subjective matters,
please ignore if memory cards isn’t something in your priority. After all, they are used to store your music and play back. Just a storage medium.
Only read on if different type of tapes and vinyl weight or cables or everything will effect your sound quality and your are seeking for the best performances possible
Some more detailed comparisons between Sandisk Edge VS Micron 1TB
Capacity limits : Edges cap out at 400Gb VS Micron 1Tb
Signatures: Edges is more musical, Micron is more resolving. Edges textures is smoother vs Micron crispier
Edges is more forgivable on bad recordings, harsh distortions and clipping is easier to withstand, Micron will spit it in your ears and is very unforgiving but trade off for a lot more details that is easier to observe on Micron.
Conclusions: both Edges and Micron will bring the next improvements to the system overall with the improvements of
Better bass fidelity and articulations, more accurate density and overal presentations, larger soundstage in all axis, better clarity, better details and cleaner back ground, better dynamic
The differences signatures between Edges and Micron if can be elevated into DAP signatures would be Walkman (edges) vs Astel&Kern. If speaking about cables terms, Edges would be Silver/Gold alloys and Micron would be Ultra Pure Silver Litz. If speaking of simplistic terms, Edges is musical and Microns is resolving
If you ask me whether to upgrade your MicroSD or Cables ? I would opt for MicroSD every given chance , but why not both ?
