I have a marshall 1960a, I'm getting a dsl50 soon, it can be set to 4 Ohms, and so can the cab.
Will 4 Ohm's be better than 16??

What will the different be?
yes, so if i run my amp and head at 4 ohm's rather than 16, it will let more current run through, therefor being louder?

thank-you for that.
no, the DSL is a full tube amp, so it uses a matching output transformer. It will put out the same power if you are using 4ohm head to 4ohm cab, or 16ohm head to 16ohm cab. The transformer is matching the very high impedance of the amp circuit to the much lower impedance of the cab. Mismatching in either direction will result in less power.
