I found a few new ATMOS titles crackle when I send the audio via hdmi bitstream to my AVR. When LPCM is sent the crackle is gone. This means the AVR is not able to properly downmix or unpack some new ATMOS titles.

It sucks ATMOS is not fully backward compatable as promised, but time marches on. A new AVR is on the horizon I guess.

I have been doing some testing with a denon 3300 I recently installed in a setup. I might go back to mainstream AVRs, maybe a 6300/7400. Not sure I like the idea after having an Arcam. The new Arcam AVR supporting immersive audio is ridiculously overpriced.

In other news the completed towers are doing great. A wide dispersion setup like these are making me rethink my setup. Changes on the horizon.
