You if are going to using a lot of different headphones, the Magni is a better choice. It's always going to be quiet, i.e. noise free. The only issue with the Magni, and others have noted this, is that it can be slightly bright, therefore not necessarily a good match for brighter sounding headphones. However, keep in mind that if your headphones happen to gel well with the Vali, the Vali is so much better sounding than the Magni.
