Did you use Dirac Live? I'm interested to know if you can use it as a one off to correct the eq and then stop your subscription? Or do you have to keep paying for Dirac in order to keep the eq settings?Good afternoon, today I installed an icon, before I had the node 130 and the difference in sound is noticeable in favor of the icon, using it through the DAC of my Copland CSA70 there is not that much difference, where the difference is noticeable and using the DAC of the icon itself, I just ordered the microphone to calibrate the Dirac, to me there is another improvement.
