Or you could join the world in 2020, and realize that what was true in 1992, when flash memory was $100/megabyte, ram was $30-40/megabyte, and a good DSP was at least $20-30 is not the same world as today, when I can get all that for a couple dollars in reasonable volume, and it is more than enough to handle enough pre-buffering to never run out due to minor speed fluctuations from the transport, and would do so at far less power (i.e noise), than even the ECC chips in late 80's, early 90's gen processors.
Some people are lost in the forest, and are quite happy to be there. Problem is, they want to drag other people into the forest with them.
Stereo5, most likely is that Esoteric sounds the way you like. Not technically better than another DAC, but sounds the way you like. Playing off a local SSD or memory card offers the potential for far lower noise than the electronics required to run a CD transport and error correction/interpolation. Rip your CDs to storage, and many programs will tell you exactly how many uncorrectable errors there are (if any). Many will even take multiple passes in an attempt to get an error free read. Everything is done "offline" so any transport or other issues disappear. At that point, it really comes down to the DAC, and if integrated, you pretty much eliminate any jitter from an optical or electrical interface.
