Cool. I have extremely high hopes for the DT990/600. I have been reading up on them like a LOOOOOOOOOT. I don't think I've ever been this excited about a headphone. Reviewers, audiophiles, and non-audiophiles alike have compared them to many higher end, comparitively priced, open, closed, and what have you. The DT990/600 are extremely well received throughout.
I was blown away by how prestigious the sound was off the DT880, and I expect even more from the DT990 as it's more to my liking as a slight bass/treblehead.
The one review I saw comparing the DT770 Pro 80s vs the DT990 made the 770 Pro 80s sound like they were nearly low fi compared to the 990s. Pretty much improved in every aspect I wanted from the 770 Pros, which was clarity, bass refinement, soundstage, and overall wow factor.
But hey, I pretty much prefer the Creative Aurvana Live over the DT770 Pros in every way except soundstage and positioning.
I am VERY impatient and can't stop thinking about the damn 990s. >_< I was SOOOO close on getting the DT770/600 instead, but I figured the CAL already does everything I could want in a closed headphone...not to say that the 770/600 couldn't probably best it in every way. Figured I'd spend my money on another type of sound altogether.
Meanwhile, I have been playing a bit more Star Ocean on the PS3 with the K701 hooked up the the E7 after the Mixamp. The E7's bass boost 1 is considered to be a slightly warmer version of bass boost 0, and I agree. The bass is warmer but not 'emphasized' much more. I found it to work EXTREMELY well with the K701, and fixed the K701's lack of bass without altering it's clarity or overall signature with the exception of it being just a smidge warmer than they were. I'd say they sound like the DT880's now but with more soundstage and obviously better positioning.
I wish one of you could test out the K701/2 with the E7 after the Mixamp. I'm not crazy. It sounds fantastic. I have my Mixamp at about 90% master volume (fully on Game), and the E7 at about 35-40 out of the max 60 in volume.
It's a blessed experience, and I have a hard time believing a REAL amp can offer a huge upgrade in SQ compared to it. I'm obviously just assuming, but there is nothing underdriven about it's sound.
That being said, the E7 OBVIOUSLY can't drive the K701 efficiently when I have it hooked up to the laptop or Fuze. It's only with the Mixamp that I feel the K701 is missing nothing. Of course, this is all based on not having voice chat enabled, as I always stress to mention.
I will applaud the Mixamp for being able to make the K701 sound as good as it does compared to everything else I have hooked it up to (including receivers), and it's a great pair for the E7 for the K701.
I cannot WAIT for the E9. Fiio has a dedicated customer in me, and I hope they continue to deliver such great price/performance ratio in the future.
Just look at reviews on the E7 by people with much more expensive dac/amps. They all mostly agree on how good the E7 really is.
Whomever it was that recently bought a K702 and the E7, please give us your opinions on the combo with the Mixamp.
