New Topping PA3s offering on the corner?

[Drengur]

Looking forward to tests. I messaged Shenzen moments ago, I will probably not be able to wait until the testing is done. The only problem is I have too many Topping products.

Typical THD+N will be in the 0.002x% region, SINAD 92dB or so under Amir's test condition.

That is very impressive, especially for the price.

 

[Drengur]

I'm sold on it.

 

[V.b.]

Now we need a 130$ dual Merus power amplifier, no volume control.

 

[Vladetz]

Going almost to 97 db sinad, very impressive

Are these the correct cables for connection an XLR balanced pre-out to the PA3s and similar amps with TRS balanced input? Or is there a different wiring scheme for TRS balanced vs TRS stereo connections/cables?

This looks correct to me.

If the performance is on par--and I expect it will be--this blows away the $220 Sabaj A20a for value, and the combo with the D10S Balanced will cost roughly the same as the SMSL AO200 while probably providing better measured, though maybe not audible, performance. However, it does have an external power supply, while I believe the other two have internal.

PA3s also does not appear to have a remote. I am very desktop focused these days so had not even noticed.

Interesting. The Sabaj A20a is not a power brick amp... It has an internal Morsun 350W PFC PSU.
It would have been cool to have the same concept here arf....

A20a, you mean? Just guessing, but it was probably much less expensive to repurpose the existing tooling for the old PA3. And also faster to market and a smaller case. One of the tradeoffs for the $70 cost savings.

New topping PA3, PA3s

According to audiophonic in france theres a new Topping PA3 called PA3s So a picture of the amp on facebook (audiophonics) where they say just under € 170 incl tax

No more power then the original PA3

The Sabaj A20A (my bad) is about $230
The Topping PA3S is about $175

The Sabaj A20A has good Internal PFC PSU @ 350W (LOF350-20B24 ) and XLR inputs and Sub out + remote control
The Topping is a power brick amp (26VDC probably 6A or 7A about 180W ) with less common TRS balanced inputs

Most balanced dacs are equipped with XLR, so you will need a good TRS > XLR cables.

I imagine there is something for every taste and every wallet.
As for the measurements, we will know more soon I hope)

@JohnYang1997

What is the DC input voltage range you can use with the amp?

 

[gasolin75]

$218 https://hifi-express.com/products/sabaj-a20a-balanced-stereo-power-amplifier-nw1194-class-d-amp

Theres clearly a difference in power

4-26V supply voltage range for the MA12070 chip

How the hell is 200W+ is possible then?

Edit: I misunderstood, Sorry.

If you want to know more about the SABAJ A20A, I dismantled it entirely here :

Dual Merus MA12070 Amplifier Sabaj A20 fully balanced : pictures inside )

Even if it is, you would also double the amount of EMI those two produce. Oh yeah just jokes. There's no need in my use case. I did think about how if I did ever decide to adjust up the volt pot on the Mornsun I'd get some EMI shielding tape to split the PSU and amp board while I was at it. And...

I guess he's talking about another incoming amplifier.

 

[gasolin75]

cutting it pretty close, the pa3s is nowhere near 200 watt
