Please help me figure out what I need to do this. My head spins with tech talk..

If you like the Plinius and are set on getting the Moon 260Dt transport ( I assume because you have found one at a very fair price) then all you would need to do to play via the Plinius is a very simple DAC.

Now if go this route you would need ensure the DAC you buy has the same input that the Moon has output, ie, spdif, toslink or aes/ebu.

Some of the cheaper DAC units are really meant for computer audio and come with just a Usb input which would not work for you.

Still I think there are plenty of sub $300 units that would work. A lot less than replacing the Plinius just to get a taste of transport to DAC to amp.

If you want recommendations for good low price DAC there will be no shortage of willing volunteers of information here.
Good luck

I am not sure which cd player you're looking at the Moon 260D comes with the DAC the Moon 260Dt is the transport section only. If you have priced the 260D then you're good to go. 

Correcting my mis-type..it was the 260DT that I was originally referring to..the transport only...I definitely want to keep my Plinius integrated ..so I guess I need to get the 260 DT and a good compatible DAC of which I will definitely need suggestions for, Get the 260 D, (will my 9200 plinius have the correct  inputs???),or look for a CD player only which seems to be slim pickings. I do find these journeys to be fun and hopefully ultimately satisfying. Thanks for your help!

If you got the 260d as opposed to 260dt you would be all set already, just plug and play with some half decent interconnect and you are good to go.
Depending on price difference between the 260d and dt that may be your best option.
Lets say you got 260dt and a dac and you do not like the sound, now you ask yourself, well was it the transport, the dac the interconnect etc etc.
Of course you still might not like the sound of the 260d but at least you eliminated one element.

I personally may lean towards the 260d
