Does the Vandersteen 1C Hold Up to Modern Standards?

There are a pair of Model 1C speakers in my area on the used market. We don't get many of them up here in New England. I am considering going to listen to them and possibly buying them. I'm in a small room (14'x9'x7'). They look to be in excellent condition and they are inexpensive enough that shipping the woofers (if needed) back to Vandersteen for re-foaming is still a good deal. I have a good subwoofer I can use if needed. Since I'll be listening in an unknown room with gear I don't know, I just want to put it out to see if anyone has experience with these. 

I currently have Wharfedale Evo 4.2 speakers and find that they sound a little tubby in my space and I just wish the imaging was a little more open. The vertical dispersion of the AMT tweeter is pretty bad, so I have to be sitting for the tonal balance to be correct. I've moved them around quite a bit within the available space. They are on the factory stands and are located 3' from the wall which has a built-in bookcase. 

I listen to large ensemble jazz, orchestral music, pop from the '70s/'80s, and a variety of other music. I enjoy scale and dynamics of the large ensemble music I listen to, but I'm not a headbanger by any means. 85 dB peaks do me just fine. Not a fan of speakers that are too forward (B&W/Focal, etc.) 

The rest of my system is a MacBook Air, Bluesound Node, Schiit Freya+ Tube Preamp, and a PS Audio Stellar S300 power amp. 

Any thoughts before I go over there are appreciated!
