I don’t fear modern technology, even though I’m convinced that Skynet will soon deploy Terminators to destroy the human race. I do however, fear modern manufacturer's marketing specifications.Bill Fitzmaurice wrote:I recall much the same said 40 years ago, when transistors began to replace tubes.

Boy did I laugh.:New class D amplifiers without heat-sinks are the most evolved (and evil) form of programmed obsolescence that I know. They are designed to fail after a few years (just out of warranty) due to thermal cycling, dust build up and corrosion. A fair engineer would never throw air directly at a PCB. This is easy money for a few ones today and lots of garbage and ruin for the planet and us tomorrow.
Why won’t my XTI1000 drive a 250w driver at 8 ohms full range with the input signal correct and the attenuator open without clipping? My Com-techs and CTSs will.
Why does the Drive rack tell me to set attenuators at 55 percent when the XTI is selected without knowing my gain structure?
Why are there no engineering specs for any of the class D amps?
Why do amps with engineering specs cost 4 times as much?
Why did speaker manufactures invent a program power spec which is conveniently twice continuous and recommend an amp that matched program? (Please don’t quote manufacturers, I’ve read that)
I AM NOT bashing class D technology, I would just like to know what to expect when I buy one. If I can achieve a limiter voltage, I would like to be able to achieve it under load. I’m not too likely to leave my input signal at 1khz and say “sounds good doesn’t it?”
