For home use though and comparing absolute sound quality I'll defer to Mac. He knows this stuff, if he likes the sound of the heavy transformers in your quiet living room great, that's not so important at a noisy live gig.

Stop assuming things. There does not have to be a "heavy transformer" in the power supply of the amp.

The class B circuit can be powered from a modern switching power supply. In this instance, that QSC is likely indeed using that "heavy" transformer, but she is not on the road, this is for home use.
At that point, I think, from experience, that it isn't any gain to using a switching power supply compared to the durability of said supplies in the field.

There is a reason for that 6 year warranty, she should take advantage of that.


and an amp for home reproduction doesn't need all the computer controlled wow factor stuff the new crowns offer, the level of complexity there is something that Rachael certainly doesn't need to have to fool with either.
