Topping A70 Pro HP & Preamp Review
- Thread starter amirm
- Start date
No. Square waves / impulses don't make sense for sound. If THD/IMD is ok I don't know why you'd take a look at squares. Is there an explanation for this test? And for Topping's advertising?

Anyone have a video or link to a video that shows the screen in action? You'd think a product with a screen with digital meters would be easy to find examples of it in motion.

There are no reviews out of the product, other than this one*. Which is sad. It's a promising product for sure.

I'm using Topping DX7 Pro+ currenctly and consider to upgrade, this looks attractive so I'm checking reviews about it.
About the real load test, I checked Hypex DIYpreamplifier's measurement, it has state of art performance too, I guess it just a hair better than A70 Pro for the high frequency IMD.
What's the difference if an AMP does not have overshoot issue? Can we see the difference from regular measurements?

I know real world does not have square waves, but topping's material is a bit confusing me.

I found no videos too, only pictures.

Upload it to YouTube, set the video to unlisted so that only those with the link can find it, then post the link here.
- I've never uploaded to YouTube, but I'll try!

Exactly what I wanted to see. Thanks!
Wait till DX9
The drive is Ifi Neo Stream, 24 bit/xxx file.
Surprisingly fine sound, no sharp highlights. Perhaps due to the drive (iFi), a warmer tone, which is very good for many headphones.
Dynamics, stage, balanced sound. I love it! Sadly I sold my Hifiman HE1000SE headphones, and they would have winged it!

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
.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
