I calibrated Dirac Live within an Arcam AVR 850 AV Receiver with an Arcam P429 powering an 7.3.4 Dolby Atmos home cinema system with PMC speakers, PMC subwoofer and REL subwoofer for good measure. The customer also has an Auralic streamer with a musical fidelity DAC and quite a few other toys.
This was a repeat customer from a calibration I did on his AVR 550 AV Receiver and system about 2 years ago. He just upgraded to the AVR850 and hired me to calibrate his the system again. I have learnt a lot in the last two years and put that all to use here
I spent a large portion of time working on getting the system to sounds its best for stereo music, the customer likes music to sound a certain way and I worked hard to get the bass just right with a nice tonally saturated vocal with excellent soundstage.
I then spent time working on the system for home cinema performance and dialled that in to be optimal.
