HomeTheaterReview.com, February 2010 If you're an audiophile, you almost certainly know of the Parasound company, a manufacturer of high-end audio/video electronics (and other products) that are of extremely high quality, yet are not stratospherically priced. Halo is Parasound's premium line of components. (The JC 2 is not inexpensive at $4,000, but this is a high-end component we're talking about, and for what you get, that can be considered good value.) You might also know of John Curl, a veteran audio designer who is inarguably one of the true greats in the field. Curl has worked for esteemed companies like Mark Levinson, Vendetta Research, Harman Kardon Citation, Wilson Audio and others, and even worked on electronics for the Grateful Dead. Curl has been a consultant to Parasound since the late 1980s. Stereophile, March 2008 Review POSITIVE FEEDBACK ONLINE - ISSUE 34 (Max Dudious) Review         Read reviews for all of the Halo line.
