  Well the C5 and iPhone 4S pair quite nicely with the Alpha Dog. Not bad. Not bad at all. The O2 just has a little more bass rumble next to the C5, and the previously mentioned larger soundstage and laid-back mids.

 
 
...and slightly more laid back treble as well.
In all, to my ears, a better sounding amp all around.

Yup that's an A/B/C/D-er. It's the FiiO HS2, but they no longer make it. I got it for ~$20 USD from a vendor and they sold out. You might be able to find one on eBay.

 
Not $20, but here ya go.  I was tempted, but seems you really want it, lusident.
 
LOL, seems there are two.

 
That's excellent.  I think I might still build my own for fun.  So I'll pass on that one, but it's good to know it might popup on ebay now and then.

One of "professional" reviewers on our local, Polish audio forum claims that this Fiio device interrupts the audio signal and thus it is actually useless for testing purposes; it's it not transparent/objective. For example for him some naturally worser headphones (in terms of technical capabilities) and the sound) sounded better from this Fiio device than other headphones which are naturally superior (in terms of technical capabilities and the sound); the same related to the amps. I was initially interested in this Fiio device but after this review I resigned from its purchase.
AFAIK the problem with this Fiio device was crosstalk.

I was worried about that, and are there any components inside other than a switch?  They could be altering impedance which could vary the sound of each headphone...  I'm going to build a simple switch with direct wiring to each input jack.  There will be nothing to degrade the sound.  No digital switch components or anything that could alter the signal.  Something like this:

When I used the HS2, I heard the same differences as I noted in my C5 review between it and the O2. Likewise for the C5 and E12.

Without using the switcher, although switching by hand takes a while, I noted the same differences when using the Alpha Dog.

Ha. I'm not that good. Im really just using the case to make an abx box to test different audio sources quickly. . Nothing as cool as a dac.
