1) Best of show sound when I heave heard them and that includes soundstage and imagingyou can say that about every speaker.
2) Unique crossover design that provides an easy load to drive.....even a few watts of tube power can do very well with excellent bass extension for the size and few if any other high quality speakers this size can do this particular trick
3) Only high quality third party parts used and yes also high quality cabinet.
4) These can deliver a lot of top notch sound especially for smaller monitor speakers off most any amp.
5) Top notch sound + top notch quality + relatively small package for all that = top notch value.
