Say hello to the Trinnov Optimizer. Nearly two years after it was first announced, the R-972 has arrived. After endless behind-the-scenes tweaking, this product will surely trigger debate and discussion among surround enthusiasts.
The beefy R-972 brings another round of rivalry between two major licensed technologies. Home theater buffs should be used to this by now. Trinnov’s debut sets the stage for a struggle with Audyssey for control of the auto setup and room correction technologies that are licensed to AVR manufacturers."
