Weseixas, Here I though The Scintilla was the only one ohm speaker. I am curious what ribbon speaker you have. I talked to Henry about this among some other things. If you want to know what a certain amp can do, call the builder.
There is a catch. The 250 watt H20, though 93% efficient, still needs the Fire preamp. It sends a boost to the H2O. With the two, I can drive my Scintillas to an in the room grand piano. As a warning, though, cables and source can react terrible with the H2O duo. With the right source and cables...... sky's the limit.
I am in N. California if anyone wants to hear what I have.
