Audio Physic Virgo I (or Virgo II): still considered a very good or great speaker?

 Audiogon offers a large variety of USED speaker of varying ages and design. I am curious if speakers like the above are still considered viable in terms of audiophile sound quality. I ask because any purchase of so-called "vintage" speakers  pose a risk in terms of performance and sound quality, especially against newer technology speakers

I have heard the Virgo I about 15 years ago and liked it very much, and every time a pair come up on AG or e-bay,  I am tempted to buy them, even a  VG pair especially considering the large body of positive reviews and testimonials.  However,  I always nixed the urge to buy them new because I thought the original  retail price was overinflated which subsequently pushed the RESALE price up.  I have seen decent pairs for pairs for sale for $1500-1800; however, my intuition tells me that they are worth no more than $1100 even in near mint condition. 

I guess I am basically asking....is it really worth it to buy used speakers approx.15 years old, no matter how much they have been praised .,or pursue newer speakers and speaker technology  

Thanks, S.J
