What are the advantages to a Class A amp & what are the trade offs?

I can beat that! My wife glances at the electricity bill once a month:)

Ignorance is bliss.

Class-A has yet to be equaled in my experience.

Correct, if done right.

Why do many of us spend $$$K's on our equipment especially BS cables, for only 10% "if any" in sound quality increase over something that cost a 10th or 100th of the price.
Yet we cry murder for nowhere near the extra cost of using Class-A amps and the power they consume, (Class-D users are especially known for this)

It’s true, George. I think the extra electricity may come to $50 a month, maybe $70, if I listen a lot. It does annoy my wife sometimes but I try to calm her down by pointing out that we don’t own a car, lol, and save a lot of money that way.

People in New York burn $50 at Starbucks in a couple of weeks. I make my own coffee for fifty five cents a cup, I calculated the figure. So, skip Starbucks and listen to a Class A amp. 

Larrykell, you have to try San Fransisco Bay coffee. French Roast. Great stuff!.

Hi George, I have to agree even if you like funny looking class A amps.
but I do make my own cables:)
