Yes. However, I unplugged everything but the speaker cables and still saw the issue.Same HDMI cable as with the new Denon?

All amplifiers have some amount of noise. Your speakers are very high sensitivity, which is going to mean you'll hear some hiss, especially when close to the tweeter. Best option would be to replace your speakers with something a bit less sensitive. You could shell out for a very clean amplifier like the Benchmark AHB2 (https://www.audiosciencereview.com/...-and-measurements-of-benchmark-ahb2-amp.7628/), but all this will do is reduce the amount of hiss slightly.I guess this is a possibility. But is this expected? That the brand new, flagship receiver would have a hiss.
Plug the headphones and without any input connected, turn the volume up.That’s what I expected. Which is why I found that peculiar and out it in my comment.
It does get louder once I pass volume 85 or so. At which point I can hear it from my listening position.
But pretty much constant before then. At least to my ears.
Headphones ? I’ll give it a go.Plug the headphones and without any input connected, turn the volume up.
How bad is this hiss/noise?
After that, do the same test with the older AVR and compare.
I will make an assumption, that there is no dedicated headphone amp in these AVRs.Headphones ? I’ll give it a go.
Just curious what would this tell me. Say I do or don’t get a noise through the headphones ?
Volume 85 is volume above 0 on the relative scale, so if you have very sensitive speakers, and ears, then I can understand why you can hear hiss from your seats.That’s what I expected. Which is why I found that peculiar and out it in my comment.

Which Klipsh speakers do you have, what's the sensitivity?

I am planning to upgrade these sooner than later. But, for now, I have these to contend with.If this hiss phenomenon should be a Klipsch specific issue, then it should be a well discussed »feature« within the Klipsch owners’ community.

If I raise the volume past 85 or so the hiss increases and becomes audible in the room.
when it is on, I can hear the 2 front speakers + center hissing if I put my ear within 12 inches from the tweeter.
Thanks.Wow, so the specifications show 96 dB/2.83V/m sensitivity. The A1H preamp/dac section is likely very quiet, comparable to the AV10, AVM90 etc., but the same cannot be said about the power amp section.
That, combined with the 96 dB sensitivity of your speakers, compared to those with sensitivity 86 dB/2.83V/m, the hiss will sound like 10 times louder. Based on all the information shared so far, the hiss you are getting may actually be normal. Is it possible for you to do what Ban25 suggested in post#224? Not suggesting you buy another pair of speakers but do you have (or borrow) something less sensitive that you can try, something that has sensitivity around 87 to 90 dB/2.83V/m?

I don't know about that, let's read again what he said:
How often would people with 96 dB/2.83V/m 8 ohm nominal Klipsch speakers set their AVR's volume anywhere near 85? I guess likely never. Most people probably won't go pass 65.
He also reported that:
Again, how often do people listen to music or movie tracks that close to the tweeter, especially tweeters for 96 dB/2.83V/m sensitivity speakers?
I expect the preamp/dac section would be near silent, so if you connect to pre out to power amps such as those based on Purify modules, or the Benchmark AHB2 it would be near silent too. That's based on speakers with sensitivity no higher than 90 dB, for 96 dB such as yours, if you are very sensitive to the hiss frequencies, I think hearing it from 12 inches in a deal silent room is probably expected.Yeah. That scenario will never happen. I agree 100%. But again, is this what’s expected? From my end, I thought that the top of the line Denon receiver would be dead silent. As in no music playing = speaker is off completely.
Hope that makes sense. Also, I can adjust expectations if my expectations were off.
my point exactly.If I’d purchased a 6 or 7k Euros AVR, I may not only be over-sensitive towards hisses from that device but of those from my wife, too.
OK – quite honest: In this case, I can understand any bat ear sensibility completely
my point exactly.
Yeah the other thing is they are combo speakers with built-in Atmos speakers on top -- so if you are standing close listening for hiss, you're actually going to hear it from both tweeters at once!I am planning to upgrade these sooner than later. But, for now, I have these to contend with.
I am sure some will say yes, but others may say no if they think the price is too high.Isn’t it OK to demand of an up-to-date audio amplifier to put out nothing when it receives nothing to amplify? All the most if that up-to-date audio amplifier costs about a sum equal to the average yearly income of people in South Africa, for instance?
I guess it’d be ok if this were my previous $500 receiver. But Is this expected at this price range?
I don’t have the top atmos speaker plugged in. Only the main speaker is wired to the receiver.Yeah the other thing is they are combo speakers with built-in Atmos speakers on top -- so if you are standing close listening for hiss, you're actually going to hear it from both tweeters at once!
Sound quality is a drastic step up from the old cheap Denon receiver. I will probably end up getting a 2ch amp. However, my next step is upgrading the speakers.Did the $500 receive do better, worse, or much worse? And aside from the hiss, do you like the overall sound quality, or you have plan to use external amps eventually?
