Advisement...

[speakerman39]

I just recently purchased an Onkyo 705 receiver. Yesterday, while watching a couple of movies I noticed that it sure got very hot. Heck, I did not even have it turned up that loud and was ONLY running a 2.1 set-up. My fronts are the Polk RTi6's and my sub is a Mirage Omni S10. I have owned many receivers but never had one to get that hot. I could not even imagine how hot it would get if I was playing it at reference levels. I also understand that there has been some heating issues with some of the Onkyo receivers but mostly on the 805, 875, and the 905. Has any other members here had the same problem with their 705? I plan on sending it back and exchanging it for a Yammie 663. Am I doing the right thing? Keep in mind that my new room is about 750 ft.^3 with a 7' flat ceiling. I will be running a full 7.1 set-up and do plan to get a BR player sometime in the very near future. My plan is to wait till the prices come down some more before buying one. Until then, I am using a Toshiba A-3 HD DVD player. Lastly, I also just ordered a LG 42" 1080p LCD-took the 32" 720p Vizio back this morning. Any advice would prove to be most helpful.

Oh, one more thing. I also noticed the Polk RTi6's were brighter sounding with the Onkyo 705-almost too bright for my tastes. In the past, most of the times I have gotten to hear the RTi speakers have been with Yamaha receivers. Hence, it did not sound quite as bright. Has any other members here noticed this as well? In other words, I am beginning to believe that the RTi series speakers sound better (not quite as bright) with a Yamaha receiver than with Onkyo. Of course, this could just be my imagination but noticed it just the same. Please feel free to comment.

I think exchanging it for a Yamaha would be a good idea. The Yamaha receivers tend to run on the warm to hot side as well, but nothing like you are describing. It seems as though the latest Onkyos are plagued with this problem.

One of my very first receivers was an Onkyo. It sounded so good but never seemed to get as hot as the 705 does. I did have a Pioneer 1015 that NEVER hardly even got warm even when cranking it up a bit. I want a Pioneer 1018 but am NOT going to wait several months to make my change. Looks like the 663 is my best option. I also at one time owned a Yammie RX-V650 and then later the 759. Was very impressed with the 650 BUT the 759 was a disappointment to say the least. It looks like the 663 is very similar to the 650. However, I am NOT dogging Onkyo but something is going on.

My first decent receiver was a Pioneer, and I liked it quite a bit, then I got a real receiver, a Yamaha RX-V1600 and recently stepped up to a RX-V1800 and couldn't be happier, they are so nice and built solid. The RX-V1800 gets warm just sitting there, but it doesn't have much breathing room above it, but it's not a concern for me since I'm only using it as a pre/pro. I think you will be very happy with the 663, I think that is what I'm going to get for my bedroom system once I can start saving up again.

Yeah thanks glock for the help. I agree that Yammie receivers are solidly built. Both the 1600 and the 1800 are in one word-AWESOME!!!!! I think the 663 will do me for now BUT chances are I will end up with a Pioneer 1018 once they come out. Do you think the 663 will have enough power for such a small room? I know the Pioneer 1018 would be. Just wished it was available now.

I've not looked at that Pioneer, what is it about it that you like? What does it offer that the current models of other makes of receivers doesn't have?

Oh, just loved my 1015 so much. I also like the looks better of the 1018. It is also has more power and will work fine with my Polk RTi series speakers. I just think the Onkyo is NOT the greatest match for the Polks. Others may feel differently.

Those Pioneers definitely are nice looking. I see in your first post you had a vizio tv, how did you like it? I'm eventually going to be in the market for a 37" - 46" tv for my bedroom, but don't want/need anything high end or expensive since it won't get that much use, and was considering the Vizio line, but haven't really looked at them too much.

The Vizio was decent. At times, the picture would amaze you but no sooner than you think that things would change. For one thing , there was a lot of "ghosting" and I could see the picture being overscanned if you will. Of course, I only have Insight Communications analog cable tv so really couldn't expect too much. When viewing a dvd on my Toshiba A-3 the picture was better. But even then, I would see some white spots bleeding into the picture. The blacks were not quite as deep as I like either. When watching an HD DVD things were just a frazzle better in that regard. The Vizio, however, did a better job picture wise via analog cable tv than my former 40" 768p Sony did. But, the Sony had a better picture when watching both regular dvds as well as hd dvds on my former Toshiba A-1. Thus, the blacks were also much deeper and just flat out looked better over all. For your needs though, I would think you would be happy with a Vizio-at least for the money.

Don't know about the heat issue but I seriously doubt that the receiver is what causing the perception of speaker brightness Not from those two brands. Unless there is a strange frequency response curve in that receiver, highly unlikely.

Most likely it was just perception that is not quite correct. Unless you compare them side by side, carefully, levels matched, bias controlled, who know what was real or not.

Biased? Are you kidding me? There are a large # of people who believe the Polk RTi series of speakers are "bright" sounding regardless. I have always thought and still do believe the RTis series speakers are naturally a bit forward sounding with a slightly bright and crisp presentation. As such, I like that sound and that is why I own them. I have on hundreds of occasions heard the RTi's on various receivers but as I mentioned earlier mostly on Yamaha equipment. All I am implying in this thread is that I noticed that the RTi speakers I own sound significantly brighter to the point of being somewhat harsh with the Onkyo receiver in that it may not be a good fit so to speak. Therefore, this is why I posted this thread to see if any other members out there had come to the same OR nearly the same conclusion. Personally, I believe my perceptions are intact BUT you are entitled to your opinion no pun intended. I am convinced that the RTi speakers sound brighter with the Onkyo 705 than they do with the Yamaha RX-V2800. The same holds true for the Pioneer 1015. These observations have taken place in the same exact sound room on many many occasions as well as in my own living-room. Like you, I am entitled to my opinion which may or may not hold any validity. This is why I posted this thread to ascertain if it is only MY perception.

 

[Hi Ho]

My Yamaha receiver actually runs quite a bit cooler when I watch movies or play music at reference level. When I watch TV at a more moderate level the temperature rises significantly but never alarmingly high.

Well, it matter not to me that you picked the Polk for being bright or no. But you are insisting that the Onkyo made it brighter versus your Yamaha. That is what I responded to and that is where your biases, subconscious that they are, is brought to be questioned and your perceptions of this.
You have no control over those biases that can very easily distort reality, no matter how many times you listened with it on other receivers. Unless the comparison was done better than what you seem to be implying, it is unreliable to that aspect. that is how bias works. that is why certain protocols are used when facts and reality are desired. Beyond that, it is really not that important, is it.

Hmmmm.........why do you suppose your Yammie runs warmer when watching tv then? Perhaps because most networks blast commercials...?????

It is okay to disagree w/me. Still not fully sure what you are implying other than you believe I am biased. Well, we all are to some extent. But, my biases are not directed to undercut Onkyo in any way shape or form. But rather just pointing out that,inmho, the Onkyo 705 receiver is NOT the best fit for the Polk RTi series speakers. Sorry if you feel as though my so called biases have no validity. What I am hoping is to get others to post their experiences with the RTi speakers and Onkyo receivers. Thank you for posting your opinions. Are there any others out there?

It's not watching TV that makes it hotter. It's the fact that I'm watching it at a lower volume. It's the same no matter what I'm doing. Higher volume = cooler temperature.
