Parasound Halo or Cambridge Audio


I'm somewhat newer into the audiophile realm and I have narrowed my starter system down to two choices: 1. The Parasound Halo A21 amp with Parasound Halo P7 preamp or 2. The Cambridge Audio 840W with Cambridge 840E Preamp. I have demoed both combos and I think I know which way I am leaning.

I would like to ask the community if they have any experience with the two as heads-up options? Pros/Cons? Thoughts /suggestions / comments....

John Curl of parasound fame as well as the big $$ Constellation
Amplifiers gives the Halo a Big edge across the board in overall
Engineering as well as in fidelity.
I think Cambridge Audio is in the same league as Adcom. The Parasound is in totally a higher league. I would go with the Parasound.
Better Late Than Never. The post is two years old.

I agree with the Parasound recommendation.
