ZERO Feedback talk. Monarchy amps.

I know that the average SS amp design have a neg. feedback upto 50dB which lowers an input impedance significantly.
I know that we need to apply neg. feedback due to the non-linear output characteristics of transistors or even tubes.
There are the cases when I can see either low or no feedback on tube amps and I understand that very often you need no feedback on tube amps.
The Monarchy audio came up with SS amps that have zero feedback. Did anyone listened to them? The thing is that I do not personally believe that it's possible to implement SS amp with no neg. feedback.

I feel that Bear is getting to the right point. Far not every brand giving out circuitries but yet I'll get in touch with the manufacturer as suggested to educate myself.
I remember a long time ago reading a Bryston 3B-ST ciruitry that is using an active neg. feedback stages that do not reduce the input impedance(more sophisticated than gain stages)!
In SS case most of the powerfull amps are multistaged especially class A designs since they tend to keep all amplification elements in the small signal operation(prepare to manufacture some power plant for such amps!)
