Home > Consumer Reviews > Onkyo TX-SR705 7.1 Channel Home Theater Receiver (Black)

I bought the TX-SR705 thinking it would convert my regular definition video from my DVD player and the low def channels from my cable to high definition. After trying to get it to work correctly for two weeks, I finally gave up and wrote to Onkyo tech support. What they said was that if I wanted to get the high definition feature, I needed to buy the SR875 or the next one above that (for $$$). I also had several issues with the lip sync changing from one day to the next. This was probably the biggest reason for returning the unit. I don't mind setting the lip sync once but having to change it every day is a pain.

On the plus side, the auto speaker setup was great and the surround sound (I have a 6.1 speaker setup) was great. Hopefully the Sony that I'm replacing the Onkyo with will be equally as good.

Bottom line: I know that a lot of reviewers ranked the SR705 very highly (that's one of the reasons I bought it) but I did not have a good experience with it.

I would have given this unit a 4.5 because it sound is powerful and has plenty of plugins for all of your components. The plugins aren't the easy wiring kind, but the biggest drawback is the manual is very difficult to follow and if you have to call the tech support expect to wait a long time to talk to someone. Once you do get someone, you have a 50/50 chance of getting someone that won't want to rush you off the phone. I had to call twice is how I came up with a 50/50 chance. It is a powerful receiver. But unless you are very good at setting up this equiptment, (I thought I was) you should get a surround sound in a box. it's already together, just plug and play.

Very prone to hum due to HDMI connections. With my old house wiring I didn't want to have all my equipment and the TV plugged into the same outlet but with this receiver such a setup can cause HDMI loops and will introduce ground loop hum. Supposedly the 805 doesn't have that problem but I would stay away from Onkyo products due to this problem.

I purchased this receiver 4 months ago. Started having some issues after a storm, mainly related to the remote control. After calling their customer service, I was told that I would have to ship the unit, and of course pay for it to a location in Corpus Christie, TX. (I live in Dallas)
They were not helpful at all to me in solving the problem which was under warranty.
Please think about it. Why would Onkyo choose a warranty repair facility in the farthest away location in Texas with a very small population when they could have chosen one with a much greater population concentration such as Dallas, Houston, etc..
I think they want you to not want to ship it, so basically NO WARRANTY!
Onkyo 705 may be a good enough product, but if you need their warranty, you are out of luck.

i bought this receiver a yr ago & it has already quit working (at the most inconvenient time**, i might ad) it has to be shipped off to houston to be repaired, a real headache. i've replaced it with a pioneer 7.1 receiver.
i'm 55 yrs old & i bought a pioneer receiver in 1974, a sony receiver in 1984, & a technics 5.1 receiver in 1998, & they all still work & are being used today. Thanks "onkyo" for bringing 38 years* of uninterrupted listening to a halt, & i'm sure pioneer thanks you for the sale also.
