Edit: The only cable you will need is a simple 3.5mm (small headphone jack) to RCA (red and white) cable. Easily picked up in places like Radio Shack or online retailers like Monoprice.
allow me to clarify some confusion regarding needed cables:
e9+e10
e10 connects to Macbook via supplied USB cable.
e10 line out connects to e9 line in through a 3.5mm to 3.5mm cable. this is not supplied and you have to purchase one.
e9+e7
e7 docks into the e9.
e9 is connects to Macbook via supplied USB.
Comments:
I originally bought the e7, and returned it because I did not notice any difference between it and playing music directly out of my Macbook. It did have a nice bass boost, but constantly turning the device on and off became annoying.
Next I bought an e10 and enjoyed it quite a bit. You just plug it in via USB and it turns on and off when your computer turns on and off. The sound was nice (though I'm not sure if I heard much improvement over my Macbook), but the bass boost feature on it was great.
Lastly, I bought the e9 to pair with the e10, and together I DO notice a difference in sound. The bass is punchier and the music feels like it has more energy. I use the e9 (amp) +e10 (DAC) as a desktop combo, and bring just my e10 (Amp/DAC) on the road with me when I travel.
Additional Notes:
-the e10's bass boost can not be used while it is paired with the e9, but the bass is still great with this combo.
-fiio sells a 3.5mm to 3.5mm cable to connect the e9+e10 (the fiio L2), but i feel that the cord is a bit to small to have the e10 sit at the front of the e9, so consider buying a slightly longer cable.
-esthetically, i prefer the e10 sitting on top of the e9, compared to the e7 sticking up docking into the e9.
-i also have the HD 600's and they sound great with this combo.
I'm not saying the e9+e10 combo is the best option, but I have it and enjoy it. I've read that the Schiit Asgard pairs real well with the HD 600, and sells for $250. So look into this Amp (no DAC though) as an option if your budget allows.
