French high-end media specialist R_volution has launched an innovative DIY upgrade kit that transforms the popular Sony UBP-X700 4K Ultra HD Blu-ray player into a genuine audiophile-grade component. The R_volution Chassis DIY-X700 replaces the stock switched-mode power supply with a high-performance linear power supply, promising significant improvements in both video and audio quality for discerning home theater enthusiasts.
The Sony UBP-X700 has long been a favorite among budget-conscious cinephiles for its excellent 4K playback, Dolby Vision support, and reliable performance. However, its stock power supply has been a common point of criticism in high-end circles, where electrical noise can subtly degrade picture sharpness, black levels, and digital audio precision.

R_volution addresses this directly with the Chassis DIY-X700. The kit includes a beautifully crafted new enclosure housing a massive 81VA oxygen-free copper toroidal transformer, audiophile-grade capacitors from Nichicon, Nippon Chemi-Con, and WIMA, and precision voltage regulators from Toshiba and Lintec. According to R_volution, these upgrades deliver a cleaner, noise-free power signal that results in deeper blacks, more vibrant colors, exceptional image sharpness, and superior multi-channel audio dynamics.
Installation is designed to be user-friendly: owners simply open their UBP-X700, transfer the mainboard and optical drive to the new chassis using provided ribbons and cables, and follow the included detailed manual and video guide. No soldering or advanced technical skills are required, and the process reportedly takes just minutes.
