"Most portable devices are powered by USB and their power supply is limited to 5V. This means the output of the signal is limited to the maximum of 5V. On the other hand, a full scale component like a CD / DVD player has no such constraint, a standard CD player will happily output signal at 24V (+/-12V DC)
A standard amplifier that is designed to accept the standard 24V line input is going to struggle to deal with the 5V input. The end result is a 100W rated power amplifier struggling to produce 23W. That is why it does not sound right!"

I don't feel like commenting too much, you should at least spot the obvious. Maybe next time.
