RE: Big Small Amp

The point is the level of output at class A - since class A delivers current to the load more quickly, you have faster transient response. Also better dynamics so long as you are within the Class A envelope.

It is like 20-25 watts on the 150, which is like the XA 30 all class A (they also weigh about the same and cost is very close, and they have about the same number of output devices. You are very likely playing outside your class A envelope on most of the loud passages and on all substantive transients.

It is 50-60 watts in the 350 - like in the XA 60 - here you are probably not running out of class A power till very loud passages and most transients are mostly if not fully developed before their power gets delayed - as we wait patiently for the power supply caps to (please) discharge already so that we have the current on hand.
