I think that article is somewhat misleading. From my understanding, the main issue with standard bluetooth audio is that it was never intended to carry music. When creating a lossy codec, designers consider psychoacoustics to determine what information can be discarded during the compression without causing a noticeable drop in audio quality. The SBC codec was designed around making human voices intelligible, because it was initially intended only for phone calls, so it is badly designed to carry deep bass shimmering highs. At least, thats where I notice the most distortion.
By contrast, AAC, AptX and LDAC are designed to be as transparent as possible at a given bitrate for the whole frequency range. I don't know about AptX or LDAC, but AAC 256kbps is generally considered as good as MP3 320kbps. Bitrate is not the whole story. Codec design matters a lot.
I would reckon that AAC, AptX or LDAC if implemented well will be transparent enough for portable. Dac/amp quality in your bluetooth headphones is probably a bigger factor at that point. I wouldn't get too zoomed in on LDAC, AptX and AAC are pretty good and much more widely supported.
I'm new at implementing wireless/bluetooth audio. The only thing that really counts is how it sounds to the listener. Obviously there is a movement in the industry to improve the sound quality of wireless devices. LDAC is a problem because of it proprietary nature, but at this stage I need to listen to several types of wireless formats and decide for myself. I'll try the LDAC experience.........and yes I read there is some "reconstruction" of the audio here. I'm interested to hear how it sounds, especially compared to the wired option you have with Sony headphones. They also have noise cancelling, which adds another layer of processing. I'm not sure if that can be turned On/Off.
I will also use the R3 as a transport to an iFi iDSD micro to use as a DAC/headphone amp with a pair of Shure SRH1540s.
There will be lots of interesting combos to try with this amazing little R3!
