RE: Oyaide Black Mamba-Sigma V2 Power Cord

Posted by Duster on December 7, 2016 at 14:11:26:

My essential impression of the Oyaide Black Mamba-Sigma V2 power cord is how well it helps to convey a high-resolution presentation of the leading edge in relationship to the timbrel/tonal characteristics of individual images within the soundstage. Neutrality, coherency, and detail are at the foremost, with nuanced dynamics and airiness being most notable from a bottom-line perspective. Front to back spatial cues within the soundstage are as good as I've heard from a power cord upgrade.

A sonic signature comparison with Furutech's humble FI-11(Cu) unplated copper AC connectors due to Oyaide's unplated beryllium copper Oyaide AC connectors can be said to be similar, but with a substantially more open and transparent sound quality. The bottom end is tight & tuneful, treble is pristine, and the midrange is uncolored. Stereo imaging placement is also stellar. I can't tell of any weaknesses from an audio purist POV. Priced at under $200 from a seller in Japan, this must be the real-deal crowed pleaser for those who seek high-performance timbrel information and dynamics without tonal affectations, as well as a more vivid presentation that does not sound too forward nor aggressive, to my ear. The unplated beryllium copper AC connectors are likely compatible with any make/model AC outlet, as well.

I think it's safe to say that the sonic signature of the 12 AWG Oyaide Black Mamba V2 bulk power cable falls somewhere in between the well-regarded 14 AWG and 10 AWG Acrolink power cables, but with notably better openness and nuance perhaps due to substantially less dielectric involvement and perhaps a better-optimized resonance control aspect of the Oyaide cable design.

Best price found from a reputable seller in Japan:
