To get good results with DIRAC you have to spend a lot of time with it, to make your speakers sound good! This program is definitely not very intuitive! Watch the Video from Gene at Audioholic and you will see what he says!
Fair enough, having multiple digital to analog conversion just muddy the waters, might as well stay in the digital domain until the signal is sent to the speakers!
I am trying out an NAD M33 and was wondering if I should use analog out from my CD player to the NAD or should I use coaxial cables? Also I have an older OPPO BDP-105 should I use the HDMi cable or the analog connections? It is just to listen to music
