Deep Sea Blue
This is the Deep Sea Blue vinyl pressing of Jihyo's Zone album. Pressed on a 12-inch record at 45 RPM, this format is a step above the standard 33⅓ — the faster rotation means wider groove spacing, which translates to improved dynamics, richer detail, and a noticeably wider soundstage. Audiophiles specifically seek out 45 RPM pressings for this reason. The Deep Sea Blue vinyl makes it a visual standout too, and as a limited TWICE release, it's as much a display piece as it is a listening experience.
