Reply to DJM-800 vs DN-X1700 opinions

Hey guys!

I currently have a DN-X1500s, and am looking to upgrade. For my price range, I've come up with the DJM-800 and DN-X1700, but I'm having trouble deciding which one I want to replace my current mixer. What are your guys opinions on these two mixers? Here's a rundown (in priority order) of what I'm looking for in a mixer.

1. 4 channels
2. Reliability/overall quality construction
3. Sound quality
4. Effects (effect quality)
5. Digital-ins
6. Loud headphone amp
7. EQ quality

Let me know what you guys believe. Any info is appreciated!

Thanks,
Jaeros
