More important than holding its value is.... your enjoyment and satisfaction while you have it. Doesn't matter if you "got a great deal" and it "holds its value" if you don't like it while you have it - or it doesn't match the rest of your system and priorities.
That said, I would suggest Musical Fidelity, Plinius, Rogue Chronus for value and sonics.
