I see you have Maggies. An easy load for any amp capable of suppling the current. What did you do for the external crossover? New inductors and caps? I'm leaving my stock crossovers alone and working toward a Passive line level crossover between pre and main amps. Schematics exist to pretty much duplicate the stock crossovers transfer function. However I don't understand what drag racing has to do with amps. In the 'real world', the amp which best drives normal speakers will sound the best. And by normal speaker, I mean speakers that look like either a capacitor or inductor (at various frequencies) TO the driving amp. Maggies are exceptional in that they are a very benign load only moderately deviating from resistive. Since I have MG1.6s, I'll use that as an example. Data exists for the 3.6, as well. I havent' seen measured data for other models, even my original MG-1, which I owned for 20+ years. www.stereophile.com/content/magnepan-magneplanar-mg16qr-loudspeaker-measurementsThe first graph shows impedance and reactance data against frequency. You'll be hard pressed to find a more benign speaker load.

So basically what this shows is that if you drive a Lamborghini and a Kia @ 10 mph in a control driving environment, the Lamborghini won't be any faster. That is a good way to waste anybody's time. Take the Lamborghini and the Kia to the drag strip for a quarter mile race to see what happens. And that my friend is the real world. The real world involves driving on a highway at 65MPH. The analogy is flawed anyways. What people are talking about here is if you need X power per channel that anything that provides X power will do the job and sound the same.

Maybe that is your "real world" but not mine. Moreover, I bet you that most people, maybe certainly not you, will rather drive the Lamborghini regardless of speed. I see that you are still contributing to your agenda.

memotiva, I responded to your post with some of my reasons against DBT.

No, no, you were talking about the "real world" in a general sense. Don't change your topic now that you can't defend your position. Again, your entire analogy is flawed regardless.

In General, it is MORE FUN to drive a slow car…..fast, Than a fast car……..slowly. My Miata was not fast. But it sure did great in the hills and mountains while keeping up with nearly anything. Straight line? Not so fast. It might have actually been more fun than my S-2000, especially in wet conditions or when I wasn't driving 110%
Also, power is NOT the measure I'd worry about. Rather, the ability of an amplifier to drive REACTIVE loads is king.
Some speakers have very high phase angles which chews up lesser amps and spits 'em out.
IF Emotiva were to publish Power Cube data, I'd be convinced. However, NOBODY publishes such data. Most people don't know what to make of it and some amps which are highly regarded would crap-out so bad, they'd never sell again.

Again, your entire analogy is flawed regardless. I presented the analogy for review and feedback not for negative criticism or approval or state it as a fact, but you already know that. You are the one who is wrong because I am far from trying to defend myself. I am just here trying to learn and so far you haven't teach me or mentioned anything that I don't already know. You need to try harder if you are trying to insult anybody's intelligence....

Just trying to gauge how much you DO know. Please tell me how much you know about Power Factor. And how this applies to either 1. Amp into the wall plug OR 2. Speaker being driven by an amp. Simple is good, so I know what you DO know and what may be useful.
