JRDG Capri vs. Parasound JC-1

I have the Rowland Capri now and I am using it with the Rowland 102 amplifier
so I'm assuming that matchup is appropriate. As for speakers, my horns are driven by B&C DCX 50 compression drivers with 8 ohm impedance and my woofers are driven by a Perreaux PMF 1850. They are JBL Le 15B in their native JBL cabinet, again 8 ohm.
The JC-2 is on the way and I'm trying to decide whether to open the box or just sell it sealed. I'm assuming a sealed box with a full factory warranty will fetch more money than one I claim I just opened to take pictures or whatever.

So that's the real question, Do I just sell it or try it out first and cost myself hundreds of dollars for the privilege?

Thanks, Soundlock. I know the difference between the amp and preamp. That was just a faux pas.
You've convinced me to open the sucker and see what's what. Do you happen to know if the A-23 is the same as the A-21? I know it's twice the power but I'm wondering if the performance is equivalent. I also have two A-23 amps.

Rowland sold. Parasound pending. Now what?

I want solid state preamp with at least 4 inputs. Remote is necessary. On board phono would be nice but not a deal breaker. Looking for ultra quiet, hi-rez and very refined product. Not sure about budget. Will probably buy used and can handle $2K, maybe more, depending on value proposition.

Thanks, Pinkus. I sold both of them, although the JC-2 is still "sale pending".
Send me a personal email and I'll let you know how to address my $300 check.

Pinkus - Check bounced - please send a good one.
