I had Sound Smith repair my Dynavector 20xl after it suffered a hit from some indoor dodgeball my kids decided to play. I went with the tip upgrades and am very happy with it (I can't remember which option). It's been said, but make sure you plan on a 10 week or so turn around. That said, I would do it again (but hopefully I won't have to). Great service, great product, go for it.
