SoundPath Lab currently tracks 13 Questyle products, including CMA desktop systems and M/Sigma portable products. The historical questyle.com main domain returned an expired-site page during this review, while the Questyle-operated shop remained available. Until the main domain is restored, claims should be tied to a current product page, manual or archived source rather than the expired homepage.
Portable output and desktop amplifier claims remain source-labelled until the exact hardware, load and firmware are independently verified.
