Topping A70 Pro HP & Preamp Review

I don't hear any distortion. Alison Balsom - Caprice. No distortion, but I will test it on wilder music and write about it. I'm falling now, she has such a beautiful voice! More low notes, punchier, faster. Requires a silver cable.
What sort of volume are you listening at?
Maybe yours is broken

Have you ruled out the headphones as being the culprit? Or the source mastering? The amp should be completely transparent.
Low gain, -28 cB. The volume also depends on the music. The volume also depends on the music. Classical music requires more volume for the same sound pressure.

You can do a simple test, try swap the headphone connector (if your headphone has dual connectors), if the left channel start distort after swap then it's on the amp, if distortion still at right channel then it's on your headphone.It’s definitely the amp as have just tried another and it’s fine
I think this amp is suit for low sensitivity planars, it can clip or destory other headphones easily.
Yes though I don't know why topping start putting orange LED in their new amps (EHA5, DX9), maybe it can make the sound warmer.Wait till DX9
I have tried that and it moves to the left. This amp has supposed to have 17w output at 16ohms, my phones only require up to 6w at 16ohms, seems like this thing is running out of steam or just cant cope at higher output.You can do a simple test, try swap the headphone connector (if your headphone has dual connectors), if the left channel start distort after swap then it's on the amp, if distortion still at right channel then it's on your headphone.

Correct me if I'm wrong...
But if I feed 5V to A70 Pro using D70 Pro, it will have peak power of 4.1875 W @ 600ohm in high gain?
Or peak power of 37.5 W @ 600ohm in high gain?

No, you’ll get the maximum rated power at a different volume put position.

Ah... okay, but is my calculation correct? Are the numbers correct?
No. The amplifier will deliver the maximum power stated by the manufacturer (1370 mW at 300 Ohms and 670 mW at 600 Ohms, balanced output, 0.1% THD+N ) at different volume knob positions. Increasing the volume If the volume is increased past this point, the output stage is saturated and only distortion is obtained.
it's in the menu's first page,very easy to find.

See page 10 in the user manual.
It was reported before, and Topping has updated a new firmware to fix it.
