One of the key points about higher sampling rates/bit depths "overtaxing" processors is hopelessly out of date. There is no such problem today. Some recording companies routinely use 384k or higher PCM sampling or double DSD sampling, or even higher than those. Home equipment for playback also exists. My DAC handles 384k/quadruple DSD with no problems from my PC.
My PC routinely plays 6 or 8 channel recordings from my NAS at 192k or from DSD converted to 176k, while simultaneously performing DSP processing for bass management and complex Dirac Live room EQ. It does that without any degradation whatsoever even while independent processing tasks are running simultaneously. The PC itself is a stock Windows PC using an I7 processor, which cost under $1,000.
Yes, there are rapidly dimishing returns and vanishingly small sonic advantages from ever higher sampling rates/bit depths. But, hi rez sounds noticeably better than standard 44k/16. Even 48k/24 does. One main advantage is greater freedom from time domain artifacts in the reconstruction filter for PCM as it is pushed up further in frequency into inaudibility, and DSD also avoids that by its very nature. Added bit depth audibly improves low level detail, such as reverberation tails.
So, one can go crazy with resolution numbers. But, single DSD or 88k or 96k PCM are very worthwhile over 44/16.
