No, Tidal HiFi does not use MQA. Tidal HiFi uses the FLAC (Free Lossless Audio Codec) format, which is a lossless audio format that preserves all of the original audio information in the music recording.
Tidal Master, on the other hand, uses the MQA (Master Quality Authenticated) format. MQA is a lossy audio format, but it is designed to provide a more accurate representation of the original audio recording than lossy formats such as MP3 and AAC.
Tidal offers both HiFi and Master tiers, but they are two different products with different audio quality and features.
Tidal HiFi is a good choice for most listeners, as it offers excellent sound quality at a reasonable price. Tidal Master is a good choice for audiophiles who have high-end audio equipment and are looking for the best possible sound quality.
Here is a table that compares Tidal HiFi and Tidal Master:
| Feature | Tidal HiFi | Tidal Master |
|---|---|---|
| Audio quality | Lossless CD quality (16-bit/44.1kHz) | High-resolution audio up to 24-bit/192kHz |
| Audio format | FLAC | MQA |
| Exclusive content | None | Yes |
| Price | $9.99/month | $19.99/month |
Ultimately, the decision of which tier is right for you is a personal one. There is no right or wrong answer. It depends on your needs and preferences.
