Not really. You just have the next edition or better hearing aid. The Resound Linx was the original hearing aid. When they upgraded it - it became the Quatro. The company didn't have it when I bought my aids then. In the world of hearing aids, all companies are developing new technology to get a close to being like our ears/brains. When they are able to develop new ideas, they test them out in beta aids and then if they are successful, they add them to the new upgrades.
