Storm Audio’s latest integrated amp is the Ri70 Revelation (€4900). Power is 125Wpc, and the unit will accommodate three line-level sources plus one balanced via XLRs. The clean look offers few clues to the unit’s flexibility, such niceties as polarity inversion, a transformer decoupled from the chassis by a special inert material that absorbs vibrations, and the company’s StormFocus loudspeaker impedance matching.
