MC275 pair vs single with sensitive speakers

If volume is not an issue, is there any real significant advantage running two 275's (mark VI) with sensitive speakers like ZU Omen Defs? Just curious
That’s what I was thinking. I’m actually thinking of a 275 and a 2700 pre. I’ll still keep my FirstWatt to switch in every now and then. 
Just curious, you have 2 MC275s?  Another thing.. In stereo.. The 275 sounds better, to me.. They pass muster in mono, BUT MUCH better in stereo..

240s and 225s also... Stereo or dual amp... I like dual amp mode..Been a while. I have to look.. Some ways sound better than other ways... You can series or parallel and bridge (stack) amps to boot.. The old Macs were industrial for sure..
