About this gear
The HSA-1b is a purpose-built amplifier designed to properly drive RAAL-requisite's ribbon-driver headphones, which present an extremely low impedance load that conventional headphone amps can't handle correctly. It delivers the current-based drive these ribbons need for their signature speed and micro-detail, making it the reference partner for models like MAGNA and IMMANIS rather than a general-purpose headphone amp.
