Is soundstage just a distortion?

Years back when I bought a Shure V15 Type 3 and then later when I bought a V15 Type 5 Shure would send you their test records (still have mine). I also found the easiest test to be the channel phasing test. In phase yielded a solid center image but one channel out of phase yielded a mess, but usually decidedly way off center image.

This got me thinking of the difference between analog and digital. At its best (in my home) I am able to get a wider soundstage out of analog as compared to digital. Which got me thinking- is a wide soundstage, one that extends beyond speakers, just an artifact of phase distortion (and phase distortion is something that phono cartridges can be prone to)? If this is the case, well, it can be a pleasing distortion.

It's a little ironic that there are such things as records and CDs that test for soundstage since the soundstage you get is going to be limited by the, uh, limitations of the system you play them on. Kinda like seeing an ad for HDTV on your old fashioned 90s Panasonic. The HDTV picture quality in the ad is going to be limited by the constraints of the Panasonic. Wasn't Opus 3 another record label that "tested" for soundstage?

I don't see any irony there, Geoff.

The basic purpose of a test record or CD is to facilitate assessment and identification of the "limitations of the system you play them on."

It seems fundamental that when you want to test something, the performance of the test equipment (in this case the record or CD), in terms of accuracy, quality, etc., should be much better than the corresponding characteristics of what you are trying to test.

Looking forward to receiving mine:) And the others too!

Thanks, Rodman.

BTW, I was going to word it a little differently, Al;) You certainly didn't take the words out of my mouth.

Al's comments are on point. Goeff's reference to the Opus 3 recordings, especially 'Depth of Image' makes me wonder though what would have happened if I had never heard that record over a system which had its soundstage capabilities optimized. I used this disc for years as a goal/reference when trying to establish my own system. But, if you had never heard its capabilities in the first place it wouldn't mean so much - it still sounds great and you might not know what opportunities for improvement exist.

Hi all.

Just read this entire thread. I have to say that Mezmo's post had many good points and was well articulated - very good post Mezmo! Actually, I found many good posts in this thread. It's been a good read and very interesting.

However, when Mezmo stated: "They bounce off of stuff, stuff can get in the way, the room can resonate at weird frequencies, they can bounce into each other and either cancel each other out or get excited in strange and inappropriate ways, in short, they can get into all manner of trouble." I know he was referring to sound waves, but it sure did remind me of my buddies and I attending our first junior high school mixer.

Sorry to interrupt. Intermission is now over.

Please carry on,

Tim
