SA-15S2 original cable is not bad, I suggest you change the fuse on power cable rather than change power cable, since I found change cable will have negative impact, which will affect it's sweet sound, so I'm still found what powe cord suit for this player.....
Try to put it on Musical Fidelity Stable-1 Table, you may found more significant improvment.
Thank You your suggestion, I will use the original power cable for this moment.
By your suggest change the fuse on power cable, I have a fuse from the group order are not used.
