I've gone back and forth, I now use the reference curve as default but switch to flat for some movies and some music. Just depends.

 

Oh, and I have treatments behind the 3 front channels and first reflection points on side walls.

 

Do you notice much of a difference on the high end... Is it only the high end you notice as being different?

 

Are you still trying to get the "magic" back?

 

Nope, I got it back, and then I found the one part that I had thought might still be lacking... The top end is a higher now. The midrange, and upper bass have the magic in them. Now my top end is more, but I still haven't decided if I would rather have it be less like it used to be.

 

Don't notice big change in upper end in Audyssey flat. I will try it again today. My HT is heavily treated

 

Our setup had a definite increase in upper end frequency response. :T

 

My room has no treatments and I use the Audyssey setting. I've tried Audyssey Flat, but it sounds horrible. (From memory - not always a good way to proceed - I would say that the upper mids sounded bloated and the overall sound was somewhat harsher.)

 

I had a chance to listen to Audyssey flat & it does have more top end. So I agree with your finding.
Sounds great.

 

I found I preferred audyssey when setting up a car, but it seems too bright in my room. I remember reading that audyssey flat may be better when you are sitting very close to the speakers as one would be in a car.
