No comparison - the W-10 all the way, and the more affordable W-6's smoke the JC1s. Remember, the Parasounds are built in Taiwan, are not balanced (huge error on Parasound's part) and have a pretty face. They charge $6k because the contractor who built them (Parasound isn't a "real" company - they don't build anything) has to do a large quantity, so for them to recoup their investement quickly, they have to charge a higher price. The Sims are hand built, using really good parts and an excellent design. Plus they have a 10 year warranty and if you need parts the 15th year they have them. Parasound, you're SOL after 7 years.
