I have built a home Theater on a budget using a projector, and with a 120 inch screen, I wanted to upgrade the sound. At first I had an old Pioneer vsx-514 5.1 which was okay but not enough. I then purchased a Yamaha RX-V665 which did sound a lot better than the old Pioneer but still wasn't powerfull enough. I Had to turn the Yamaha and the Pioneer almost all the way up and the bass was weak and muddy. I still wasn't satisfied so I returned the Yamaha and asked the salesman which is your favorite receiver and he said Onkyo. Well I picked it up and noticed how heavy and ugly it was. The salesman told me it had discreet outputs and a massive high current transformer which means it will sound really good and powerfull. So I purchased this receiver, hooked it up, and listened to every song in my ipod and noticed a Huge difference in the bass response. It's so much cleaner and more powerfull I couldn't beleive my ears. The treble is also much cleaner. With the Yamaha and Pioneer I Had to turn the treble and bass all the way up. The Onkyo I have the bass only on 4 and the treble on 6 and it goes all the way to 10 leaving the previous receivers in the dust. The movies sound amazing too and dont fatigue your ears. The Onkyos Volume will go to 80 and I never have to crank it over 50 and plays all my huge speakers fine. I have all the speakers set to large except the small surrounds in the rear pushing 5 12's and the subs in the closet are 12's too for a total of 7 twelves in my home theater and dag does it sound good. The movies did sound a little harsh and bright at first, although after running the audessy setup and turning on the cinemafilter this thing brings the movies to life with a warm powerfull distortion free sound. The onscreen menus make everything very easy to setup. I am very pleased with this receiver, so go buy one! You will love it!

I went through 3 receivers in about 6 months: one blew a fuse, one would turn itself off if the volume was too loud (which I didn't think it was at all and initially attributed this more to older electrical circuitry in the apartment), and one sounded terrible for my component speakers...finally I settled on the Onkyo. The only reason I didn't go for it earlier was because it was about 100-150 bucks over my initial budget, but after all my problems, I knew my penny-pinching was costing me in the long run. The receiver is fantastic! The sound coming out of all speakers (especially the rear ones) have never sounded better. The different sound fields also sound great: I use the "sports" field for basketball games, "movies" for films, and so on. Compared to the other Pioneer and Yamaha receivers, this one blows them out of the water. Hard to run out of inputs, wattage, and volume (With this receiver, I can really blast it high...maybe it's not the circuitry after all) with this receiver. Perhaps the only downside is the remote. I only use the remote for the receiver, but somehow I can't turn off the receiver without pushing the "receiver" button on the remote first, even though it's already been selected. A small quip, not enough to ruin the overall taste. I forgot that my parents have this same exact receiver and it sounds great at their house so I do have multiple success stories with this receiver. It is a solid mid-price range receiver. The professional reviews for this Onkyo don't lie...pick this receiver up if you're looking for a solid bang-for-the-buck value

This replaced a 6 year old Sony receiver. This unit has lots of HDMI inputs and a mind boggling array of listening modes. It took a while to understand how listening modes are setup, but everything sounds great now. I haven't tried any video upconversion because everything is just passing through HDMI right now, but someday I might get around to hooking up the Wii to see how it works. I notice that I hear more surround sound on my DirecTV then I did with the old receiver, so I'm happy with it. Yes, this unit does run hot, so be sure to allow space above for ventilation. It says right on the unit that this is normal. The setup for surround sound is simple, you plug in a mic and position it in 3 spots in the room and it runs a setup program. I like this receiver and recommend it.

In the course of buying a new TV (a Samsung 7 Series 55'' LED) I decided to upgrade my receiver as well. I had a nice Technics reciever for a few years, but it was not anything to the level of the new flat panel and the bose speakers that I use. The Onkyo TX-607 is. Without a doubt, this unit delivers crisp, clear and powerful sound with a giant array of sound variations that can be used depending on your movies, music or gaming tastes. First class all the way and for me, $499 for an Onkyo that delivers like this is a great price. As well, I will be adding two rear speakers and moving to 7.1 shortly and this is ready to go (can actually add 2 front-high speakers as well, though I think that's overkill). Can't be beat! The room set up mic was an invaluable piece of equipment that comes with this and helped perfectly balance the sound in my bonus room.

Bought this after my 10 year old Sony was going bad. Love all the HDMI inputs. Picture from blue-ray is beautiful, the sound is incredible, talk about a difference.
