Your British IPTV plays MQA audio files as regular FLAC, losing the authentication and unfolding. Your IPTV reseller's British IPTV panel doesn't support MQA decoding, and their IPTV panel treats MQA as standard audio. The pattern that keeps showing up across British IPTV MQA complaints is this: an IPTV reseller using a cheap IPTV reseller panel has no MQA support. A British IPTV reseller with a professional IPTV panel supports MQA decoding or passthrough. A real-world example: a user's British IPTV MQA files played without the high-res unfolding. His IPTV reseller said "MQA isn't supported." That said, ask your British IPTV seller: "Does your IPTV panel support MQA decoding?" An audiophile IPTV reseller will explain their MQA handling. Quick practical breakdown: an MQA-capable IPTV panel decodes or passes through MQA. Test with MQA content during trial. In most cases, the British IPTV reseller whose MQA sounds correct supports it; the one with regular quality doesn't. Honestly, hearing MQA files without unfolding on British IPTV defeated their purpose. The IPTV reseller's IPTV panel couldn't authenticate master quality.
