About this collection
Questyle Audio was founded in Shenzhen, China, in December 2012 by Jason Wang, an engineer whose fascination with current-mode circuit design dated back to university research in 2006. Within eighteen months of launching the company, Wang had filed a global patent on Current Mode Amplification (CMA), an approach that amplifies current directly rather than voltage, the technique nearly every other amplifier on the market uses. It's a fundamentally different way of moving a signal, borrowed from high-speed communications engineering rather than traditional audio design, and it's been the technical backbone of every product Questyle has released since.
The company's first product, the CMA800i, established that approach at the high end of the desktop market, and the technology has since scaled down through the CMA line (CMA600i, CMA400i, CMA Twelve, CMA Fifteen) and into a run of genuinely well-regarded portable DAC/amp dongles, including the M12, M15, M15i, and the current M18i Max. All of it is manufactured through a partnership with Foxconn, giving a relatively small, engineering-driven company access to serious manufacturing precision.
The results have been recognized well beyond audiophile forums: more than 50 patents and over 20 international design and engineering awards, including the CES Innovation Award and the iF Industrial Design Award. What that translates to in the listening chair is a sound signature that leans analytical and fast rather than warm or forgiving, with very low distortion and a level of dynamic punch that outpaces the size of the devices producing it, especially in Questyle's portable lineup, where CMA technology normally reserved for full-size desktop gear gets packed into something that fits in a pocket.
