LOL.. I think bhazard had all 3, or did.  Maybe he's sold off some of them by now.

  How do the KC06, Tenore and Havi perform for this amp?
Click to expand...

The swimming Donkey with my Tenore from Japan still hasn't brought it, otherwise the KC06, KC06A, Havi, and Dunu 2k all sound very, very good off my Nexus 5. Much better than without it.
 
The slight bass emphasis, clear mids, and slight treble boost works well, except for some tracks that have too much treble as it is.

  It's been over 3 weeks of daily usage, even leaving it on by accident for 8 hours at a time once, and I still haven't needed to charge it.
 
I usually have good intuition, and I figured this would be very close or better than the C&C which I feel is overpriced, and the NX1 shows why. It's not perfectly transparent, but it leaves $35 amps in the dust.
 
I almost jumped on the E12 $90 deal, but then I asked myself why? This thing does all that I need portable wise.

Plus the NX1 is much more portable being about 3cm shorter and 1cm narrower.

Yes, it's quite small, roughly the size of a credit card. (same as C&C BH)


Here's some photo's of NX1 with DX50 (the rig I'm using at the moment with H-300)







 
 
Brighter version for a size comparison next to iPod Touch 4G.

Is it exactly the same size as the colorfly c3?

Perfect! Might just be the portable solution fo me...

Not yet, though from a price to performance ratio it leaves BH2 behind no problem. I can say that with certainty.

I am more interested in technicalities. I am considering to buy something to use alongside E12, don't want to compromise too much on SQ.

@BenF

That's exactly my intended use as well (if I ever get it I'll let you know how it works).

Couldn't help but notice this thread, how good can this $40 headphone amp be? Well I checked out the photos for the Topping NX-1 board and it seems a bit fishy. The specs claim it uses a TI opa1611. The 1611 has 8 pins yes? So why does the chip on the board have 16 pins? It can't be a TI 1611. Anyone?
 

 
would it be more likely something like a TI614? don't know much about this stuff:)

I think maybe the TI1611 is the little tiny one up the top.

mmmmm, I count only 5 pins on that one and it seems to be on the USB power circuit.
 
Honestly, I am pretty sure this thing does not use a TI OPA1611 from the look of these pics.

Its possible that it is on other side of the PCB.
