The combo "Odac + Neco V3" is very well-praised:
NECO SOUNDLABS PORTABLE V.2 AMP

"ODAC + NECO V.3 + Sennheiser HD580 = A MATCH MADE IN HEAVEN.
I can't tell you how beautiful this rig sounds. We all know how well the HD580/600 scales with better sources and amps.. but synergy is often undervalued. The ODAC is beautifully resolving and clean.. but the Neco really steals the show, IMO.
My V.3 has the 8610s & lithium battery.. and boy, does the HD580 love it. A DEAD silent background, fantastic dynamic range.. and the artful Sennheiser sound.. on steroids! Treble has spectacular air, crispness, and detail.. the mids are very very transparent and deep.. with the bass coming tight and punchy. One thing I've really noticed the Senn benefits from is the V.3's dual opamp setup.. which provide fantastic channel separation, imaging, and soundstage. It's so immersive.. I can listen to this setup for hours on end. I like this little combo more than my desktop rig (via the tube or SS output!) and the ODAC+O2 (which is a little too clinical). For those one the fence about this amp.. stop waffling.. it's a GEM.
I also dropped the gain jumpers in so I've got it set at low gain (2.3x) since it's being used with the ODAC (2 Vrms output). the Neco it quite ably drives the HE-500, btw. Very clean & dynamic, again.

When driving the HE-500.. I like this combo more than the O2."

The Odac USB DAC can interwork with an Android powered smartphone Samsung Galaxy S III as well as with a PC or a Mac.

Apparently "Galaxy S III + (some) USB DAC" and "(some) computer + (some) USB DAC" have at least the same sound quality:

"How about the SQ of the S3 + NuForce Icon HDP? What headphones do you use?"

"It's quite good. Slightly, not very noticeable, better than it was connected to my computer.
So if you wanna know more about this, you can just simply refer to those review of HDP.
P.S. I am using HD600 & UM1 for testing"
Wolfson DAC confirmed for Galaxy S3!

"For anyone interested, the D12 USB DAC works when connected to a Galaxy S3. It sounds the same to me as it does when connected to a computer."

A custom Nexus 7 interworks with a standard USB DAC FiiO E10 (that doesn’t work with stock Samsung Galaxy S III for the time being):

"Code:
pcm.usbdac {
type hw;
card Audio;
}
ctl.usbdac {
type hw;
card Audio;
}
pcm.!default usbdac

Back up your asound.conf and add this (or for simplicity sake, replace it with this)

This allows me to use my Nexus 7 to play over my Fiio E10 USB DAC, N7 + E10 + HD380 == fun.

It's too late for me to work on combining this with the stock asound.conf.

It's in /etc/ on stock rom and works once replaced."

"We are lucky, no such file or luck on GN or SGS3 yet, need to first understand how alsa works on those phones.

Yes, double check you need the alteration.
I never got sounds out the USB DAC without it.
And now with it, plays fine with DAC, but also when DAC is not plugged, plays sounds as if I never changed anything.
Which is nice either way, not needing to change the file all the time.
Need to find out if/how I can modify the default device for np and sgs3 now, they neither had nor sorry the file.
No support meaning adding the file doesn't change anything there."
