I calibrated Dirac Live within an NAD M33 for a customer in Dorset. His system was the NAD Powering some Dali Epicon 2 speakers
The customer had just moved into a new home and was trying to make his HiFi system work in a new listening room, quite a large room. He has bought new speakers and several new amplifiers, he preferred the simplicity of the NAD M33 but was struggling with the overall tonality and shoutiness of the system at higher volumes. I used Dirac Live to tone down the shoutiness somewhat, improve the left to right imaging of the system and increase the bass for more 3D sound in the room. I was able to improve all aspects of the systems sound, without moving or touching anything.
