Well, that is somewhat true. But more bit depth is needed as we process more DSPs into music, to avoid things such as data loss or clipping. 
 
Now, the point is that portable devices, such as music players cannot process a 192KHz track, or a 32 bit one and add an EQ over it, because the data rate is too high for our portable units. 
 

I would love to k own how to EQ properly on a dx80 and on a pc. But does it distort my chord mojo?

You're trolling.

Well, I guess that's true, but only because DAP's don't typically have top of the line processors in them. Pretty sure a top end Snapdragon wouldn't have any problems with that.

Maybe. I think you are right. The problem, though, is that including both top of the line DAC and top of the line CPU and other things would consume enormous amounts of energy, making the DAP either have little battery life or huge size to have a big enough battery.

Top of the line DAC's are a complete waste. For years every DAC has been capable of producing transparent output, so that's not an issue. A good class D implementation for the amp would be the way to go, just bypass a DAC completely, you can get a decent amount of power with lower energy consumption that way.

There's a few "how to equalize" threads on head-fi, including a few of my own
http://www.head-fi.org/t/413900/how-to-equalize-your-headphones-a-tutorial

http://www.head-fi.org/t/796791/the-most-reliable-easiest-way-to-eq-headphones-properly-to-achieve-the-most-ideal-sound-for-non-professionals

I must say, it's actually a very complicated topic with each tutorial having its pros and cons, I don't know which to recommend. And what equalization capabilities does the DX80 have anyway? Is your rockboxed or?

As for distorting, no I don't think that should happen--the Mojo will just decode whatever it is fed, whether it's the unaltered signals or the equalized signals. Although, digital clipping can happen if an EQ is mismanaged. Mostly you just have to look for a preamp setting and lower that when you're boosting frequencies. If no preamp slider is present, just avoid boosts in general and cut other frequencies instead when you want a boost.

A lot of consumers in this segment think if your DAP is not using a desktop-grade DAC that's using as much power as an octa-core Snapdragon and an even more power-hungry amp you're not getting good SQ, let alone value for your money...

Oh, I know. I'm just saying for me, a good Class-D seems to be ideal. I know that in this segment, it would be poo-pooed. I am just one of those peons that streams music, though. I still like to have a separate device from my phone for audio, and Sony's or an X7 are really the best by for me. Then I get these ideas in my head that lead to me owning an A&K AK300. 
 
But now I'm off the subject of the thread. My main purpose in replying was that I think the idea of pushing beyond 24-bits is just insane. 64-bit audio? How will that suddenly improve things? Seems like a bad idea to me. It seems to me that your original premise was correct, and that 64-bit audio would be even worse for audio than DXD. I mean, are we considering weaponizing our DAPs?

And that is somewhat a problem for this hobby. We end up with DACs that are hard to implement sometimes, and are not ideal for portable usage. 
 
But in the end, using that top of the line will yield an improvement. Now how big it is, and if it is worth it, are two different questions.

I think George means to upsample the bit depth for the DSP processing, which could be necessary/audibly different depending on what processing is being done.
