Class D gets style
Friday, April 29, 2022

Exclusively distributed in the UK by Henley Audio, the HiFi Rose RA180 integrated Class AD amplifier claims to combat the problems inherent with Class D by using a “Gallium Nitride FET instead of a Silicon FET to dramatically improve the ‘Dead Time’, which affects switching speed and accuracy”. This £5,499 amplifier boasts one of the most comprehensive feature-sets of any high-end amplifier, and serves as the ideal partner to its maker's music streamers.
