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-10D. The capacitor upgrade kit comes complete with a comprehensive 3 page manual with diagrams and is very easy to perform if you know one end of a soldering iron from the other!

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 ELNA RE2J caps have been selected for their liquid, smooth flowing sound, their low ESR (equivalent series resistance) and long life 105C rating. The non polar caps have been selected because they sound a lot better than directional electrolytics. Polypropylene input coupling caps are by RIFA and film output caps are a huge 4.7uF which provide a much larger soundstage with bags more bass!. An exceptional upgrade for your X-10D!
