Concerning phasey, I've never tried mixing sereo down to mono - seems like sacrilege to me -lol!
But phasey could make sense:
The Ty2 Live Grand is made up of 2 voice elements - very similar/seemingly identical to my ears when sounded separately- except one is panned hard left, the other hard right in normal use.

To my simple mind if you coalesce these elements into 1 mono channel you have 2 "identical" waveforms superimposed - hence an opportunity for phasing - noticed by some, hence the phasey comments??.
