Advice Please On Possible Vandersteen Purchase

Vandersteen's work best for a seated listener at least 8' away. You might still prefer them to others at different listening positions, but that where they really come together. IMHO, though not terribly picky about ancillaries, the lower models can be a bit room fussy.

Unsound, thanks for responding. I do sit at a table facing the Cambridge/Wharfedale set up. The vintage gear is behind me on the opposite wall. I'm around 7-8 fret away from the former and maybe 12 feet from the vintage set up. I may also add that stands are not available in the deal, he doesn't have them.  Wondering if 1500 for new Wharfedales or much less for these Vandy's.  
  

The new Wharfedale evo 3’s for $1k are awesome!  Might be something to consider :)

There are a lot of options between <$200 - $1500.

$200 for the pair is certainly a good deal!

I would grab them if in good working condition ........
if they are original Vandersteen 1 series they could be 30 years plus old that being said they are still a unique Boxless Phase and time-aligned design that may bring some joy into your music world.
Placing them a foot out from the wall with just a very small bit of toe-in.
Place speakers so that your listening area is in a triangle or 20 percent out of it. Put a deck of cards under the front of each speaker for a bit of tilt back and find some used Audioquest speaker wire type 4 or CV 4 and AQ cheap source interconnect Red River Put on your favorite music after 4 days of run-in, you will know what’s up enough if its time to source a pair of Bases that will step up the clarity to another level. As an experiment, you may want to remove the other pairs of speakers way out of that area as they will sponge off the clarity of the particular speakers you are trying to evaluate.

Thanks all. I'm setting up a date to go look at them and hopefully hear them too. Will report back.
