This topic form is intended to uncover the truth about what Sonos products (if any) actually support Hi-Res audio (ex. 24bit/192KHz, DSD, MQA). Further more I would like to exclude personal opinions about PDM (pulse-density modulation) vs DSD (the format used by in SACD). Weather you can hear the difference between a 256k AAC version vs a uncompressed 24bit or DFS file is worthy discussion, but just not on this topic. Again I would really like to understand what Sonos is doing or planning to do to support Hi-Resolution audio. There is a flood of Hi-Res content being released from master studio recordings. This trend is on the rise.
