Parasound JC-1 still one of the leaders?

What's the forum's opinion on the JC-1 relative to some of the newer challengers such as the Ayons, Pass '.5', Modwright, etc. Not to mention the increasing acceptance of Class-D amps such as Spectron and Bel Canto?

As the JC-1 was released circa 2003, do you think that it is starting to age a little?
