9.2-channel AV receiver with superior three-dimensional sound field playback and the latest, most advanced Surround:AI features. Also with the latest Dolby Atmos. Link to all the spec's and info you may need. https://au.yamaha.com/en/products/audio_visual/av_receivers_amps/rx-v2085/index.html. I bought this from Harvey Norman about 5 years back. Unbelievable sub. I personally just love the sound of Yamaha. I have owned Yamaha receivers for the most part of 35 years. I love there natural sound. I have tried a few other brands but nothing compares. My opinion. The Onkya RZ50 came close. In fact, I used one that is now listed on trademe for a while, but landed up going back to Yamaha. I now run my system off a Yamaha CX-A5100 Processor. The only reason I upgraded from the 2085 is for more channels. I could only run a 5.2.4 with the 2085, where now the 5100, I am running a 7.2.4. that is the only reason I am getting rid of the 2085. Awesome receiver. Please check out my other listings. Have the origanal packaging so happy to ship at the buyers risk and expense.
