This is a Sunfire Cinema Grand Bob Carver Signature Amplifier. It has 5 channels rated at 405 watts-per-channel RMS at 8 ohms, and 810 watts RMS at 4 ohms. For the left, right, and center channels, it has both voltage source speaker outputs for traditional drivers, and current source speaker outputs for electrostatic, planar magnetic, and ribbon tweeters. These dual outputs can also be used to bi-wire speakers, as outlined in the manual. The amplifier offers both balanced and RCA inputs. The top and sides of the unit have some scuffs and scratches, and a little bit of what appears to be paint residue. The front panel looks great; there is a couple small nicks on the top of the front panel, but it is in otherwise good condition.
