Sound Analysis (Compared to Stock Cable)
The sub-bass has slightly more quantity and it aids in the overall sub-bass reproduction. Bass decay is quicker and there is extra punch from the rumble. The rumble helps to improve the dynamics. The mid-bass has similar quantity with the slam maintaining its control. Bass texture improves slightly.
The midrange has less body and its transparency improves slightly. The lower mids has less quantity and the reduction in the body prevents male vocals from being expressed in a thick manner. The upper mids improves with slightly more forwardness. The crisp is maintained. Female vocals become livelier.
The treble extension maintains at a similar level. The amount of body is being kept and the treble has a brighter presentation. Treble is articulated with similar precision. The amount of air rendered has a slight improvement and the increased quantity helps to give a more open feel at the top end. The sparkle and crisp are maintained.
The soundstage width increases by a little and depth is maintained.
The Penon SPC is an affordable cable that helps to add some liveliness to the overall sound. The soundstage improves slightly. In addition, there is great visual appeal with the parts used. For those who wish to upgrade their stock cable and do not wish to spend a lot, this is a cable to consider.
