This speakers where for 2,000 per pair years ago and they where well sale at the price.
If you are not convince there are many reviews out there about the RC-70.
here is the conclusion about the review.
In my introduction I asked whether the RC-70 might set a new sonic standard at their price. More specifically, I wondered if $2000 really is the point of diminishing returns for a pair of floorstanding speakers. Although the RC-70s are wonderful, I still think that this honor is reserved for speakers that cost closer to $5000, where the competition is especially fierce. Many companies offer models around this figure, and I've heard some I liked more than the RC-70s. However, that the RC-70s get very close to the quality of these considerably more expensive designs is an important point. Their sound is extremely satisfying in so many regards, and they are such highly resolving and refined transducers that I can imagine many music lovers (myself included) living happily with them for a very long time.
My advice to potential buyers of the RC-70s would be to spend money on quality electronics to extract everything they have to offer. They can sound very good with budget gear, but their performance was elevated as the quality of the upstream components improved. The RC-70s are certainly revealing. When fed a signal that is as refined as they are, the result is so impressive that one might forget all about upgrading and simply get on with just listening to music. If this isn't the point of being an audiophile, I don't know what is.
