The Model 2 has 2 gain settings and it is quite beefy as long as it doesn't have to drive through a black hole :-) The Avalons aren't so critical. The Model 2 is from sound quality definitely a class of its own.
It also has 2 different input impedances, it can be matched with a lot of preamps. Maybe there is a chance to get in touch with the Manufacturer to get a good information about speaker matching?
