Yeung. The manufacturer often designs with upgradable power-supply paths in mind. But this time was different. While the power supply remained central to the company’s design ethos, in this demo it took the form of a single power source driving core components—a setup George Taylor of Entracte Audio, and spokesperson for Angela-Gilbert Yeung, dubbed the “Integrated Separate System.”

The term refers to the company’s C312 preamplifier (US$ 6300), A210 power amp (US$ 5250), and AM205 power amp module (US$ 3250) being operated in an ISS configuration, meaning their power supplies were linked together. When I asked whether isolating the supplies wasn’t preferable to avoid power irregularities caused by a shared supply serving multiple components, George countered that the Integrated Separate System offered a cleaner, more stable approach. In a conventional setup, he explained, multiple supplies constantly fluctuate in response to their individual power demands, whereas a single, unified source maintains steadier performance across the entire system.

Rounding out the demo were a DELA (Melco) N5 music library/streamer ($11,500), a pair of Fink Team Borg loudspeakers ($46,000) and a suite of Angela-Gilbert Yeung products: a D521 DAC (US$ 5150), SCK4 Soundstage Shape Control unit (US$ 1000), an ISS-SP Cap Pack Link cable (US$ 275 / 2m.), and an ISS-FCF Link cable (US$ 275 / 2m.), as well as several of the company’s accessories and cables.

As they say, the proof is in the pudding, and the pudding here was tasty. What I heard was unwavering purity and musical ease, along with instruments, such as guitar and sax, that sounded lifelike, imbued with sweet, authentic tone and corporeal presence. Transparency was off the charts, exposing a panoply of harmonics and melodic threads.
