1000 watts in Class D and Class AB

What it comes down to is attention to detail. Those that listen and those that hear.

What type of class D are you taking about ? analog or digital ?

WTF?

Class D's have switching outputs, that does not make them digital amps.

As squeak has made abundantly clear...those types of statements are purely opinion.

It's great you dig a/b's. I dig my D, but I'm not going to tell you you're full of it just because you hear a difference and I don't.

I WILL tell you - all the authentic abx unbiased listening tests that have been done have arrived at the same conclusion. There's not a difference.

Funny, I just read an article the other day saying the exact opposite of what you just said.

Any links to said article.
There is unfortunately a lot of hogwash published by magazines/etc about this topic as well, which helps to delude people and perpetuate the myth.

I'll go out on a limb and guess this publication sells a lot of ad space to companies explaining why it would be a good investment to spend hundreds of dollars on their signal and speaker cables.

After running my RF T1000-1BD at 4 ohms, I don't think there is a difference in sound. Now if I were running my amp @ 1 ohm I might not feel the same way.

topology can dictate sound..only thing is we are not dealing with .1% distortion vs 10% LOL. You also have to account for how the amp will be used. Are you using the amplifiers xovers? Are you going to use the amplifiers eq? If you have a good external processor things level out pretty quikly between amplifiers. Sure you might have to fine tune between different amps but that is part of the set up
You also have the prestige effect that super expensive equipment has. What I base as good vs bad is how well does a product sound without having to do any special tuning/ or super install..rarely does an amp fall into the catagory of impossible to make sound good. Next thing you know people will be saying they can tell the brand/type of speakers a car has by listening to it.//content.invisioncic.com/y282845/emoticons/wow.gif.23d729408e9177caa2a0ed6a2ba6588e.gif

My audiocontrol 3.1 also makes a huge difference in the performance of my amplifiers.

No.

Exactly.

This isn't a debate, so stop bumping it. What squeak and n2 are saying isn't opinion, its the truth.

Honestly, I can say that this thread has defo gone wrong.

I back a/b amps simple due the the higher damping factors and the better control it has over the cones movements. But then again I only use pure class A amps for my mids and highs. and A/B for my woofers. SPL,SQL and SQ are all about just one thing how well the amp stays true to the source and controls the cone of what ever speaker it is driving.

Class D amps do have there place but they were developed as a more eff. way to produce power in cars that were not able to support the draw of an a/b amp.

Another fact into a soft clip a class D amp will draw MORE power than a class A/B of the same ratings. And the last time I checked your average installer/ consumer does not have a scope meter sitting around to check gains and clipping levels with. Even if they do there is no industry standard for recording levels on MP3's or CD's so unless you educate the consumer they are still going to overdrive amps to clipping and burn coils.

Alright enough of my rant. Enjoy and see who has the bigger E-parts.........

What about Class D VI limiting at low impedance loads????

OK, I will run from the hornet's nest now:laugh:

oh no.

What's their idle current draw?

The difference that some hear between AB and class D isn't the distortion level but the dampening factor. This is why some class D's sound better than others. Higher the dampening factor, better the control thus having a better sound. Class D amps were never designed for anything over 300hz matter of fact I wouldn't use them over 100 hz but that is just me.... If it wasn't for class D amps we wouldn't be running all that power we like so much //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Polo.

I'll break down the differences in plain and simple terms:

Class D = cheap power for high school heroes and wannabees who fail at life and therefore must exert their bad poetry to a beat on those around them. It is as if they are saying "Hey, look at me, I am somebody because I run 3,000 watts RMS to my subs but power my factory speakers off the head unit!" Don't get me wrong, they also make great power for burps in competitions, so they do have their place.

Only the real men run Class AB! Why? Because we don't care about DB numbers, we like how our music sounds. We also don't care about the lengths of e-penises by riding the current boner product of the month because our amps have lasted years, and in some cases decades!
