I’ve been trying out Amazon Music Unlimited HD on the Node 2i because according to Amazon and Bluesound, BluOS supports Amazon Music’s version of High-Res (Amazon calls it HD for CD-quality 16/44.1, and UHD for anything greater than 16 bit-depth for sampling rates up to 192kHz). Have others tried it on their Nodes?
I’m getting one problem: any 24/44.1 files show up as 16/44.1 on an external DAC (RME ADI-2 DAC via Coax). Those same 24/44.1 songs streamed via Qobuz from the Node 2i show on the DAC as they should at 24/44.1.
This is not the case for anything higher in resolution from Amazon Music: 24/96 and 24/192 streamed through the Node 2i show on the external DAC as 24/96 and 24/192 (I couldn't find any 24/48kHz files on Amazon Music HD to test). So why does the DAC show Amazon songs labeled as 24bit/44.1kHz playing as 16 bit from the Node 2i, but the same songs from Qobuz stream through at the full 24 bits of dynamic range?
If you have an external DAC connected to a Node 2i that shows bit-depth and sampling rate for S/PDIF input (and have signed up for the free trial of Amazon Music Unlimited HD) please post here if you see the same thing.
The RME ADI-2 DAC manual, written by
@MC_RME says that if a 24bit song shows as 16bits then it is only 16bits. Maybe Amazon is padding zeros in the last 8 bits for 24/44.2 files only (since 24/96 and up is fine) and the RME is ignoring them; or maybe the Node 2i is doing something to the original 24/44.1 file.
