Can I double AMP with a wireless mixamp and an E9???

Depending on the Ohms.
 
DT990/600 NEEDS double amping (E9 for example) since they are very hard to drive

Yes. Just connect the wireless mixamp's headphone output to the input on your amp.

Not sure what you mean by "depending on OHMS." Sorry I'm a newbie to this. So basically will the DT 990s be require a double AMP? I'll be mainly using them on consoles. Also, if I'm looking for a more SQ type headphone wouldn't it be better to go for closed headphones? I think the DT 990s are open? Correct me if I'm wrong.

Easy to drive headphones (iBuds, PC360, Creative Aurvana Live) are ~ 50 Ohms.
They don't need an amp... at all.
 
There are some headphones that are 80 ohms, 250 ohms, 600 ohms.
 
The bigger the number, the harder they are to drive, so for 600 Ohms an amp is a MUST.
 
DT990 (for example) has flavors of 32, 250 and 600 Ohms
 
Depending on the number, the sound changes a little. The most audiophile version is the 600 ohms, but basically, each has a different sound.
 
So, if you want more SQ concensus is to get the 600 Ohms of DT990 (IMHO, YMMV, etc).
 
Is just get zo2, pc360 and be happy, hahaha (i have not used zo2 myself, but read do wonders for bass).
Don't remember if 32 and 250 ohms headphones need an amp after mixamp

There are different versions of the DT990. 
 
32 ohm: http://www.amazon.com/beyerdynamic-990-Premium-32-Headphones/dp/B0024NK344
 
250 ohm: http://www.amazon.com/beyerdynamic-990-Premium-250-Ohm/dp/B000F2BLTW
 
600 ohm: http://www.amazon.com/Beyer-Dynamic-Premium-600-Headphones/dp/B0024NK34O
 
 
Basically, impedance (measured in "ohms", symbol: Ω) is the resistance to electricity. Higher Ω means a headphone is harder to power, but it also has some benefits. Without getting into that, all you need to worry about is the fact that the Mixamp will have a hard time powering anything over 250 ohms, especially if you mix in some chat volume.
 
The other factor you have to worry about is sensitivity, which is the amount of volume you can get out of a given amount of power.
 
So basically... an amp can do X amount of power into Y ohms, and this, combined with your Z sensitivity, will tell you how much volume you can achieve out of a given headphone and amp combination. Higher ohms will give less volume on any given amplifier. Lower ohms will give more volume.
 
 
To put it in simpler terms: The DT990 32Ω will not need a second amplifier. The 600Ω will.

I dunno, the DT880/32ohm felt harder to drive than the DT990 Pro 250 ohm. Seriously. Beyer 32oms felt lacking considerably when unamped. Though that's in terms of non-gaming performance. The Mixamp will drive 32 and 250 ohms loudly, though that's without voice chat mixed in.

Is the wired mixamp you talked about in the first pages mixamp pro ?
 
I'm wondering if mixamp pro has the bass enhancer that mixamp 5.8 has.. and also if it is wired, because I really don't want to switch batteries when gaming. also less hissing would be nice.

 

[Mad Lust Envy]

The Mixamp Pro is the wired Mixamp. That's not a bass expander button, but the DH Mode button. The Pro doesn't have a bass expander. It wasn't called the Pro until recently. They renamed it to identify between the wired, and wireless.

Check the official product pages, it should clear up a lot of questions you may have about the MixAmps.

Great info! Thank you. So they are different tiers of the DT 990s? Tiers divided by OHMS? Would you consider the. I can't find the zo2s on amazon. Which are better for SQ? DT 990s or zo2's?

The Zo2 is an amp/equalizer. It's not a headphone.

 

[jghost23]

Oh ok, why would I need a Z02 on top of my mixamp for the PC 360?? I thought it didn't need double amping.

 

[obazavil]

zo is a kind bass enhancer

I thought they renamed it to make it a bit more distinct from the older A40 Mixamp revision, which also has some changes to the knobs (they're not beveled on top on the Mixamp Pro). The functional differences seem to be more robust USB capabilities for PS3 and PC users.
 
If there's even more small revisions on top of that, they sure don't make it clear as to what's changed...

 

[jghost23]

I apologize if this is a stupid question. But if I use the wireless mixamp, will the PC 360 be powered by the mixamps batteries?
