Tri vista 21 vs Jolida jd 100

I am now tring to decide if a tube dac is the way to go. The only reason I might not consider the Dac is the room needed. I can not find all these components to listen to . My system is: Myryad cdp, parasound halo a23 amps, Parasound c2 , Adcom 850 dvd player and paradigm studio 40s speakers. Thanks for all you help..Joe
