Let me run another scenario by ... Say I wanted to run both pairs of speakers simultaneously with two stereo amplifiers. That would simply require Y adapters off of the single set of krell KRC preamp outs????

At 1.7 ohms unbalanced output impedance the Krell KRC HR will have no trouble driving two stereo poweramps using a pair of these.
I agree with George's response, of course.
Also, if you want to be able to listen to a single pair of speakers while having both amplifiers powered up, you could put a line-level switchbox between the preamp and the amps. A good choice would be the DBP-2JAU/5 ($110) made by DB Systems, as listed on this page. (See the "photo" and "review" links just above the listing of that model number). At a higher price point ($349), you could also consider the Decware ZSB.
Finally, in addition to the y-adapter George cited you may want to consider this one, which costs a bit more but comes from an "audiophile approved" manufacturer :-)
