Unless there is something really off with your cable it is not that. The smallest guage wire that you own will carry the full audio frequency range, and at line level the full voltage swing. Audio interconnects carry very little current and can be quite thin or quite long before something bad happens.
These are not compressed mp3's, but I have tried using a 4th gen video ipod and 5th gen? itouch and the results seem to be the same-flat sound through semi-decent audio equipment.
I don't keep up with this but I think that all MP3 files are the product of a lossy compresion process. ACC is better and WAV better still, but if you're ripping it and the end file is smaller than the original it is compressed.[/quote]
The headphones do show an improvement, but it seems harder to accurately evaluate sound when it's right in your ear bud.
Headphones do increase percieved bass because of the close coupling to you ear. But with most headphones, especially with buds, it is mid bass that you hear and not the lower harmonics of the bass drum or the piano.
I borrowed my wife's Zune (loaded with ripped CDs) and dock and plugged it into the front Aux2 input on the 906. I used the included audio patch cord (which seemed well made).
I immediatley noticed a drop in volume and raising the volume level on the Zune to the max it was still lower than I would have expected.
So I cranked the gain on the 906 to -5 dB (usually it is at -25 or so) and found the sound to be lacking in bass. I switched to the rip of a Telarc CD and it was "flat". The bass drum was there but it lacked bottom, almost as if there was a filter in place at about 80 Hz.
I listened to the CD itself and it was much more dynamic, a greater range and more punch in the bottom octaves.
A number of people on the web are saying things like this--To create an MP3, a computer samples the music on a CD and compresses it into a smaller file by excluding the musical information that the human ear is less likely to notice. Much of the information left out is at the very high and low ends, which is why some MP3s sound flat. Cavallo says that MP3s don't reproduce reverb well, and the lack of high-end detail makes them sound brittle. Without enough low end, he says, "you don't get the punch anymore. It decreases the punch of the kick drum and how the speaker gets pushed when the guitarist plays a power chord."
I am inclined to think that this is not a 906 issue.
