Highly regarded Classe' sound at a fraction of the price. Monoblocks have balanced and single ended inputs and can be bi-wired. These were used to drive rear channels in a home theater, but are killer amps that can be used for 2-channel systems as well. Consolidating components to save space with room downsize. Kept in non-smoking, adult only household. Rated 8/10 due to age, visually look great. Original box and owner's manual included.
