It looks like the room correction on the Lyngdorf works the best also 8k.
The Acurus warranty is far superior than any other brand and USA made.
maxwave you have the act 4 how simple was it to calibrate and set it up?
the Lyngdorf has 5 2.1 hdmi in and 2 out
the Acurus has 8 21. ready in and one out
I'm still torn between the 2 units with Anthem AVM 90 close behind
What do you think?
