Dave, no I would not call the JC1 nor any $4000 amp mass market or even close to "semi-mass market." To do so would be to not understand the big picture of the market. Personally, I would call Sony mass market. And Marantz, Yamaha, Peachtree as semi-mass market (they try to cater to the masses who want something better than average, but yet they still distribute their products via mass market big-box retail channels). In the big picture Parasound (and especially their Halo line) are 'high end' or boutique or whatever you wanna call it.
