well, I found the text ...

it was a comment on six Moon, Nicholas Bedworth ...

and +, just below ...

here is the chapter that interests me!!!!
""""" The number of options combined with Klaus’ personal involvement in the sales process means that he’s essentially running a bespoke operation including biasing the output stages to match a customer’s speakers and listening preferences. One consequence of these methods compared to the never-ending stream of boxes coming out of Shenzen is that delivery of your new Odyssey amp might take a while.
Specifications: Klaus is not all that keen on pushing power output as a key specification (sort of like Rolls Royce stating that the motor of your Phantom V had adequate horsepower). He believes instead that goose bumps are a more useful criterion for evaluating product performance. However, for those who must know he points out that the nominal power output is 175 watts RMS into 8 ohms, 320 watts into 4 ohms and roughly 600 watts into 2 ohms. Hobbyists report that the Odyssey amps are not only stable into 1 ohm but also that the power output easily reaches 1KW into that impedance. The DIY crowd also prefers these specific Sanken transistors as they can deliver in home-built designs a staggering 1000 watts into 8 ohms or 2000 watts into 4. """"""""
if Nicholas, or Klaus could give more details ...

power for extreme stratos mono 8 4 2 1 ohm ...

and another question ...

what are the amps are adapting to the impedance of the speakers automatically???
or they are set to depart for low impedances???
thank you for your answers ...

Ducky.
