I wish i knew than i would by them .
The krells have the biggest power supply as far as i know so they would be the choice maybe for the most difficult speaker .
I would maybe add Halcro dm 68/ 88
or the old Ml 33
I find personally the newer models not always better than some old designs, if you read what sort of technologies went into the 33 s nice , the 33 s or halcro s are also on my wish /try list
