It's not just about price, as there are more channels and higher power output. You can see a side by side comparison and discussion of various differences here.If possible can we get a more in depth description as to the improvements in SQ, not features, between the 8500 and the 3700.
The 3700 got a score of 88 and the 8500 got 85. Is it all about the figures, is the price increase of the 8500 worth it ?
The 8500 is getting "old" at this point. Any of the x700 series will have a better feature setup, but not as many channels (except the A1H I think). If you can get a great price on an 8500 go for it.If possible can we get a more in depth description as to the improvements in SQ, not features, between the 8500 and the 3700.

Got a score where? 88 and 85?If possible can we get a more in depth description as to the improvements in SQ, not features, between the 8500 and the 3700.

It is in my opinion that with real life usage, you cannot hear that difference.
Those are amplifier scores not AVR scores. If you are talking about AVRs it's a different story, especially if you offboard the amps. Then the DAC becomes more important.
Generally, buzz is 60 Hz and caused by a ground loop. Perhaps from a source device or your TV. If it's a hiss sound (white noise), then that is the amplifier itself and can normally be heard when the gain is turned up significantly and you have sensitive speakers.Hello, I have noticed the buzzing noise coming from all my 7 home theatre speakers when I put my ears close to the speaker tweeters.
(without any content playing)
I tried other wall socket, another power strip, disconnecting all inputs from Denon 8500HA avr etc. nothing has changed.
I asked to Denon support and their reply is as below:
"The buzz noise described is quite normal. Every amplifier has its own noise. However, this can only be heard if, as you describe, you hold your ear directly to the loudspeaker."
Does anyone have a similar buzzing noise on the speakers?
BTW, at normal listening distance, i could not hear any buzzing, only when i put my ear to close them.
If you were me, would you sell the 8500ha and buy the A1h instead just for this reason?
Thank you so much. I ll keep my 8500HAGenerally, buzz is 60 Hz and caused by a ground loop. Perhaps from a source device or your TV.

If you cannot hear it from the listening position with content playing, there is nothing to worry about.
Agreed that it's nothing to worry about, but if you wish, you could likely reduce the noise further by a) making sure your interconnects are not subject to interference by other current carrying conductors such as power supply cables, and b) replace some or all of better-quality interconnects. In case of b), it is better to try one pairs first, in case if it makes no difference then you don't end up spending too much money for nothing, c) same with speaker cables, and keep them as short as possible too.Thank you so much. I ll keep my 8500HA

I think in his case, it's just the noise floor of the X8500HA. Any time I've had a ground loop, it's been so loud that I wouldn't be comfortable putting my ear up that close to the speaker.Ground loops can even occur with XLR cables. I experienced it with my Yamaha CX-A5100 and Meyer Amie. Hiss is unavoidable unless you have high voltage preamps and low gain amplifiers. The buzz can be ameliorated by running the phone ground lug of your Denon to the ground of whatever is causing your ground loop.
I ended up using a power conditioner with a ground lug to help mitigate this.
Agreed. That said, my XLR based ground loop was audible at listening position, but not so loud that you couldn’t get close to it. The voltage potential must have been pretty small.I think in his case, it's just the noise floor of the X8500HA.

Does that mean that you will not upgrade to A1H?I learned that the buzzing sound I detected was present in all 8500s, even in the A1h.
As I said, this sound is only noticeable when I put my ear very close to the speaker (2-3cm)
Denon support confirmed this and said it was normal.
Thanks for your helps and advices.
