Received my DT 770 pro 80 ohm for a week now. Using the astro mixamp, I compared it to my ATH A900. Honestly, I am a bit disappointed. A900 sounded much fuller compared to the DT 770. However, DT 770 edges out the A900 in the bass department. The bass has much more depth and impact. Even though I am disappointed in the DT 770, I can still see the potential of these phones for immersive gaming. From your post, you suggest using the Fiio E11 along with the mixamp when using headphones with high impedence. I read somewhere that double amping is a no-go for sound quality. Is this true? Also would using E11 along with the mixamp help the DT 770 beat the A900 in terms of both immersive and competitive gaming? Lastly, how do you hook up Fiio E11 to the mixamp? Sorry for all these questions. I am still quite new to all of this. Thanks for this great thread and the double post.
Well, the DT770 Pro 80 treads on muddy quite a bit, which is why I'm sure you're disappointed. I've mentioned it various times. It's not a very clear sounding headphone. What it excels at is bass prominence and closed soundstage/positioning. It will NEVER be good for competitive gaming due to it's bass mucking up details. I mention this on my review. Sigh. That's why competitive score isn't good. For just a little more, the DT990 Pro is noticeably better to me, though it's open.
The DT770 Pro 80 can sound full, but you need amping. The DT770 Pro 80 is easiest to drive, and I assume the E11 would be beneficial, though I'd rather get a Fiio E9/E9K. All Beyers on my guide need amping. No ifs, ands, or buts.
Double amping is the ONLY way to get hard to drive headphones to sound good off the Mixamp. Yes, it will be better than not double amping at all. Double amping is overblown on head-fi. The same is done in audiophile terms. It's called pre-amping. Just, in this case, you're amping out of a headphone jack into another.
