Pairs of dissimilar speakers? No. Pairs of matched speakers, sure. Double Advents are well known as are double pairs of KLH-9's. Double Quads are another well regarded option. Ever consider that Acoustat 2+2 are really doubled 1+1? Nobody thought that was odd that I remember.
Personally, I run two pair of VMPS Tower II at the same time and have for years. They're side by side thank you and sound wonderful.
Anytime you see "Purist" in this hobby watch out. That's the snob side of things leaking out over the experimenter side. There's no rule that says that two pairs of speakers, similar or dissimilar will sound one way or another. If you have such and want to play about, keep in mind that you might find something you like for little or no cost.
That's how discoveries are made.
