D-EJ615

The D-EJ615 looks like the best-furnished version within its family, not because the core machine was fundamentally different, but because the surrounding experience seems to have been more complete. The manuals point to a better-specified bundle around remote use and power, which matters in a line where shared hardware had become normal.

That makes the model useful in a very specific way. It shows how Sony could create hierarchy late in the portable CD era without needing a new chassis or a new playback concept. Packaging and included interaction were enough to move a player upward.

The D-EJ615 belongs to that fully mature phase of the line. It expresses difference through refinement of ownership rather than reinvention of the machine itself.
