Do YOU have a flat frequency response in your room?

I may have a very simplistic view on this topic, however getting your listening-space "right" to get the best representation of what you're listening to is more important than chasing component upgrades without it.  A great book in my opinion is "Get Better Sound" by Jim Smith.  I have used it to set-up my large listening-room 14 years ago and recently in my new smaller space in retirement.  Up until I really considered the room being the issue, I swapped-out a number of different components including speakers, preamps and amps chasing improved sound.  I found that while the sound did change some for the better, I never really enjoyed it as much until I worked on the room.  Once I got the room "right", when I changed components and speakers, I felt that I could really flesh-out the differences/improvements much better than prior to that.  I bought my audiophile friend a copy of that book and it too changed his whole perspective on how the room affects the sound.  Most of us mere mortals have to live with the physical dimensions of our listening-spaces.  It's what you can do within those confines to minimize the effects of the room on the music that makes a great difference in anything you do component wise in the future.  This has been my experience.  

@liquidsound +10, you articulated the entire point of why I started this thread in your post, thank-you. I will order that book too, first I heard of it, thanks!

@kota1   You're quite welcome...  I believe you'll enjoy the book.  It goes about the basics and is easy to understand.  It's been a huge help to me.  

Happy Listening !
