Is Imaging Worth Chasing?


Man, am I going to be torn apart for this. But I says what I says and I mean what I says.

Here’s a long term trend I’ve noticed in the audio press. Specs that used to be front and center in equipment reviews have essentially disappeared. Total harmonic distortion, for instance. Twenty years ago, THD was the start and end of the evaluation of any amplifier. Well, maybe power, first. Then THD. Armed with those two numbers, shopping was safe and easy.

The explanation for the disappearance is not hard to figure. Designers got so good in those categories that the numbers became meaningless. Today, most every amp on the shelf has disappearingly low distortion. Comparing .00001 to .000001 is a fool’s errand and both the writers and the readers know it. Power got cheap, even before Class D came along to make it even cheaper. Anyone who tries bragging about his 100 watts will be laughed out of the audio club.

Stereophile still needed to fill it’s pages and audiophiles still needed things to argue about so, into the void, stepped imaging. Reviewers go on and on about imaging. And within the umbrella of imaging, they write separately about the images height, width, and depth. “I closed my eyes and I could see a rock solid picture of the violas behind the violins.” “The soundstage extended far beyond the width of the speakers.” And on and on.

Now, most everyone who will read this knows more about audio equipment than me. But I know music. I know how to listen. And the number of times that I’ve seen imaging, that I’ve seen an imaginary soundstage before me, can be counted on my fingers. Maybe the fingers of one hand.

My speakers are 5-6 feet apart. I don’t have a listening chair qua listening chair but I’m usually 8-9 feet back. (This configuration is driven by many variables but sound quality is probably third on the list.) Not a terrible set-up, is my guess from reading lots of speaker placement articles. And God knows that, within the limited space available to me, I have spent enough time on getting those speakers just right. Plus, my LS50s are supposed to be imaging demons.

I’ve talked to people about this, including some people who work at high-end audio stores. Most of them commiserate. It’s a problem, they said. “It usually only happens with acoustic music,” most of them said. Strike one. My diet of indie rock and contemporary jazz doesn’t have much of that. “You’ve got to have your chair set up just right. And you’ve got to hold your head in just the right place.” Strike two. Who wants to do that?

(Most of the people reading this forum, probably. But I can’t think of any time or purpose for which I’ve held my head in a vise-like grip like that.)

It happens, every now and then. For some reason, I was once right up next to my speakers. Lots of direct sound, less reflections. “The Name Of This Band Is Talking Heads” was playing. And I literally gave a start because David Byrne was standing on the coffee table. Cool.

But, generally speaking, imaging is something I only read about. And if that little bit of imaging is the dividend of dropping more money into my system, I’m not sure that I want to deposit into that account.

I think that I still have a few steps to take that will pay benefits other than imaging. But maybe the high-end is not for me.

And now shopping is not safe and easy. So things are better now?

I got this. I have a constrained space as well, 9' x 11' room with the speakers on the long wall no less. And, they are LS50's. For a long time I had my speakers 5-6' feet apart and thought they imaged pretty well. Then one day, ignoring the complications it would create, I spaced them out to 7' with about 15 degrees of toe-in. A WHOLE new world of imaging appeared. I can only get them about 10" from the back wall and I am sure the image depth would be even better if I could move them out a bit further, but not to be in this space. I highly recommend spreading them out a bit further to form an equilateral triangle and see if you can improve the image. And if you don't have a subwoofer, get one.

Your timeline is way off. The emphasis on the lowest possible THD goes back to the receiver wars. The launch of Audio Research's SP3 preamp was one of the products that revealed the flaw in that approach, and that's when high end audio was really born. The Absolute Sound was part of that movement and it goes back to the '70s - about 50 years ago.

Imaging is important and you can do it! Pulling speakers from the front wall is critical. There are many guides out there, but you might look at Paul McGowan's youtube channel or Jim Smith's Get Better Sound.

Your speakers are just fine. Good luck!
