ATI's AT1800 series amps are descended directly from the 1505 series amps, which were and are well regarded as bulletproof amps that exceed expectations at an excellent price. The AT1800 looks to continue the tradition. This series is more powerful per channel, and is configurable from 2-7 channels. Each chassis is loaded with two massive toroidal transformers in the power supply, so plug-in channel modules can be added to any existing unit, up to seven channels worth. Available now.
