Best Dac for a Shanling and squeezebox?

I've always been of the belief that it was better to spend more on a CD player than a separate Dac with an inferior player.
But with the advance of streamed hi res music I find myself wanting to invest in a Dac.

I have a modded Shanling CDT100 and have just bought a Logitech sqeezebox duet.They are running through a CAT SL1 preamp,Spectron power amp and Von Schweikert VR 4's.

As I havent a clue about current Dac performance what would you guys recommend that the Shanling and Squeezebox would run through. Budget up to $3000.
