Limits and unresolved details

Calibration inclusion is a manufacturer statement, not an SPL room-correction acceptance test.

Support and purchase checks

Confirm the complete regional model, required cables and external components, current manual/firmware, local warranty and actual dispatch with the official channel. App and streaming-service support depends on current versions; paid services may require subscriptions. A planned release or an order button does not prove local stock.

Keep an existing system that already meets these connection and use requirements. No measured sound-quality upgrade, reliability score or automatic purchase recommendation is assigned.
