FYI - Parasound begins shipping the new JC5 stereo amp based on the JC1s in June. Review samples have already been sent out to press. My local dealer is the first in the US to get one (arrived Tuesday) and I should have a chance to give it a listen this weekend.
The Parasound Halo JC 5 Stereo Amplifier will be available from Parasound US dealers and international distributors in June 2018 with a suggested retail price of $5,995.
