Classe Omega stereo and mono capable amplifier. Largest stereo amplifier made by Classe weighing 250lbs and almost 30 inches deep. It is a dual mono design and uses two power cords. 5KVA transformer for each channel so it doubles it's power rating into lower ohm loads, so 900wpc into 4 ohms and 1800wpc into 2 ohms. Working great and cosmetically good with just a few marks. Flight case for complete protection and I have a pallet to ship it on. About $500 to ship in US.
