Looks like Parasound has been busy. On top of the JC5, they've updated/improved the heart of their line up. The P5 gets a better dac, volume system among several other items, and gets renamed to the P6. The A21, A23 and Hint all get upgrades with more power and become the A21+, A23+ and Hint 6. Looking good, I want the A23+ for sure.
Edit: All of the updated models are on their website, and internet dealers have the new models' descriptions and specs.
