Here's a link: http://www.audio-gd.com/Pro/Headphoneamp/NFB12/NFB12EN.htm
I'd also check out the local thread here: http://www.head-fi.org/forum/thread/524263/audio-gd-nfb-12
NFB-12 has optical, coax, and USB, while the E7/E9 is USB only.
Also, I believe the NFB-12 is considerably more powerful amp-wise in comparison to the E7/E9. It has a dual WM8741s as opposed to the WM8740 in the E7, but I'm not sure what the difference is exactly sound-wise between those two models. I believe the sound is fairly neutral. I'd recommend the NFB-12 if you don't need the portability of the E7/E9 combo, which has the hassle of being two separate parts.
Hi. Thanks for the response. Yea I do not need the portability being that it more for home use and I am lookign to hook it up to my Onkyo 705. I was hoping that my 705 would be sufficient but I guess not. Ima have to splurge for an amp, this sucks.
