CompareCyrus soundKey vs Topping LA90

soundKey is an award-winning revolution in mobile music. Hi-Fi streaming services like TIDAL mean fantastic quality is available to subscribers, but phones lack the necessary hardware to get the best from this data. soundKey unlocks that data, using our years of expertise in high-resolution DAC and amplifier design. Cyrus quality audio is now available to everyone.

The TOPPING LA90 is breaking new ground. With near-perfect square wave performance and the lowest noise performance of existing power amplifiers, it reaches a new level of accuracy and performance that will leave you speechless.
