The dynamic dyno test sends very short pulse. Music is longer decay and many burst.

im going to find you some article describing amplifiers and all the measurables. they only thing that is truly continuous are static loads like motors.

I see what you're saying but without a really complex and randomized sort of warble tone that changes amplitude, that dynamic dyno test is the best reference we currently have for the performance of an amplifier on music. It really is representative of the results you would get in the real world. Especially if you're not rolling full tilt and a big dynamic swing comes through in the music. Or simply a beat driven song. That's what those reserves are for, dynamics that are well under the full potential output of the amplifier.

Yeah but can you imaging the output swings on a song. It would be all over the place.

Indeed. Dynamic, or burst power, is the figure most people should be interested in. Having a reference for continuous average power delivery potential is also something you would be interested in if you listen to strictly tones all day, but for music...

Ok money

It is, bro. That's a quality you should strongly desire in an amplifier. If your amplifier couldn't swing that, you would then need to keep the volume knob down in order to manage the dynamic swings from causing your voltage rails from hitting peak delivery. Some of the better amps turn on extra rails because the input section is monitoring the incoming signal and sees the upcoming demand.

The issue with dynamic is the distortion.

Ask yourself how any amp can gain that much power on dynamic.

The only amps you see doing that are the cheap ones. A good amp will be within 10% certified to dynamic

Slew rate.

We all deal with distortion. If you match all of your equipment up well AND use your noodle, even with distortion, you won't see failure. Lots if equipment is pretty rugged and can take it within reason. Stupidity is what gets you in trouble.

I was more referring to how long a note takes to build and end. Like a string pluck

Yep, I got you now. I was reading back on the thread and putting that together. It's a good point to make. Keeps you in the real of a music discussion, though. I suppose we could also map out the time it takes for the internal caps to charge discharge, but again, I think we really need to qualify much of what we're discussing under two umbrellas; one that describes the guy who listens to music (even really loudly) and another that describes a guy who truly does listen to tones all day erry day. The second guy is at the mercy of what it means to run full tilt and keep those caps drained, unrelenting current draw and voltage drop, and massive heat buildup/failure. The first guy is enjoying the recoup time on those caps even when he is listening loudly because the average time he spends near the rail limits is much less in comparison. Maybe he loses a little midbass attack when he listens loudly but that can be forgiven. So yeah, anyone who is in the second category needs to be much smarter about the amount and type of power they are putting on the type of drivers they are using.
It's a complex discussion , for sure. So many variables between types of drivers, amplifier capabilities, and the user's listening preferences. Really hard to make canned statements on any given day. Just that we all need to be mindful of some of these things if we plan on pushing the limits.

I'm a little saddened. I was hoping one of these dyno test would come out and I'd be blown away.

I keep putting the HCCA 4000.4 in my cart and taking it out weekly.

What it states if freaking unreal at its price point. I mean it's the largest 4 channel I've ever seen and priced less then mine.

Something has to give.

Know what I use? A 4 channel Zed with tubes in the input section. Doesn't make much power (70 "RMS" or so) but it sounds glorious. Warm, fat, sweet. Like a good woman.
Shouldn't buy for power. Should buy an amp for what it sounds like in the first few watts, like less than 10. That's where you stay most of the time, believe it or not. The rest is just used for "grip". Control over the reactive load. I know most won't latch on to that concept at first but as you go through the years and the equipment, making correlations between this type of speaker and that type of amplifier gives way to this understanding.

Listen to the character of amplifiers and speakers, then pair them up accordingly. The watts involved is such a boring discussion.

We are in a different camp on this one. I've never heard a difference in amps. Warmth in a deffinition is midbass(120-220hz area). For SQ you want as much headroom as you can get. A lot of our judging tracks have up to 30db of swing. Every component should do what it has to without any added artifacts. I can tune pretty much any speaker to sound the same as another as long as it's within its power and bandwidth limits.
