Time Phase/Coherence-Vandy 5A vs. SL M-1


A couple of questions/comments:

I have had the opportunity to recently audition both the Vandersteen 5A and Soundlab M-1 speakers. I thought they were both excellent speakers.

1. I have read quite a bit about time and phase coherence in speakers. How important is this parameter in a loudspeaker?

2. Are Soundlab M-1 speakers time and phase coherent? From what I remember reading, Richard Vandersteen did not think panel speakers could be time and phase coherent.

Thanks.

So let me ask you - will your purchase decision be based on which loudspeaker sounded best to YOUR ears, or will it be based on someone else's answers to technical/philosophical questions about those speakers?
Rex,

Of course I will purchase what I perceive to be the best sounding loudspeaker. I just find it fascinating that there are so many design approaches to excellent sounding speakers. Sometimes opened ended questions/comments generate interesting and spirited discussion on the board.

Besides world class performance in many different areas, two aspects that I find particularly appealing with both the Vandersteen 5A and Sound Lab M-1 speakers is how utterly non-fatiguing these speakers are during prolonged listening.
There are some very interesting and informative threads in the archives. Type in "phase coherent" and "time coherent" in the search archive. I'm a believer in time and phase coherent speakers,assuming all other parameters are properly dealt with. Still, what ultimately matters is what speakers sound best in your system and in your particular listening room.
