I wanted to play with ChatAI here's a bit of what it came up with.
Does a person need a MQA compatible DAC in order to play higher than 44.1k resolution files from Tidal?
No, you do not necessarily need an MQA compatible DAC to play higher than 44.1k resolution files from Tidal. Tidal streams high-resolution audio files in two different formats: FLAC (Free Lossless Audio Codec) and MQA (Master Quality Authenticated). If you have a standard high-resolution DAC that supports FLAC up to 192kHz/24 bit or higher, you can stream and play Tidal's high-resolution FLAC files without any issues. However, if you want to stream Tidal's MQA files and decode them to their full resolution, then you will need an MQA compatible DAC. An MQA compatible DAC is able to fully decode the MQA files and restore the original studio-quality sound. Without an MQA compatible DAC, you can still stream and play Tidal's MQA files, but they will be downsampled to a lower resolution.
What is the difference between Tidal's hi fi tier and the Master tier?
Tidal offers two tiers of subscription services: HiFi and Masters. The HiFi tier offers users access to Tidal's library of high fidelity (hi-fi) music in CD-quality, which is 16-bit/44.1 kHz. HiFi also offers access to exclusive content, music videos, and editorial editorial content. The Masters tier, on the other hand, offers a higher quality of music playback than HiFi. Masters is based on the industry-standard MQA (Master Quality Authenticated) technology, which enables high-resolution streaming of studio-quality music files. With Masters, Tidal streams music in 24-bit/96 kHz or 24-bit/192 kHz (depending on the availability), providing an even higher level of sound quality. The difference between these two tiers of subscription lies solely in the quality of music playback. HiFi tier offers CD-quality streaming, while Masters offers higher-resolution 24-bit streaming.
So if I am a Master tier subscriber from Tidal I can play 192k files without a MQA compatible DAC?
Yes, if you are a Tidal Master tier subscriber, you can play 192k files without an MQA compatible DAC. Tidal uses two types of audio formats for its Master tier - MQA and non-MQA. Non-MQA files are hi-res audio files that are encoded in the FLAC format with a sampling rate of either 96kHz/24 bit or 192kHz/24 bit. These files can be played back by any compatible audio endpoint or DAC. MQA-encoded files are also 96kHz/24 bit or 192kHz/24 bit, but they are packed in a way that allows them to be streamed in smaller file sizes. In order to unfold the MQA-encoded audio, you need an MQA-compatible DAC, which can decode and interpolate it into a higher resolution audio signal. However, even without an MQA-compatible DAC, Tidal will still stream the audio at a 96kHz/24 bit or 192kHz/24 bit resolution.
According to this if MQA goes under Tidal will be fine. Well, I guess as long as Tidal has duplicate HR & MQA for all available albums where MQA is offered.
If your DAC does not support MQA, you will not be able to fully decode and play MQA encoded tracks on Tidal at the highest resolution. However, Tidal offers high-res streaming without MQA, so you can still listen to music at resolutions higher than 44.1kHz.
I would like to add that MQA is not the only way to get high resolution audio from Tidal, and many DACs support high resolution audio without the need for MQA decoding. In addition, Tidal offers multiple streaming options, including FLAC and AAC, which deliver high-resolution audio in a variety of resolutions.
You were spot on
