Clip+?

I hear the Clip+ is very highly regarded around here, but I have a question. I've been looking, and I can't find a LOD for it. I have heard the DAC is very good, but would I be able to connect it to an external DAC such as the E7?

No

What would offer better SQ?

iPod Nano 3rd Gen>320kbps MP3>FiiO L9 LOD>FiiO E11 (or comparable amp)>RE0's

Sansa Clip+>FLAC>3.5mm Male-to-Male>FiiO E11 (or comparable amp)>RE0's

Difficult, I dont know, I have went back from using my portable amp with the Clip+ because my headphones are as good as with the amp..
