Arti, Tom is entirely correct. As to terminology, it's a stretch to refer to a mere player(rather than the CD or other data)as the "source", but this is part of the hype to justify spending absurd amounts.

Optical disc readers and the associated electronics(including the DAC)have long been at a stage of development where the digital content is extracted with noise and distortion far below audible levels and with audibly flat frequency response. Nothing more can be done, regardless of cost, and it's rare to even see the trouble taken anymore to test for the minute measurable differences in players.

Your present Sony, if still in good operating condition, is more than just "decent".
