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)

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.
Yes, the 600w 4 ohm mono rating is a bit suspect, but irrelevant in my case since my impedance low is about 6 ohms.

Thanks for the replies.

Id still like to hear from others as well if anyone has some input.
I suppose a little more info would be helpful here. I am running a Rega Apollo into a passive pre amp (goldpoint 25k stepped attenuator). So my pre amp has no gain capability. The Rega drives my CA-100 to near its rated output on most material. So, therefore, I cant afford for bridged mode to yield less wattage per the input signal.

Al is right in that a CA-100 in bridged mode isnt something I need to drive to its 350 watt maximum. Rather, whats most important in my situation is that the Rega can drive the bridged amp at least to the same wattage levels as before.

It sounds like, which ever way one chooses to look at it, that given the same input, I will have more output in bridged mode in terms of watts yielded.
