Setup like prior Integra products, is relatively easy when using the updated graphical user interface (GUI). The DTR-8.9 walks you through the speaker setup, configuring speaker size, distance, and suggested crossover frequencies (independently adjustable in increments of 40/45/50/55/60/70/80/90/100/11/120/130/150/200 Hz). Then the Audyssey interface takes over, with an updated GUI that asks you to set the supplied calibration microphone in up to six seating locations before crunching the numbers. The default Audyssey setting is Dynamic EQ, which makes real-time adjustments that are intended to compensate for reduced audibility and balance between front and surround channels, particularly at lower volume levels.
Other options include Dynamic Volume (which adjusts output gain to maintain a static volume regardless of changes to input signal strength, Flat, Off, and MultEQ, which is the basic Audyssey curve (with a slight high-end roll-off similar in concept to that of THX's Re-EQ feature). Tweakers can choose to manually configure a supplied multi-band equalizer, but given the robust Audyssey processing that works in both frequency and time domains, I'd leave the EQ'ing to Audyssey.
The Integra played well with all my other components, and did not have any sync or lock on issues (which given the state of HDMI these days should not be taken for granted). Also noticeable was that, while Onkyo/Integra products tend to run hot, the DTR-8.9 seemed noticeably cooler than prior models that I'd reviewed (both running 4 ohm and 8 ohm speakers).
