CAT MAN.... let me help a brother out...! Thanks for trying to educate these people.
AP amps are not reliable, inefficient, and customer service......what customer service?
An amp that is upwards of 85-90% efficient will use less power, put out less heat and will be less likely to fail when pushed to the limits.
You also can't beat the sound quality of even the "budget" MB Quarts, Cadence, and several other "budget" amps. Don't forget, Good amps used to start around $250 and go up from there. Now you can get a "good" quality MB Quart, Cadence, etc for $150 on up. SPEND THE EXTRA $40 YOU CHEAP BASTARDS!
