Biamping with very different amps

Thanks Al, I value your opinion.  The current drive train for the 107/2s is Parasound (JC 3), JC 2 BP, 107/2 KUBE, and JC 1.  When I replace the Esoteric SA-60 with an Ayre DX-5 DSD, a Bryston SP3 may replace the JC 2 BP so HDMI can be used for SACD and BD surround.

I've used a CAD 572 SE to drive LS50s with surprisingly good results, so that stirred my imagination without thinking it through.  The sensitivity of the LS50s is 5 dB less than that of the 107/2s, so I may try setting up a switch between the amps, but the 107/2s do sound magnificent driven by the JC 1s -- a JC 1 also drives the Reference 204/2C center.

The 107/2 KUBE has both HF and LF level controls.  I've tried the 107/2s with and without the KUBE, and prefer their sound with the KUBE.  As I understand it, the 107 and 107/2 KUBEs differ substantially.  The 107/2s remain among the best sounding speakers I've heard, and driven by the JC 1s do a credible simulation of the sound I hear at pipe organ recitals and jazz clubs.  I've abandoned the crazy idea.
