Klipsch Cornwall IV

Jumper and speaker cables related.

I have Blue Jean bi-wired banana speaker wires connected between integrated tube amp to CW IV then occasionally switch out to Audio Research LS2 + Parasound A21 to CW IV with two pairs of Taralab Continuum spade speaker wires to the CW IV. 

Is it okay to leave both speakers connected to both amps but has one amp turned off while running the other? Would it cause any damage to speakers or amp? or create extra impendent and cause other side effect?  

DO NOT DO THIS!!!  The amp that is not ON will receive the power from the amp that is ON to its output terminals NOT GOOD.  You will end up letting the magic smoke out of most likely multiple components.

Agree, the proper way is with a speaker switch.  You can hook the two amps to a switch box and then have one set of leads to the speakers.  Toggle amps that way

Thank you. I will look into speaker switch. 

Just an update with probably around 250 hours. I am often times pulled out of my office chair to walk out and listen to these. They are a clear preference for me over the O/93's I owned for 8 months.
One thing I look for in a speaker is excitement without fatigue.  They have great presence but aren't hyped up in the 2-4k frequency range- that annoys me with many speakers. Strings are starting to really pop out in the room after more break in..
They play big and I can easily listen with peaks in the mid 90db range at listening position with no fatigue or ringing in my ears afterwards. 
The bass is impressive but I do notice with certain music that the low 30's and 20's are missing. The thing is the bass is really engaging so I'm fine with it. I've owned speakers that played deeper but with less engagement through the ranges, and I became bored with them. Or some speakers you crank for the bass and are screamed at with the mids and highs. These have a way of being relaxed and exciting at the same time, which is rare. Effortless might be the word.
So many unique preferences with audio, so my priorities might not be yours. They are big but any speakers take up a certain percentage floor space unless they're cramped. The front port makes them easier to position. I have them toed in so I can barely see the inside edges from the ideal seat. It's been a fun journey so far.
