Yes I mean those cables thanks :)   What I'm saying is basically that when I use the 3.5mm interconnecting cable and I max the volume on my iPhone, the volume with or without the E7 (also maxed) is the same. And that seems strange to me because then it doesn't amplify at all..    ...

I'm very happy with my E7 though I'm pretty curious about this: If I plug the E7 in my iPhone using the audio cable I don't seem to get more volume. I need to use the special iPhone cable to get some extra volume. Is that normal? It seems strange since the E7 is an amp and all...
