Comparing One System to Another - A + B

The TL;DR version: Positioning the speakers and listener is critical to getting good sound. And perhaps you need to work on that in your LR system.

You can get help from Jim Smith's book and video, Get Better Sound.

Do you mean up towards the ceiling? Mounting speakers on the wall is not recommended for good sound, but putting them above ear level is really not going to sound good. You will not hear any direct treble. Just as bad, Dirac may try to correct that by boosting the treble.

And sound from 20 ft away will inevitably be more blended and less "crisp" (as you put it) than sound in the near field.

Though you may need larger speakers for that room, I think the NAD should do well. It has Hypex amp modules, which can sound great. And 180 wpc should be OK for moderate volume listening.

The dealer may have run Dirac, but it will pay you dividends to learn how to operate it yourself and make changes as needed. If you haven’t already, pay the $99 for the full-range version.

And do get the speakers off the wall, onto stands, and look on the Web or in Jim Smith’s book for advice on positioning them and the listeners.

The speakers are mounted on the upper corners of a wall in our living room 22' x 16' as a compromise with my wife.  However, they are directed slightly downward pointing toward the seating area.  So, they are pointed toward listening as much as possible.  I realize it would be better to have them floor mounted and larger, but this is the compromise I have to live with. 

What is interesting to me is how much the tonal quality of the sound of the B&W speakers in the living room is similar to the tonal quality of the B&W speakers in our Volvo.

You recommend paying the $99 for the full range version of Dirac Live.  I've checked on their site and the full suite version is listed as $349.  Do you have any recommendations where the full version can be purchased for $99?

Please let me know.  I feel that I need to learn to use it.  Thanks!

Right after I wrote this last note I also wrote Dirac regarding the $99 full version of Dirac Live.  They just sent me the link to it.  So, now I have the link and just purchased the full version.  I find their site rather confusing.  It would be helpful if they had a simple page showing different versions, benefits, prices and download links for easy consumer comparison.

I think you're right.  I just need to bite the Dirac bullet, learn the full version and play with it to get the best sound available under the circumstances.  In the meantime I'm also enjoying listening to the playlists on the Tannoys and the Volvo.  It provides an interesting basis of comparison.

Thanks for all the help!!
