pre-amp processor

If you decide on the ACT4 ,  be sure you have a good dealer who knows the

products he sell.  Some dealers carry 20 brands . They do not know everything.
A home theater processor is a complex gear .  No dealer is able to solve the 

kind of programing issue with my firmware . Only one person at IAL has that knowledge . It makes , owning IAL processors  , quite risky.

Sounds like the Lyngdorf might be my best choice 

I’m still torn between the two 

McIntosh MX 170 uses the Room Perfect room calibration  too

And you have a very solid brand that still , should be in business 10 years from now …….
