Plinius CD Dilemma...

So this is the situation, I bought a secondhand Plinius 9200 after auditioning it first! The gentleman I bought this from use’s Totem Hawk speakers, Plinius CD101, and this amp.

When he span a disc on the CD101, I thought Wow and sat there for about half an hour, and was amazed by the what I was hearing!.

If I don’t wish to go for a CD101, what alternative I could use? Maybe DAC to match the Plinius CD player or even better it so I cause plug in other sources?

Budget’s upto £2k. I can pick up a CD101 for under that.
