Magnepans: single or bi-wire?

I have a pair of 3.6 maggies that I've used with great enjoyment over the last year. I've run class D amplification (Spectron Musician MKII) with Speltz bi-wire...no complaints.
I am reconfiguring my system and would appreciate hearing from others who have experience using single rather than bi-wire speaker cable runs. I most likely will be using Clear Day speaker cables going forward. I appreciate your thoughts!
