Burmester 909's (MKiii or 5) vs Soulution 700's

Anybody have opinions on which one of these amps is better, generally?  Fully aware it depends on speakers, but I'm looking for general opinions.  (My speakers are Krell LAT-1000's if you'd like to comment with more specificity.)  Also would like to know more about the difference between Burmester's 909 MKiii and MK5, if anyone on this side of the pond knows, lol.  Limited info and experience with Burmester in the States it seems.

Really appreciate any opinions and info!
