This is why – for example – you never see YPAO making pin-point accurate changes with its PEQ system. What is more, using frequency-based corrections such as GEQ but especially PEQ can make these issues much worse affecting a system’s imaging. This is because phase and time-alignment issues caused by crossovers, room modes and first-order reflections will smear the original sound as it hits listener’s ears. However, correcting only the frequency response of a system won’t result in great sound. This can be something as simple as graphic EQ (GEQ) or something a little more sophisticated called a Parametric Equaliser (PEQ). Room correction started out at simply correcting for frequency response anomalies due to speaker and room interactions. Lastly, I have a few gripes with Dirac Live that I would like to see addressed before it takes over the world. I also rarely see reviewers fully understanding how to set up Audyssey correctly to level the playing field. I don’t see a lot of reviewers or sites fully explaining the pros and cons of each technology. Since more and more companies are switching to Dirac Live in their receivers – Onkyo and Pioneer being two of the latest ones to do so – I thought it would be important to compare Dirac to Audyssey and YPAO.
