When I bought my first Koetsu, a slightly used Black in the early 90s, I didn't think of rebuilding costs before or after I bought it. It was the sound, the way it conveys music, that drew me to it. Prior to that, I have used AT312, Grado 8MR, Monster Cable Alpha 2, Madrigal Carnegie 1, mostly from reviews of magazines. I was always restless and always found something missing. Then a friend offered a Lyra modified Koetsu which I had posted here earlier. Still was restless, till the Black , and I never looked anywhere ever. I then took the country distributorship in the 2005 and bought myself a Rosewood Signature, it was the only house sound that I would 'upgrade to'. IME as a distributor, 100% of rebuilding jobs were results of 'destroyed by the owner or his house help. So it was actually a useful outlet or option rather than junk it, sell it low, or retip is from 3rd parties found in the net or elsewhere. Those who retipped not from Koetsu either ended up not using it or selling it. We can only assume why. One such job was shown to me and the cantilever not only has a different color but a different angle, a much larger one. They couldn't muster enough to pay for the real rebuilding price, which is their right. Some bought an almost dilapidated 70s long body for cheap, hoping to swing it for some good price but found out that the suspension no longer works correctly. Naturally, they will not pay for the Koetsu rebuilding price and some just kept it, and others sell it as it where is to someone who is willing to have it rebuilt by Koetsu. It's all a matter of choice when it comes to how people want to shell out their money.
