Hello, my Crack kit is in shipping, but before it comes I thought I'd ask about using a RCA Y-splitter to the Crack. I have the JDS Atom as my other amp, and it has two inputs. I was wondering if it would be ok to send my DAC's signal (100 Ohm output impedance) to the Crack and Atom's RCA inputs at the same time, even if they have very different input impedances (100K vs. 10K Ohms, which combined in a parallel circuit makes 9.09K Ohms), and then connect the Crack's output to the Atom's other 3.5mm input? I ask because I want to send the Atom's RCA out to an estat energizer and switch between tube and solid state easier. Thanks.
