^ draw your conclusions from real life not from others writings... RC has changed his mind more than once in print... nice to see someone found the carver challenge I have been harping about though

Do you think there is a difference between "real life" and an isolated test procedure?

Because there isn't, both are "real life".

The only difference is one is based on subjective opinions on what caused the change while the other isolates and explains precisely what the change was caused by and -should- leave no doubt.

I love amp threads

Incidentally, you can't get power from nothing. If you have a 25amp fuse, stress it 50% so it rides the edge but just never blows, and run an average of 13volts, you are topped out at 488watts available, multiplied by the efficiency of the amp for theoretical max output of maybe somewhere in the 400watt range... Shows how much of that 900watt amp you actually listen to

I think they're just good reads and help noobs in particular weed through a lot of bs when shopping for electronics in general. I think the biggest point made by those challenges is that the differences are so small that it's really not a big factor when choosing amps and maybe more effort should be placed on other factors...price, reputation, application etc...especially for those with "normal" systems that are not at the limit of install and tuning where perhaps a certain amp may add a certain je ne sais quoi.

you are reading a bit much into my comment, I could have said "read then listen for yourself and make up your own mind"... it is not like this is scripture. And I have no idea what isolated procedure and opinions your talking about.
I am not saying anything provacative

From what I think I've learned so far, if I go with the audison set-up or any a/b class amps, I would have good sound obviously but I'd be maxed out on less power and pay a premium in value. If I go with any D class, they makes gobs of power ,cheap too price wise, a little less sq and the system would have a broader range of tunability or I go with something in between those two classes ...more food for thought.

Go argue that one with Steven Mantz. There's a lot about car audio and "audio" in general that is b.s. Have a read at the zedaudiocorp.com website, lots of interesting reading material. The Leviathan will do rated power @ 4ohm load with a 30A fuse, @2ohms it doubles to a 60A. If you would like to listen to a sine wave all day long you will require a 105A fuse. Music is transient, this is where efficiency really plays a key role and this is the part that is not mentioned enough imho. I'm not saying all Class "D" amps are created equal, but I can say that the Zed Audio equipment made by Steven Mantz is quality stuff, and maybe power wise, sq sound, form factor, and flexibility make it the best amp on the market. So in short, right now at least, or until everyone starts copying his design, his amps are without equal imo.

I will go threw the entire tech talk on the zed website tomorow. This week, I'm buying an amp. My personal deadline is September 30th.
