Guarantee
This kit is covered by your 60-day satisfaction guarantee. Install the kit, give it a month to burn-in and sound it’s best, after which if you decide the cost isn’t worth it, reinstall the original parts and send the kit back for full refund, we pay return shipping.
How Long Does This Take?
2 hours of labor, 12 hours of letting the adhesive cure. Most will take about an hour to disassemble the pair of speakers, then another hour of labor to install and reassemble. This is a pretty easy swap out and the video is shot without much in editing, giving you a good idea of time and difficulty.
What Tools Are Needed?
Clean tabletop and blanket or pad, so you can operate on your speakers as they lay speaker drivers up
#1 square drive screwdriver (some builds)
Torx T20 drive screwdriver (some builds)
Soldering Iron (2 - 4% silver bearing solder is recommended) (some builds)
What Are The Sound Differences Between The Standard, ClarityCap MR, And Jupiter Copper Foil & Wax?
Compared to the base model’s basic polypropylene capacitor, the Jupiter Copper is much more relaxed and smooth sounding, all while raising resolution. The combination of reduced noise and improved transient response let you hear deeper into the sound field—improved stereophony, better timber of brass and percussion-heavy instruments, more revealing vocals, improved tone and color resolution of string-based instruments—a very nice bump in smoothness and holography, where the recreated sound space is more “reach out and touch you” and buttery, without sacrificing any detail in resolution.
