Both ipods have been bough in europe so they should have the volume limit in place. My nano clearly outputs a lot more volume (with the same headphones ofc) than the classic. My classic also seems to be quieter than the original one that I had (it's a refurb that apple gave me after the original one hdd died). The nano also sounds better (using sennheiser ie 8). Am I dreaming or my classic is defective? Is there any way to test the ipod output?
