I stumbled across this new portable amplifier by TOPPING on eBay a few days ago called NX1.
I was wondering if anyone's tried the amp or purchased one yet?
It's stated to run for 100+ hours a charge and looks built pretty well.
If anyone's heard one yet please tell us about it.
Here's some photo's and specs from the listing.
Edit: (We were purchasing from eBay member tool_nerd except he put his price up by $100!. Thanks to member ebrian who did some searching we're now ordering the amp for only $36 from Deal Xtreme)

Topping NX1 measurements courtesy of Head-fi member Skamp.
I've always been curious to see how those "audiophile" portable amps actually performed. I also wanted a new toy to play with, and it was so cheap, I pulled the trigger and ordered the NX1, to measure it. Here are my results:
Output impedance: 0.15Ω
RMAA (unloaded): http://outpost.fr/rmaa/Topping_NX1.htm
RMAA loaded with Denon AH-D2000: http://outpost.fr/rmaa/Topping_NX1-Denon_AH-D2000.htm
RMAA loaded with Shure SE425: http://outpost.fr/rmaa/Topping_NX1-Shure_SE425.htm
Source for all RMAA measurements: EMU 0204 USB line-out
Basically, the NX1 performs very well, with near zero output impedance, high signal to noise ratio, ruler flat frequency response, no distortion to speak of, and high output. I have to admit, I'm very pleasantly surprised. I can't even hear any hiss with my Shures.
The picture doesn't quite convey how tiny that thing is.
Anyway, no need to get all lyrical, the amp's performance speaks for itself.
