This upgrade kit has been selected aftermany hours (years in fact!) of critically evaluating parts and is guaranteed to bring out the best possible sound quality from your X-Can V3. The capacitor upgrade kit comes complete with a comprehensive 4 page manual and is very easy to perform if you know one end of a soldering iron from the other!

UPDATE: Kit now incorporates the ultrafast diode mods which, together with the cap mods, transform the V3 into a truly mind blowing amp!

The parts in the upgrade kit have been chosen specifically for their sonic attributes and are not just a handful of uber expensive "boutique" parts that look good. The Panasonic caps have been selected for their liquid, smooth flowing sound, their low ESR (equivalent series resistance) and long life 105C rating. The CD71 and CapXon 105C non polar input & output caps have been selected because they sound a lot better than directional electrolytics. Film bypass caps are by EVOX /RIFA. An exceptional upgrade for your V3!
