I upgraded the power cable ($60 used), digital cable ($70 used), and tube (Western Electric 396A $25).
To my ear, the tube upgrade brought more positive sound than the two cables combined. Now, it is not hard to notice that mhdt with my Marantz DR700 CD player sounds better than the CD player alone.
