Impact of phase inversion by preamp

This will be my first post on this forum so I thought I’d pose a question I’ve always wondered about.  I have a Conrad Johnson Premier 18LS preamp that I’ve been extremely happy with since first acquiring it some years ago.  This is a solid state single ended, single stage design that inverts the phase of the input signal at the output.  The manual states that you should reverse the connections to the speakers to account for this.  Obviously this is easily done but I really can’t see how it would really matter as long as things are connected consistently between the left and right channels.  I’d be interested to hear what others have to say on this subject.

I get similar results when I switch as merosen gets. I find the sound stage seems to be most effected when switching also as Merosen noted too its a little hollow-dead sounding in the sweet spot when switched. 
I switch it when I'm listening and doing other things in my place (cooking for example) and when I'm sitting. The larger sound scape is useful if your not sitting as I find in my place it opens up the sound and disperses it better but the sweet spot suffers dramatically. so uses for both for me.
