Classe CA-100 stereo vs bridged


I currently own (1) CA-100 in stereo mode. Was thinking of getting a second one and bridging it.

My questions are:

1) Will there be any sonic degradation?
2) Will the input sensitivity change?
3) Will driing a 8 ohm speaker that has a 6 ohm minimum be a problem?
4)

I'm thinking the answer to questions 1, 2, and 3 would be "no", however, I have no idea for question 4.

What speakers are you using? Do they need the extra power?
edit: 3) Will driving a 8 ohm speaker that has a 6 ohm minimum impedance be a problem?

Speaker = http://www.troelsgravesen.dk/Jenzen-NEXT.htm with woofer http://www.troelsgravesen.dk/Jenzen-CA_files/CA26RFX.pdf which is a option for the design.

Lets save question 4 for later :)

During my loudest listening sessions, I am measuring 95-97db with 106-109db peaks. Its taking about all of the 100 watts I have to get to this level. Its doesnt sound clipped at this level, but there is a hint of strain.

I dont want the xtra power to go louder than this, rather be able to accommodate this level with more headroom and ease for the amp.
