Thanks for including Blu-ray Live Concerts and PureAudio High Fidelity in your list of Hi Res Audio sources. The hi res content on Blu-ray is encrypted for security, the only way to gain access to these soundtracks is via HDMI with HDCP, you have to have a downstream component with the de-cryption keys which the source device and component authenticate as a secure connection. Since none of the other sources of hi res audio are protected by the same encryption / decryption security protocol, its smart to by skeptical of the provenance, many downloads are merely upsampled verions of the CD, not truly native high res with no compression at 24/96K as found on Blu-ray. Even some of the Blu-ray releases, like Becks latest, include some MP3 tracks. Although these soundtracks are stored on Blu-ray compressed as Dolby TrueHD or DTS Master HD files, music sounds best without the post processing used for movies, choose LPCM playback instead to hear the actual original master recording. The emotional intimacy of seeing and hearing your favorite artists at their craft delivers a sensory experience that audiophiles have dreamed about all their lives.
"Pure Audio Blu-ray combines the Blu-ray format's vast storage capacity and bandwidth necessary for high resolution sound (up to 192 kHz/24Bit) in surround and stereo with the easy and straight-forward handling of a CD – on every Blu-ray player" Sound & Vision May 2016
Also it's worth noting that downloads aren't the only way to get hi-res music in your home. Some optical disc formats also carry hi-res and remain a viable option. I mentioned SACDs earlier, which remain widely available for delivering both stereo and multichannel DSD audio to a compatible player. And Blu-ray music and concert discs are also available at 96/24 resolution or better, typically as PCM or with DTS HD-Master or Dolby TrueHD lossless encoding. AcousticSounds.com, mentioned below, is a good source. You'll also find a wide range of concert Blu-rays at ConcertsOnDVD.com, and a list of labels and titles using the PureAudio Blu-ray format.
