This comes with USB and optical cables, two leather bags for holding the amp and topkit, the topkit with opamp rolling instructions, and the amp itself. It is currently configured with the EL8201 buffers, and AD8656 opamps in L/R. Battery still lasts a long time -- have no idea how long though, as I always listened with my computer and had the option to charge by USB if it ever went dead.
I believe I'm the 2nd owner for this one -- but still in great shape! It has the occasional nick, and the plastic is cracked in one place on the optical connection, but it doesn't affect anything other than looks (I received it in this condition).
