Classé Audio Delta Mono - Power Amplifier

Description

The Delta Mono is Classé's monoblock power amplifier, delivering exceptional performance and durability through hand-selected components and a fully balanced circuit design. The first 35W run in pure Class A, with over 300W per unit total (1,000W into 2Ω) and proprietary ICTunnel cooling technology that makes it uniquely stackable and rackable.
