Why don't you use an SPL (Sound Pressure Level) meter?

Also, I think most know to recalibrate their system after changing any componets.

I think this reply says it all. It's like asking "Food is important, why don't people eat it?" Answer: they do.

OK, so lots of people have SPL meters and use them. That's great.

I love hearing people describe the effect of adding or switching a component in their system. I'm a maniac about reminding everyone how critical volume level matching is because I want to be sure that I'll hear what they heard.

Analogies usually aren't appropo except on the surface but Ahbi's was funny. ;)

There is no guarantee of this as everyone hears differently. We aren't all exactly the same. The scientific endeavor gets gummed up with individuals' perceptions aren't constant. Even within an individual they aren't constant.

Good point. Perhaps we should really be seeking the opposite. If someone we trust does a careful comparison and tells us that there are NOT audible differences between X and Y, we will be able to focus our time and money on things that really will result in audible improvements.

So here's a better question: What changes have you made to your system that didn't improve the sound?

For me, I initially thought it was too techy/geeky and only for pros. Also, for some, something that you'll use so infrequently doesn't seem like a worthwhile purchase. But, since my HK has one built-in to the remote, I've come to realize the importance of it and that it's very easy to use. I'll never trust the settings on any auto-calibration feature again.

I have one and use it regularly. If for nothing else I like to see how loud the music or movie is when I am listening.

There are 3 things that are fairly inexpensive and are great investments in your A/V system:
SPL meter,
Video/Audio Calibration Disc (AVIA/DVE),
Room Treatments.

Why spend thousands of dollars on audio and video equipment and not get the most you can out of your setup?

Exactamundo.
We use the SPL meter to get the most out of the equipment we own. Pretty simple, really. It's for calibration and equalization. It's not for telling us what we like or not, or what is best, but for setting things up to an 'agreed-upon' norm and balance. After that, you're on your own to tweak and adjust as you see fit. But with the meter (used properly, and all that) you are relatively assured that you've got a good foundation to build on, or move away from. :D

cheers

Ps... oh yeah, I occaisionally check my listening levels too ;)

I agree completely. If anyone out there hasn't taken advantage of these 'big 3', you really should.

I'm in the process of building some fiberglass sound-absorbing panels for my listening room/HT. I finished the first one last night and placed at what I think is the worst reflection point between the speakers and my sofa. I wasn't expecting much of a difference because it was only one 2X4 foot panel. However, my subjective impression is that the improvement is amazing. Dialog sounds much clearer and is far easier to understand, even at low volume levels. I'll try to post some more objective data such as frequency responses -/+ the panels in the near future.
