I have had my 861 upgraded tuesday evening. Did some listening tests, and find it to improve the sound a little.
As i had not much time yet, and the install was only done late in the evening i got only yesterday to listen.

The total sound image improved, also without RC like written above.

I have however 54 filters when i do the automatic procedure. Seems all but a perfect room [Linked Image from softronix.com]
