Summary: When my 10 year old Yamaha receiver went out, I began to look for something to power my 5 speaker, Polk Audio surround system. I also needed a receiver that could power my bedroom speakers separately and not break the bank. Not easy to find.
Summary: This product is everything it is advertised to be. This is my first Onkyo product purchased. It is a great quality receiver for a reasonable price. It has more than enough inputs for a variety of sources. I would purchase Onkyo products again. Amazon was fast and easy for shipping.
Summary: I was in a jam for a way to get 'digital coax' to a set of speakers because the new TVs don't have the Dolby decoder or the connections for 5.1 or surround sound. This was the perfect, inexpensive solution with great Onkyo quality.
Excerpt: The Onkyo TX-SR304 is an excellent entry level audio/video surround sound receiver that provides the audio quality of much higher priced systems without the high price. The sound and performance of this model are very good when compared to the competitors stacked right next to them.
Summary: Got this receiver because I wanted an inexpensive Amp/Receiver for my HDTV, BlueRay and Satellite Radio setup with 2 digital/optical inputs. Ended up returning it to Amazon (very easy; super customer service!)due to the annoying hum it puts out on my $200 speakers at low/no volume.
Summary: Fed ex dropped by today in a Budget rent a truck and I thought...OH NO!...some unshaven goofball who was hired by Fed-ex because of the holiday overload dropping off my BRAND NEW ONKYO SURROUND SOUND RECIEVER, and I just hope it hasn't been THRASHED!..
Summary: We actually purchased 2 Onkyo TX-SR304B receivers about three weeks ago from Amazon at a surprisingly good price. We're using one Onkyo in our living room and one in the bedroom to enhance the sound from our new HD Samsung TVs.  The dark black receiver looks great.
Great receiver plenty of power and awesome sound quality

Summary: This receiver really packs a punch for the money and features it offers. Plenty of power sounds just as loud as some receivers that claim 100 watts/ch. This is due to Onkyo rating there systems 20hz-20khz vs the 1 khz that most other companies rate on plus Onkyo rates there power usually lower than...
Summary: I bought an Onkyo TX-SR304 in April 2007. It was fine while it worked. It failed in November. I dropped it off at Allen's Inc, the authorized repair facility in San Diego on 12/3. As of 1/17/08 Allen's says it has not diagnosed the problem. Onkyo does not answer the phone or email.
