I had the N05XD which was a streamer/DAC/Pre-amp. No interconnects needed. I swapped it out for a Reimyo 777 DAC, SPL Director Preamp and Lumin U2mini streamer. Then traded the XA25 for the SPL S1200. My system is now very accurate but the 777 made it holographic. I have to down sample all music to CD quality as the 777 doesn't not do any over sampling or hi-res music
