Question: how do i setup wi-fi with the tx-8020
Document: I was looking for a receiver to use with my HD TV.The Onkyo TX 8020 provided great sound at a decent priceusing 2 quality book shelve speakers.It was easy to setup, has necessary options without over doing it.I listen to Pandora thru Netflix on my HD TV and the sound is excellent.
I bought tx 8020 and a Onkyo CD player C7030. Detail is good. Separation Is also good. This combo is quiet. Therefore you should pair them with bright speakers. The display and print are  so small that it is hard to see.I think If you use this combo for the bedroom and you use the remote control, you will be fine. This combo is a step up from the mini system.
We bought this amplifier for use with a turntable to play our old vinyl records. Sound quality is very good, especially considering the price. As a bonus, the FM radio reception has been excellent. Setup was easy. This is my third Onkyo receiver and I have not been disappointed with any of them yet.
It sounds very similar to the old receiver it replaced, the only notable difference is in how the tone controls work.This has a "direct" control which cuts out the tone circuitry, the old one did not. Doesn't mean much to me in my setup but might beuseful if you are running a subwoofer and don't need any compensation for the mains as it offers less sound coloration.The old TX-8211 had Onkyo's infamous version of "loudness" compensation which stunk!
I have a simple stereo setup with two bookshelf speakers and a subwoofer. I have a phonograph and a ps3 hooked into the receiver and it's extremely simple to switch between inputs. Sounds great and is beautifully simple with only the features that I actually want or need. I appreciate the phono input and the subwoofer pre-out ports. If you want a simple two channel stereo system I recommend this receiver.
But again, have not hadthe opportunity to do such a hands on comparison.Also, I would not consider the older TX-8255 due to its older control design and the better remote features on the TX-8020.
[I don't understand this discrepancy because both receivers (unless I'm mistaken) are rated at 50w. ]In other words, for my set-up, the 8255 was far more efficient in powering my speaker/turntable combo. 25% of the volume on the 8255 (10 o'clock) was the equivlaent of 55% of the 8020 (40/73), in rough numbers.
3) It had to be affordable. The TX-8020 was the only receiver I found that met all three criteria. When I opened the box, I was surprised at how heavy and solid it felt. Hooking everything up was pretty straight forward and the sound is great. The remote is handy, too. I've been using it for about a week now and I'm very pleased with it.
So, the power is there... it's just released in (much) finer increments.There are no digital inputs or outputs on this unit. It's &#34;old school&#34;; folks who are looking for HDMI, optical, or other connections will want a different unit. An a/v receiver this is not.Likewise, folks looking to fill a large'ish room with ear-splitting volume levels would be disappointed in the TX-8020; it's not that powerful.
For reference sake, the volume dial on the 8255 starts at about 7 o'clock and ends at 5 turning the volume knob clockwise, as you would expect, from 7 to 5, softer to louder.Conversely, the new Onkyo 8020 lacks the direct 'keypad' input for FM, but far more importantly, seems underpowered. That volume had a digital read out, from 0-73 (or so).
Answer: The receiver is not a network receiver it is a plain stereo receiver, albeit a good one. If you wanted to receive streamed radio you would have to buy an external wi-fi device with a line level output that would feed into one of the unused line inputs on the tx-8020 i.e. TV, DVD, Tape.
