Summary: I've owned this receiver for about a decade. I have pushed this unit to the max and it hasn't failed. For years I bridged the receiver (not recommended) and ran a pair of DCM 12". I have blown both of the speakers (cross overs) but the Onkyo remains strong. My first receiver was an Onkyo and it lasted even longer. Top quality, I don't know if they make them like this any more.
Summary: I've had this receiver for over a month. Hooked up to two Sony MB350 speakers the sound is awsome. It does have a loudness switch. Turn on the selective tone control and it gives real deep bass. I also love the tape monitor which enables me to monitor recording discs. The radio reception is also good. I use thick speaker wire as an antenna and it does the trick. I'm able to receive at least 20 stations. A great receiver! Way to go Onkyo!
Summary: I had put off transcribing my extensive vinyl collection to cd for a variety of reasons. But, a couple of months ago I decided to go ahead and start the project. I still had and was very happy with my mid seventies two channel system consisting of a HK730 Receiver, Akai GXC750D Cassette Deck, Dual 1246 Turntable and Wharfedale W90D speakers. I didn't have a CD recorder and I had been dissatisfied with the results of running my source into the sound card of my computer.
Summary: We're using this to go from PC audio card to speakers for a small gym. It works very well. Simple. Low price point. Reliable. Lacks the bells and whistles of a surround sound system, but works great for basic stereo needs
Summary: I previously owned Pioneer and Yamaha surround AV receiver at twice the price of the Onkyo TX-8511. Neither came close to the spacious and clear sound I get through the Onkyo. Since I primarily listen through headphones, I had no real use for multi channel monsters with all the fixings. I just wanted something to listen to my CD's and my DVD movies and I got plenty of bang for the buck with Onkyo. Easy hookup and fabulous sound.
Summary: I researched my receiver purchase for a 2X system with phono input and almost bought the Harmon Kardon, but got advice from friends that Onkyo was far more reliable. Although the lack of a subwoofer output necessitates more speaker cable, I am very happy the purchase. The overall sound quality and usability of this unit exceeds my expectations for the price. It is very heavy and solid and looks much better than the web photos indicate.
Summary: This receiver has been great! Wonderful sound quality, a phono input and plenty of power. Tuner works great. The button for tape deck on front says "Tape" as opposed to the usual "tape monitor" which my wife never understood. (It also has a tape monitor feature on tape2). Highly recommended. The only drawbacks: the display lighting is sickly green and doesn't look nice. Also, this receiver should have a loudness button. Other that those small points, I love it!
Summary: Looking for a great sounding two-channel stereo receiver at a reasonable price? I did a lot of research on receivers prior to deciding to go with the Onkyo TX8511. I found that the ratings all over the web for this unit were very good for a basic stereo receiver, I do agree. Features I wanted in a unit was, multi-zone, 2-channel stereo, phono hookup. It had to be a basic stereo system with good quality stereo sound.
Summary: This is a great buy and has really good sound quality. Above all, it works very well with my phonograph,tape deck, casette player, and two channel speakers, which I send to two rooms. It is hard to find a receiver that works now with older components. As one who has a vaste 33 rpm record collection, I am glad Onkyo has this product and is selling it for a reasonable price. Note:It does not have an equalizer.
Summary: The TX-8511 Onkyo Stereo Receiver is an affordable, efficient way to upgrade the quality of your sound system. This receiver even made my old set of speakers sound great. I recommend this receiver for people who just want the basics for their sound system. For me, it was important to have a phono input, because I listen to records. The TX-8511 has the phono input as well as inputs for anything else you might want to hook up (e.g., CD players, multiple tape decks, etc.).
