I bought this a couple of weeks ago, for £185. Although it is very good, my hearing isn't really good enough to get the most from it. 
I have found that it is essential for my iPod Nano, if I wish to use my Sennheiser HD580s, but my 5th gen Video drives them well. The bass response is excellent with really tight and natural sounding bass. The higher frequencies are handled excellently too.
The amplifier is in mint condition with a fresh PP3 battery, instruction/specification sheet, unused mains adaptor and iPod dock connector (high quality) with high quality cable and gold plated 3.5mm stereo plug.

I'm asking just £110 including RMSD. Paypal preferred +4% or gift please.
Thanks for loking.
Ian
