Unlike your dealer, I am not aware that speakers have moved at all in the past decade...
I propose you go for high sensitivity speakers, more sensitive than your Zingalis. The reason your spkrs are hard at high volumes is probably because the amps run out of steam at high volumes... If so, you need spkrs that are even easier to drive.
There are many good choices and as a matter of fact there is a thread about this at the moment.
OTOH none of the companies you mention (Benesch, SFaber, etc) offer very high sensitivity speakers AFAIK.
Lovely amplifiers, btw!
