I am using DT880 250 on my computer. I wear these 8+ hours a day while I work and game. I use them for music and gaming almost equally.
I was using Xonar STX w/ upgraded OpAmps, but I am looking at switching to a DAC/AMP to better quality sound.
My motherboard has a 110db SNR RealTek 898 with support for SoundBlaster X-Fi Xtreme Fidelity and EAX 5.
I'm using the motherboard audio right now while the STX is being sent to Asus for replacement.
I had a few questions though I can't find answers to.
From what I understand, the E17 will drive the DT880 250 and sounds great, is there any benefit to adding the E09K to the setup?
If using SPDIF for the computer, is this less quality than if using USB and completely bypassing the sound card? I originally planned on doing USB to eliminate the sound card all together, but reading I see that using SPDIF will allow me to get some functionality of the on-board sound. Does this mean I will keep full positional audio support from my on-board and EAX? Would it be less quality than using USB only?
Will I need a SPDIF optical cable, or does it come with it?
Is there a way to put an additional 3.5mm inputs into this? I have a Windows box (I would use USB or SPDIF), OSX Box (3.5mm) and PS3 (3.5mm) I would like to have all three inputs tied in. Right now I'm using the Input jack on the STX with a 2-3.5mm->1-6.35mm splitter so I can use all three into my DT880.
