I thought that you were using AudioGraph' s "Active Load box"Switching to my PowerCube Loadbox, we can simulate more complex loads:
This factory provided chart is an illusion and simple theory. I have made dozens of tests of A07 with 48V/10A power supply and the best it gets is about 150W/4ohm before clipping, or 180W/4 ohm if you allow for 1% distortion.As usual, they list different power levels, depending on the selected Power Supply.
Would be wasting time, it will be the same because of the TPA used. TPA based toys are all similar.Can this test?
it would be interesting comparision if price is the criteria to have measurements of moderately well made chinese class AB amplifier modules* around same price point.This factory provided chart is an illusion and simple theory.

Could you publish the measurements for different PS values, if you have them ?This factory provided chart is an illusion and simple theory.

I don't eitheri dont doubt his figures really
Like this Reactive Load Test presentation better.An ideal amplifier would follow the red line. We are essentially there for both 8 and 4 ohm. Surprisingly this little amp managed to also keep running at 2 ohm, albeit without capacitive component and some power drop. Many amps simply shut down and won't even work into 2 ohm.
Interesting that tech/subjective reviewers-cum-gurus like Martin Colloms back then, always highly rated most of the worst measuring amps in his reviews, yet at the time, the better measuring (for IMD not just harmonic distortion) amps all sounded lean toned, 'thin' and with odd bass. The only 1980's exceptions being UK-Audiolab and a couple of high output current HK amps of the times, which to me all sounded very similar. It's reviews like these which robbed the UK market of so many otherwise nice amps I feel and mostly because of the religion surrounding two UK makes in particular which I was part of I admit at the time.Seems so much better than much of the 70s/80s stuff of similar power for the price.
In your dreams!You can still upgrade all 5 op amps to get better sound. Thanks for the great review.

Not laughing those 5 op amps not genuine.Thanks for the laughs!
How can that even happen?My Aiyima A07 Pro Always ON
Sorry about that. I had tested it but forgot to put in the review. It is there now:Can this test?
