I have a modded JD100 and it's my oldest piece. I also have a Krell SACD standard mk3 and a Don Allen Marantz changer. I have thought about the 5400ES often too. It does get raves. Most seem to really like it, but I did see where one audiophile said it sounded clinical in his setup and some others have sold theirs (like we all do). Whatever you buy to replace the Jolida will be a gamble as to whether it synergizes and matches well in your system to give you pleasurable sound. It's always, always about synergy. Let us know what you buy and how you like it. By the way, "for bass you can feel" I've read that the players with stronger bass performance will cost you several thousands more than your budget.
