"Does anyone have any first hand experience with the Parasound Halo JC 1 ?"
Sure, I have owned a pair for 2 years. Initially they were my reference until I modded some older Adcom GFA-585's. They gathered dust for about a year until I finally modded them. Now they are my reference again. In stock form, the JC-1's are a bit hazy and undynamic in the upper frequencies. A bit of HF sibilance, but this can be fixed. The only amps that will have better bass control than the JC-1's on your Dali's is a Carver Pro ZR1600, but one you have to get modded to be decent.
