I have a blind test available to me with my own materials on my own rig, built right into my DAP. it's called the 'revealer' and it was provided as a firmware from pono. I don't bother posting "results" since A- they really don't prove anything I don't already know, and B- you wouldn't trust me/them if they did. I can close my eyes, run my fingers in a circle, and the ponoplayer will select 1 of 4-5 versions of the same exact 24bit source file encoded to various qualities, some lossless, some lossy. have you seen this? let me grab a screenshot from someone else: You have to set it up in the desktop client by feeding it 24bit files, then it will churn out 3-4 versions below what you give it, depending on where you start. Then you sync and the player has those songs set up in a separate area to play around with. you can close your eyes and blind test away. The playback mechanism stays in the same location when you select a different rez and almost gets to gapless switching, but not quite. I don't know what kind of volume matching they might have done, if any, but I know they used open source downsampling, dithering, and lossy compression techniques that are not deliberately old or flawed. I have read and posted with enough people inside that project to believe they aren't trying some VW crap on the files. Screenshot shows, from bottom to top: 192k MP3 - 256k AAC - 16/44 PCM Lossless - 24/96 PCM lossless - 24/192 PCM lossless. (I don't think it can include DSD, although the player can play them natively.) I have 5-6 songs in there. It's so obvious to me within seconds, almost every time, that I sit here using the internet to try and understand why people claim to not hear it. Granted I can't call exactly which one I'm on every time, but I immediately sense whether I am in the big room or the small room. Soon as there is a cymbal crash or hi hat roll or super complicated texture like layers of guitar distortion, then you know where you are. Bass guitar is a real good tell. If you hear it as a low stringed instrument with string sounds you are in hi-res. The mix and the timbre of the instruments, things like the solidness of the kick drum in that bass line, is another tell. Multi-part voice harmonies -- if you hear all the voices come in and layer, not gel into one glob, it's lossless. If you hear breath and lip smacks, it's hi-res. I hear digital artifacts and narrow room in the red. I hear wide open spaces and accurate instrument blends in the green and yellow. Blue usually confuses me b/c it's so good and so bad, depending on which direction you are coming from! After lossy, CD sounds amazing. After hi-res, CD sounds flat and lifeless.
