That being said, the importance is in whether YOU like the feel/sound of the instrument, and not letting yourself get bogged down dwelling on "whose fingerprints were on the wood?" during the build process. People don't insist on driving cars hand-built by Henry Ford's or Louis Chevrolet's direct descendants, or only flying in aircraft made by William Boeing's great-grandkids.
It's a sure bet that Teodoro Perez himself doesn't make the Madrid line himself. He came up with the design specs for it. Therefore, whether the actual builder is working from these specs in the Perez shop, or across the street, or in another town, is all pretty irrelevant.
