Choosing a sound card is an important decision for a musician. RME sound cards (audio interfaces) are of high quality sound. But there's a learning curve coming with them and some incompatibilities with some softwares on Apple products. Only testing and others reviews can provide all the information we need in a purchase decision. Always ask for references when you can. It might not change your decision but you will have a better sense of reality. In complexe situations - when there are many variables - it's good to have a plan and priorities to refer to. Here, my priority is to get the best quality possible despite reasonable time and costs.
