Wobbly XLR Connectors on Pass X250.8. What to do?
If they are Nuetrik connectors there is a hole in the center used for locking the connector to the shell.  Take a small flat blade screwdriver and turn it to the right about 90 degrees to lock. 
Mcintosh, Krell or Mark Lenvison Power amps
Another Krell vote from me.  I have a pair of KSA 250s powering my Divas.  Been happy with them for about 25 years now. 
Krell KBX crossover.
If your using an active crossover I assume you would just bypass the passive. 
Amp repair cost — is this right?
I recapped my 380S a couple of years ago.  Not too difficult a job.  It is a wonderful classic piece. 
Mark Levinson preamp no. 38 vs 38s vs 380 vs 380s
I love my 380S.  Since these units are getting old and the case has no ventilation, you may want to consider a recap. 
Recapping Krell FPB-Monoblocks - Need Advice
If all you need is a recap any good technician should be able to do it.  No need to send your equipment across the country.  I would not operate the amps if they easily overheat to avoid additional damage.

Krell KBX crossover.
The KBX is a superb crossover.  I am using one with my biamped Divas.  Unfortunately, modifying the crossover frequency and slope is difficult since Krell has no documentation.  I have information for the B&W 801 speaker so if you are able to ... 
Magnepan LRS compared to the .7 or the 1.7i ?
Don't bother with the fuse and jumper.  Just do a simple rewiring to bypass them both (no soldering required and easily reversible).  I did this to my MMGs and it was worthwhile. 
Using Mark Levinson No. 380 preamp output simultaneously
It's not a good idea because it unbalances the balanced signal.  The single ended output is taken from the non-inverting balanced output.  If the two phases of the balanced output see different loads they are no longer balanced. 
Using Mark Levinson No. 380 preamp output simultaneously
You can use it but it is not ideal.  The manual urges against it.  A better solution is to use a splitter off the balanced output and an active balanced to single ended converter.

What problem are you having with it? 
Levinson 380S with sub
The record outs are only single ended.  Levinson does not recommend using the preamp balanced and single ended outputs at the same time (you would un-balance the signal by applying a different load to each phase). 
Levinson 380S with sub
You could use the record out but it would be a little cumbersome when changing inputs.

I would hope the unit was recapped.  Check the power resistors.
