This is a tough post.. If you have tons of cds.. then you owe it to yourself to get a nicer player. One with a better d/a convertor... something more musical. The difference will be jaw dropping as you say.. I went from a Nice Classe cdp3 to a Krell kav 300 and it was even more dropping... simply stated, the da convertors in standard components and something as simple as a portable cd player, cannot compare to a nice solid state player with a heavy duty transport and class a electronics... detachable power cords for upgradability, digital and coax out for future dac upgrades... In short, it will be well worth your while...Cd is not going anywhere anytime soon.
Good luck,
Joe
