Description
The STR Integrated Amplifier is Anthem's flagship two-channel component, combining a high-resolution preamp, a high-current amplifier section, and onboard Anthem Room Correction (ARC) in one Canadian-designed and crafted unit. It delivers up to 550W continuous per channel into 2 ohms, with MM/MC phono inputs, asynchronous USB audio up to 32-bit/384kHz and DSD, and flexible bass management for one or two subwoofers.
