If it still works, and you're happy with how it sounds, I'd leave it.
I have a Naim nDAC, with a Teddy Pardo XPS power supply, and it's easy to tell the difference from transport to transport. I use an Exposure 3010S2 CD player as the transport, and you can tell it's quite a bit better than the cheap Sony DVD player I have, and that it's not as good as a CEC TL3 (I think it was a TL3!).
I've also tried a Cambridge CXC, which was quite good, and an Audiolab 6000CDT, which was also quite good. Neither were as good as the Exposure - but then, the Exposure was something like $2395 new.
So if you want to try one, I'd say the Audiolab would be a great place to start. And there is always a rabbit hole to dive into!
