Thank you all for the inputs.
I had to put this issue on standby for a while and when I got back to it, I followed a different path.
Bought a pair of monoblocks from Temple Audio and I'm very happy with the result. Everything I was looking for, I found it in these little boxes. They output 100W in class D and the sound - signal coming from the McIntosh C712 preamp and going to the Zu Omen Def - is fantastic! Clear, powerful, amazing soundstage at a very affordable price.
