Parasound Halo JC2

Hello Guys,

Anyone here listened the preamp. Parasound Halo JC2?
I just bought a pair monoblocks Parasound Halo JC1 , I 'll have at home within 20 days , and I'm very curious about the differences of JC2 compared to my Pass Labs X1 preamp.
Which is better .. driving two JC1s?
Unfortunately I can't listen here this JC2 and make comparisons so I'm asking tou you..

Thanks in advance for your Opinions & Suggestions
