I've found the converse true as well. Some ECM albums are available on Qobuz or Gube in high-res but on HDTracks only 16/44. Terje Rypdal's Odyssey is available in the following resolutions through various vendors: 16/44, 24/48, 24/88, and 24/96. I contacted ECM but they did not reply (surprise). Can there possibly be 4 versions of this one album? More likely it's not correctly listed. I'm so confused.
