Vandersteen Speakers.. Are All Other Speaker Makers Doing It Wrong ?

Nope. My speakers are the bestest. 
 

Seriously though. I had a pair of Tekton DIs and a Lyngdorf 2170 with room correction. One thing it does it correct timing in the DSP. The DIs sounded downright messy with the DSP off comparatively. Never heard Vandys but would like to. They do however need to be convincing with rock music or your out!

They have been around for ~45 years, so I suspect you could find a place to have a listen.

I would suggest bringing an LP or CD of what you like and are familiar with, and then you can compare them with the Textons.

The room will be different, but at least you will know. Plus I don’t believe that I have a Texton dealer near by… so it would be good to see.

We don't need no stinking dealers, so says Eric Alexander.

My JBLs have slam and definition, =realism. My $.02. And at any volume level.
