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

I have seen the 260D listed for $3000 and the 260Dt for $2000 not sure what you wanted to spend you gave no indication. The 260D has both xlr and rca out so it should connect to your integrated. Prices of cd players with dacs are all over the place. You just need to make sure whatever you get has a dac which most players listed as cd players do. This simaudio Moon is a bit confusing how they market it, I assume the little t means transport only. If it is listed as a cd transport you need to get a seperate dac to go with it. 

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

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!

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. 

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

@abstract; IMO your Plinius 9200 is a very nice integrated unit that you should keep, built like a tank and can drive any speaker. If you want to save space purchase a CDP (transport and DAC in one unit), there are many really good ones available new or used. There is nothing wrong with the Moon 260D although I have not researched the DAC that it has and possibly a different Transport and separate DAC would sound better, however not necessary.

ah...thank you both...reubent & twoleftears..Yes..that 260D is the model I am considering..I see that newer models of my integrated amp and (others) now have a DAC as part of their spec but mine now is before this new age...I plan to strictly listen to my CD's..not computer stream..so it looks like if I stick with this Moon I will need to get the Transport/DAC combo..(or upgrade to a more current Plinius integrated)..correct? (now I am just thinking outloud and hoping you are listening...thank you!

I can't find immediately the 260dt model you refer to, but I presume this is the 260D CD Transport with optional DAC.  As the name implies, this is something of a rare beast, in that the single box can be had either purely as a transport OR as a player (transport+DAC), thus obviating the need for a second box.

@abstract,

A CD player has 2 basic components/functions. It is a Transport (spinner) and a DAC (converts the digital bits read by the transport into an analog signal that can be input'd to your integrated amp.).

If you buy the Moon CD Transport, you will need a DAC to convert the digital output of the transport into an analog signal that can be sent via an analog interconnect cable to your integrated amplifier.
