I almost forgot...I'm pretty sure my speakers flexed when powering up my Mc2100 before I ever lifted the sentry.
Yeah mine might have as well except now that I have lifted the sentry I pay extra attention to what I am doing! Thanks guys-

Thanks for reviving this thread. I've been so wrapped up in doing the jimmy Herring/Panic thing lately that I practically forgot my SMS/MC50/JBL rig was sitting there. I'll have to dive back into this over the weekend!

The lifting or removing of the sentry is only really needed if the output of the McIntosh is mismatched upward versus the speaker load making the amp see less of a load and pushing more current to the speaker(s). In normal operating conditions it is not usually even engaged.

i.e., two 8 ohm speakers wired parallel to be 4 ohms total impedance and then wired into the 8 ohm tap on the McIntosh.

Or 1 8ohm speaker wired to the 16ohm Tap. :-)
