Streaming resolution

I  listen to Tidal, at MAX resolution is way higher then what you claim is better sounding at a lower rez output, I think If your not hearing the better sounding rez than maybe its time to look at your digital streamer or DAC or music player, because what i'm experiencing using a decent DAC (Oppo 105D) with a outstanding streamer (Aurender X100) is nothing short of digital bliss, it blows me away at how much better digital music (done right) sounds soooo much better now then 10-20 years ago.

there are some excellent digital gear designers that believe roughly 4x the standard redbook rate (24/176-196 khz) is an ideal sample rate to make commonly deployed pcm digital filtering and reconstruction the easiest and most natural sounding....  all else being equal of course, which it never is...

@mattmiller its not that I’m not hearing the difference, but what I hear is as I said flat and too sanitary.  The edge is gone.  Don’t know how else to describe it.  I like what I have not looking to upgrade but just found that the lower resolution sounds more appealing.  Maybe it’s digital ear from CD listening and used to that sound. 

Like most things audio, my response to the sample/bitrate question is "it depends".

OP, in my view, resolution preference is real, but what's actually driving your experience deserves scrutiny. There's a good video on this which essentially argues:

Higher sample rates expose weaknesses in a DAC's implementation and analog output stage — what sounds "sterile" at 96/192 may reflect one's chain's vulnerabilities, not resolution itself. 

More fundamentally, the mastering matters far more than the format. A brilliantly engineered 16/44.1 recording routinely outperforms a poorly mastered high-res file. 

Also worth noting: most modern delta-sigma DACs internally upsample PCM anyway, which means the format battle is often already decided inside the DAC itself.

Overall, your sweet spot at 48kHz may simply be where your system is most forgiving — not where resolution peaks.
