I would certainly be game for spending 1/100th of the cost of a speaker to find out if it was any good. However, I would want that speaker to be one I would
actually consider owning.
If you believe what you read in those reviews, you need to start saving up, because those high dollar cables, cable risers. etc. will cost you and according to their reviews, they make a night and day difference in the sound quality.
Swerd has provided measurements and valid concerns about their $3500/pair speakers in the link below. If their design approach fares no better than this for a $3500 pair of speakers, why should we expect better for $700?
