perfect placement for your speakers

Go to one of your speakers and reverse the cables at the binding post. + to -, and - to +. See if that helps. But just make sure that you only switch the cables on one speaker only, and not both.

" The out of phase voice is thin sounding and kind of floats around your ears. You should be able to tell the difference using the method Zd542 mentioned."

On a recording that normally has a very strong, vocal center image when everything is in phase, will sound like its coming from one of the side walls. You can't miss it.

I forgot to ask if this problem only happens when you play the test CD, or does it happen on all CD's?

You need to list your system. Not just the components, but cables, tweaks and anything else that's part of it. Also, I would still try reversing the cables on 1 speaker. It will only take a minute and depending on how it sounds, you may get some useful info.

I think I see your problem. I'm not too familiar with your speakers so I did a search for them just out of curiosity. Unless I didn't look up the right speaker, it shows yours as having a single 12 inch driver per cabinet, and nothing else. On top of that, they appear to be vintage. Given the design and age of the speakers, I don't think you can expect the same type of imaging that you would get from a modern pair of speakers. Given the fact that I've never heard your speakers, I could very well be wrong, but I thought it worth mentioning. I know you tried other components with your speakers and got the same results. I think you need to try some other speakers. For testing purposes, all you would need is a cheap pair of bookshelf speakers. Maybe borrow a pair from a friend. You won't need them for more than a few minutes. If it is your speakers giving you the problem, you'll know right away.
