PA5 II has advertised power as 100 @ 4ohm, same as B100.

Like other many topping products, Amir might have one for review to be available around its release time!

You're right, but obviously B100 will measure better and cost quite a bit more.
Plus version is also stronger and all PA7 versions even more so..

Topping mx3s
Click to expand...
The MX3S is a good but low powered cheap integrated, with lesser power and connectvity than most of the competition offerings.

I also wish for a full integrated including a top dac, BT, Wifi, usb, Hdmi, a very good preamp section, enough power (double than the MX3S), very good headphone output (say the same level as the new D50/A50 III) , balanced and unbalanced inputs.

This would be a top solution and probably a great commercial success, with a quality level and VFM largely superior than the mainstream hifi proposals.

I definitely don't understand why Topping, or other good chinese brands the likes of SMSL, Matrix and so... don't offer such a device ? They have the expertise, the technology, the production force. Maybe they're afraid this will put a shadow on their too many little separate boxes ? But I don't think this will occur drastically, and on the other hand I'm convinced there is a big market for such an high range integreted offer. So, all in all, even if the little separate boxes sell less, their overall sales revenue would grow.

So are all of these amps rating power at 1khz only like cheap car audio amps of the 80's & 90's? What do they do with full bandwidth? A 1/4 of rated or less?

They do a whole lot worse with full bandwidth, full power, both channels driven. That's why they cherry pick 5W@1kHz. It's a joke.

Amir tests Power vs THD across the frequency spectrum.

Just take a look at his reviews.

What parameter are the amplifiers scored for the SINAD leaderboard based on?

Yes, with this kind of small box and small heatsink, no doubt that the output 100W or 200W can not be withstanding for 1h test. And I am even more worry about the reliability of this amplifier in the long run.

Read the reviews. The info is all there.

No. I mean a real rating from the manufacturer like most actual audio companies have been doing for the last 50 years or so. You know like....40 watts per channel from 20hz to 20khz @ .01% versus the power rating junk Pyramid car audio amps of the 90's did. Nobody listens to 1khz test tones, or pink noise for that matter, but this BS power rating is what has kept me from wanting to even try one. I don't listen to specs but would be nice to see just how low their actual power is. Maybe a real reputable audio magazine, or anyone else for that matter, will test one for real world specs.

I'm playing with you.

ASR/Amir's 1kHz@5W THD+N is an industry joke.

You can always enlighten and help the community with providing more useful measurements/parameters, will you?
Or at least suggest Amir to add a test you think is better suited for the cause!

Amir is providing whatever he can, at least helping is all in the way he can.

Dude, there is absolutely no "community". It does not exist, no matter what you might hope or imagine in your wildest, idealistic dreams.

There is no weird brotherhood of audiophiles and there certainly isn't any "cause". LOL.

Amir is merely testing a few limited parameters or audio equipment. And he's publishing his measurements. That's all, nothing more, nothing less.

By community I meant forum members and passing visitors.

Which helps, isn’t it? More or less, still something.

By the way, we also look forward to your responses and comments, those also help.

Wonder why he does it then.

1kHz is an industry standard, making Amir's results easily comparable with others.

Furthermore, with a 1kHz fundamental, harmonics fall right into the band where human hearing is most sensitive.

Low THD at, say, 100Hz, is not nearly as crucial as it is at 1kHz.

It was just a snarky remark. :)
 
5w is better than 1w, it's easier to get 1w right

I always check multitone measurements

Who has an answer-even speculative. Why did I get those 2 speakers for less than half tax in vs 1 before tax? I think I know but did you get the memo?
