Yay!

Although the proof is in the pudding. You won't know for sure if they fixed the problem until it's actually plugged in and generating heat ... and lots of quality sound!

Selden, I lost it with that heat reference because it's so true. Now, My and Craig's schedule don't mesh for a while so it will be some time before I have it back in my system, but I am hoping for the best. But thanks for the laugh.

Is your room any cooler with the Emo amp?

You know Craig, I was thinking about that very thing last night. Even though I kept the door open, which helps keeps the room cool, it did seem not to get as warm in there. I even had some lights on and it wasn't that bad. Next time, I might close the door and see what happens. I don't know how powerful your amp is though. But it may be not quite as bad. But if I put my ceiling fan on, that helps. And my other fan really cools the room off a lot. But I am paying attention to that.

It's spec'd at 200 watts. Here's a review on it: https://www.audioholics.com/amplifie...pa-1-amplifier Page 4 has the measurements. It's 67% efficient. It never really got very hot when I was using it. Try listening to 2-channel with the 3-channel Bryston off and the door closed. See if that alleviates the heat issue. If so, we know what the major source of the heat is... and what the potential solution could be.

So If I notice a difference with the door closed (room seems cooler) when I do that, then we know that the 4b-ST is contributing to the heat in the room. Sometimes, with the door closed and even the ceiling fan on, the room does get warm enough for me to sweat. I hear that a lot when someone comes in the room when I am watching a movie. That's why I try and watch movies with the door not 100% closed. But I will try that with music and see if there is a difference. In reality, it should keep the room cooler.

I've been in your room when it was warm enough to sweat, but I've usually been working. If your room is uncomfortably warm when watching a movie, or listening to music, that has to be a problem.

Oh it's been like that plenty of times. That's why I have to try and keep the lights off and at least one fan on. But sometimes, it's not as good as it should be. I always get told it's because I have too much equipment in my room. Not only do I have the equipment, but my room gets blasted by the sun for a good part of the day so that does not help. I have some vacation time coming up. So I will be able to watch more movies and listen to more music. But I have been told that my face looks red and I do sweat sometimes if I am in the room with the system on. The second fan can cool the fan pretty good though. So that's my backup plan. But yea, it does get toasty in there at times. Sometimes, you can feel a temp change when you go from my room to the hallway.

If you don't already have one, I'd suggest getting a cheap thermometer to find out just how hot it's getting. Besides being uncomfortable, running hot isn't all that good for the electronics.

I agree with that. I used to have a thermometer that you could put on a wood burning stove, but I am not sure if I still have it. I guess I could try and find a cheap in room one to use. But tonight I will break out the other floor standing fan so that should help a bit in the room over all.

Last night I did an un-scientific test. I had both amps on while I was watching TV for an hour. Then I turned it off at about the time I wrote my previous post. Then I went back in and just listened to music, which was just using the Emotiva amp. That was about 40min. Then I watched TV again for an hour. When I turned everything off at 10:00 pm Craig's amp was barely warm. I mean like nothing. My 5b-ST was noticeably warmer. My 4b-ST gets even warmer than my 5b-ST. But with both fans on, the room does become cooler.

It's amazing how much cooler Craig's amp was compared to mine. I mean I know that his is class H and mine is A/B and the power ratings might be a little different but still, it was quite the difference. I think Craig's amp runs at 60% efficiency and mine is way lower I think. Probably around 40%? Maybe? Who knows. All I know is that some one else seemed to notice the difference as well. We shall see how it is once I use the other fan as well.

Well, don't forget that a breeze makes the air feel cooler because it improves evaporation from your skin. Unfortunately, electronics doesn't sweat, so it doesn't have that advantage.

I just wish there was a way to convert either watts or heat distribution that it is putting out into actual temperature.
For instance if you look at
Max. Wattage 1562W
Max. Heat Dissipation 762W
or
Max. Wattage 1944W
What temp is a heat distribution of 762 watts. I am at the point where just
for goofs I would get a thermometer that you can put on a wood burning stove
just to see what happens.

There's not a direct conversion between Watts and Degrees. The temperature rise for a given power input depends on what and how much of it is being heated up. For example, you'll get a quicker and higher temperature rise in a small room than in a large room.

I do really hope you aren't getting hot enough to cook a meal!

I have been doing some research and it seems you're right. There is no way to easily convert watts to degrees.
There a few if's in play here. If I close my door and if I don't have both fans on, in the summer time you will be sweating in my room with my system on. I think I will try and find some thermometers that I can use to see how hot they (the amps) really get. But it does get quite toasty. With both fans on though, it does help out.

How loud do the fans get? And are you OK with them blowing on you? (That would bother me.)

The Ceiling fan is quite, but the floor standing one would drive you nuts . I am used to it. With TV you notice it more. If you are watching a movie, it's not that bad. I can keep it on the lowest speed and it's not horrible. I have it rotate so it's not on me ALL the time but it does hit you as it rotates. I am used to it. I also have to keep the lights off. That's a good thing in the long run though. You really have hardly spent any real movie time in my theater. If you want to slum it , maybe you can come down sometime in July or Aug for the day. We can watch some stuff without doing any measurements and you can tell me what you think. I won't put the floor standing one on. This week will be a good test.

My home theater is really done. I won't normally have major updates anymore because I don't see my self doing any changes. Future updates will probably just involve 4k. With a player or drive to go in my server. But I am really done. Today Craig did me a solid by coming over and replacing his amp with my "repaired" amp. Bryston said the only issue was dirty connectors. Strange, I know. But Craig replaced the amps and then did another calibration for the audio. He will tell you that my room is not easy. It's small and the dimensions make it hard to get the kind of response he really wanted. But by working with SMS-1 I think we got it as good as it could be. I seem to have a ringing at 50hz that no matter we did, we couldn't get rid of all together. That's OK. It still sounded really really good to me. In the end, I think Craig was still pleased with the results. And I am very pleased as well. We also have the SubMersive in program 2. He said that would aid bass response down low in my room, All and all I am very happy with how it sounds. I can't wait to give some movies a spin again. I know that Craig is very busy the rest of the day. Again, he did me a solid by coming over today. Craig also took some readings and graphs so maybe, when he gets time, he will drop by and post them and then explain what we did and what the issues are in my room. So know everything is the way it should be. And that's it. Nothing beyond 5.1 for me and no TV bigger than 55". So I am done. I know it's only a 5.1 system, but it's a pretty solid one. So that's it.
Thanks again Craig. I of course appreciate all of your help .
One more quick thing. I think Craig is also impressed with how good my center stage is with 2ch music. He seemed to indicate that it was right on the money. And Craig, I did find those lifters we were using so now the center is
aimed up more towards the listener.

I wish I knew where Craig was. I have watched a few movies since he came by. Looper was the latest. All I can say is Looper + my system= .
