Questyle Product

Questyle’s official SIGMA page is where you can verify the core specs I’m referencing: dual USB‑C, 3.5 and 4.4 outputs, and the Bluetooth feature set. This unit is basically the cleaned-up evolution of the CMA 18P—more focused, more portable, and with a far better wireless experience. I still want the engineers to add proper Bluetooth transport controls to make it a true home run.

Pros

+Clear official spec reference for ports, Bluetooth, and outputs
+Sigma is a refined successor concept: compact and purpose-built
+Line-out capability via 4.4 is useful for pro/mobile setups

Cons

-Current Bluetooth control implementation is missing key transport functions
-Windows use may require drivers (typical Windows behavior)
