The Heart of the M18i: Patented Current Mode Amplification

What truly sets Questyle apart is its Current Mode Amplification technology, a revolutionary approach to audio amplification that redefines performance and efficiency. Unlike traditional voltage-mode amplifiers, which are limited by high power consumption and distortion, Questyle’s Current Mode Amplifier consumes only one-tenth the power while delivering over 10 times the wide frequency range and ultra-low distortion of just 0.0003%. This means every note, every beat, and every nuance in your music is revealed with stunning clarity and precision.

The M18i takes this technology to the next level with its Global Patent "Current Mode" SiP Module, achieving an even lower distortion rate of 0.0002%. Whether you’re listening to a symphony orchestra, a rock concert, or your favorite podcast, the M18i ensures that every detail is preserved, creating an audio experience that is as close to the original recording as possible.
