I bought this couple weeks ago but finally found it's too big for my desk. This one have very good review from head-fi and ASR. I paired it with my hd800 with good result, a bit warm sound with good sound stage.

I'm asking for $360 net, buyer pays shipping fee and paypal fee if there is any(F&F is welcome). Thanks.

This is the unit which is measured by amir from ASR so the performance is verified.
It's a relay based volume control, you can hear clicking noise when adjusting the volume, also the clicking sound won't stop at some positions, you need to turn the knob a bit to stop the sound, this is not an issue, it's from the design.
