AUDIOTRAK imAmp Portable Headphone Amplifier

VictorHalgaard

WARNING: BAD TRADER
Also known as HeadphoneViking.
Pros: Can power anything you throw at it! Neutral and pleasant sound. High built quality.
Cons: Not a very practical shape
So, what is this strange looking thing? Its a headphone amp in a personality crisis, thats what it is! It wants to be portable, but have the abilities of a desktop amp, it wants to be cheap'n'chinese but at the same time have the build quality of a shoe made by some italian bloke with too much money and leather.
You might think this is deemed to be a failure before it has even been made, but no! Its not...Though it has a few impracticalities, or well, one really, and that is the shape of it, it is allmost double the width of a normal portable amp which personally made me make a leather carry case with belt straps because it is just not "pocket-able". 
Now, enough picking on the fat asian kid! (amp)...Lets see what this is good at. The design looks very nice with the black aluminum, gold writing, blue on/off led and rubberized volume knob. 
What this amp is in reality is a desktop am with a rechargeable battery. That results in only 8 hours of usage pr. charge but for most people that should be enough. I will play while it charges so that wont be a problem. It has (all goldplated) RCA and 3,5mm jack inputs and both a 3,5mm and 6,5mm out.
It has been able to drive everything I've used with it so eardrum-shredding levels but with a sound quality and clarity i have rarely found with anything else than amps that cost on the unpleasant side of 200$.
So if you have a crappy source or some headphones that are hard to drive or for other reasons need amplification or cleaner sound then this will be a very good choice if you haven't just won the lottery.
