Topping A70 Pro HP & Preamp Review

[DrCWO]

Got my second unit a couple days ago. I'm starting to hear crackling in the right ear now, even without a record on the table. Anyone know why?

I guess your phono preamp outputs a small DC voltage. Attach a voltmeter at its outputs and check.

Does anyone know if I were to send my broken amp back to Topping in China, would it get tariffed on the way back into the US?

I just got one of these largely based on this review as well as others.
What an excellent amp, hooked up to my OPPO Sonica I can't imagine anything sounding any better.

Hi Folks!
I have a class d amplifier for my living room, feeding my passive speakers, I was thinking of using the Pre90 as a preamp, but I've seen the A70 pro which also has a headphone amp, I use headphones at night so I need a headphone amp, is it crazy to use the a70 as a preamp for the main amp in the living room? Will it perform just as well as the pre 90?

Ive used A70pro as a preamp in my no. 1 set for about half a year now and been very pleased with the performance. Xlr cables to hypex main amp and rca's to sub - works like a charm, looks good and is compact and one gets a state-of-the-art hp amp aswell.

Not at all


Yes.

What other hp amp/pre would you propose as a safer choice but with same features and specs?

 

[Tovarich007]

Why "safer" ? Is there anything unsafe in the A70 pro ?

Reliability wise hp amps do not have the best record.

I learned (the hard way) that the warranty for Topping amps is 2 years but headphone amps is 1 year. Plus you have to ship back to China for service and pay tariffs to reimport.

If you are in the EU and buy inside the EU everything has 2 years guarantee. But for 500+ plus euro hp amp i would like something worry free

That is a comfort, but if it fails you will still have to ship it to China. :/

Not quite true. It’s on the dealer.

That decides it, I’m moving to Europe!

No i send it to the shop in the EU. It is his obligation to send a new one.

If you want a truly worry-free HPA, then buy a Violectric or Lake People.
I know of enough units that have been working flawlessly for at least 20-30 years (in daily studio use). Failures are virtually unheard of, and even if there is a problem, the manufacturer or a technician can repair the unit easily and inexpensively.
A used HPA V200 costs €400-500 and is on average 10 years old and should last at least another 20 years.

Good to know thanks!

Trigger question

I’m currently using the A70 Pro as HPA and Preamp. Is there a way to switch off downstream devices (power amps, subwoofer) by 12V trigger when I put it in HPA mode?
If not possible yet this would be a great option for Topping to include in an upcoming firmware version.
