Parasound Halo JC-1 and JC-2 How good are they?

I had JC-1's. I thought they were great and better than the Nuforce 9SE's that they replaced. Then I went back to the Rotel RB-1090 that I had before the Nuforce and Parasounds and I'm happier. Go figure. You have to try them, everything I read about the other amps was true but I still find the Rotel more satisfying. Synergy and all that stuff.

Hi Rossman and others,
I do have the Parasound equipment in my system. I'm reasonably impressed. The equipment is very dynamic and open. Vocals seem float from the system. However I'm not detecting that last bit of harmonic bloom and richness that my current system has. The amps and pre have been on and "breaking in" with a break in CD for the last two weeks.
I'd think the units have settled, but maybe there is more to come?
Right now I have mixed feelings.

You will need at least 350-500 hours or more of playtime to hear their true potential... so be patient.

So any comments about the JC-2 preamp.

Quote from Stereophile's review of the Magico V3:

...The Parasound Halo JC 2 preamp and Halo JC 1 monoblocks, which had worked so well with the KEF 207/2s, were just too lean with the Magicos...
