I have an iPod Classic (the last generation), and the Sony XBA-4.
The iPod's sound is correct, but that's all. So, I was wondering if it could be enhanced...
Besides, the iPod classic has an output impedance around 5 Ohms. My earphones, the Sony XBA-4 have an impedance around 8 Ohms.
As you may have noticed, the combination iPod Classic + XBA-4 is... flawed. The output impedance of an earphone should be 8 times beyond the output impedance of the source ( Am I right ? ). So, the output impedance of my source should be around 1 Ohms.
So, I thought of the Fiio E1. It's really small, and is supposed to enhance the sound.
Has anybody tried it ? Does it really enhance the sound ?
And what is the output impedance of the Fiio E1 ?
Thanks for advance :)
