Denon AVR-X3300W 7.2 Atmos/DTS:X A/V Receiver Review

Glad you feel that way!



Yes, it's the (a little over) 100db peaks that I was after, 100db average would be too loud even for me

Did Denon ever release the promised firmware update to Dolby Vision?

Great review. Does anyone know if turning ECO mode on affects sound with external amplification? I’d like to have my Denon X4400H run cooler. It gets very hot.

Whether you are using your AVR's internal amps or not, setting it on ECO mode won't affect any external amplifiiers connected to it. The pre-out signal level will not be modified.

For the heat problem, you can get AC Infinity fans from Amazon at very affordable cost. AC Infinity have several fan systems available to cool electronic equipment. I use the Airplate Series 5 system on top of my AVR using three 100mm fans with excellent results.

Thanks! I have ordered a pair of AC Infinity fans to help with cooling as well.

I find ECO mode reduces the temp by around 10 degrees F!
As Verdinut implied, it only effects the amplification section, downstream of the pre-outs, so if you run all external amps, it is a no-brainer. Personally, I would not hesitate to use ECO mode with the internal amps (aside from the front three channel).
I did not notice an audible difference between with and without ECO, but figure I won't take the chance on the front 3 since I have external amps available.

I have also started using Eco mode and the Xfinity Fans. Heat is no longer an issue and the sound does not seem affected to my ears! Thanks!
