I did say it would probably sound good, but it won’t get the best from these speakers.
Look what happens to the power transfer of the Prima Luna (black trace) into the "mild load" of "Kantor" speaker load, and the Sonus Faber’s are much more severe than this.
There will be a big power drain around 100hz -200hz region because of the SF’s 2.1ohm load at 135hz
