Topping A70 Pro HP & Preamp Review

[Pell22]

A fault is suspected in the low-impedance high-power section. (4.4mm balanced out)

A70PRO is dying in low impedance headphones like he6se, susvara.

What the hell is going on?

OK I think I'll hold the horses until this is sorted out.
According to the manual (troubleshooting section), a restart should solve this. I guess you tried it already, but just in case.

I've tried it. except for the input and output devices, I cooled the heat and turned it on again, but it's still the same.

SMSL should take this situation seriously and release a safer and more reliable amplifier by fully replicating and improving the topping's amplifier circuitry.

Well believe it or not, I've seen dozens of a70pro dead in S.Korea and it is no joke. One even died at the start of a DAC blind test. Which messed things up, like a lot.

Tanchjim and Topping, bruh

 

[fatfat]

I am an a70pro owner.
Due to the death of the amplifier, it is being used only with low gain until there is an official mention of topping.

I've been using A70 pro with stealth and expanse for some time and didn't have any problems so far, but last news are not very optimistic.

Don't worry.
I'm using a 'Stealth' and an 'a70pro' and haven't had any issues so far.
However, the 'a70pro' did go down once when I connected someone else's 'Susvara'.

You mean Topping, right?

nah I don't think so

nah I don't think so

aahh now I understand after reading you post again. I was almost ready to purchase the a70pro but now waiting again. It happened with the a90 discrete which I decided not to buy.

Why did you decide not to buy the A90D? because it's the old-fashioned?

First of all I found out that it has low input impedance which is not good if paired with some DACs. Secondly A70 pro came out

 

[Tony Roma]

Well it seems that Shenzhen audio are in denial, saying theres no fault with the amp i returned, just more reason to avoid them, finally got a refund but i had to pay return shipping which cost me £40, you live and learn, never again.

 

[oozy]

just got A70 PRO today after 1 hour of usage i have error HP DC abnormal and it wont go away after powering it up and down again stay away from topping A70 PRO i bet it will happen to you as well in few days or hours seem like really faulty design by topping part really unprofessional work..

Topping needs to solve this problem quickly. -_-

I love Asano Tanch

Ok, so just before the D70 pro/A70 pro came out I'd bought the D70/E70 stack. Aside from the cool display, what am I missing out on?

Another A70PRO death has been uploaded to the Korea community.

Topping hopes to provide a solution as soon as possible.
