I bought a D90SE to replace the digital inputs and preamp part of my failed NAD M10. Since the Topping Pre90 has all these remote control problems I'm going to skip the preamp and try and use the 2nd balanced input of my PA5 with RCA adapters for my phono preamp. When the Wiim Pro comes out I'll use that to feed streaming sources to the D90SE via coaxial.

Topping PA5 Review (Amplifier)
- Thread starter amirm
- Start date
Hi...I am considering buying it now, if the early failures cause has been found and fixed. Too many pages (252!) to browse through, the last post of Mr. John Yang was about power at 1% distortion. Shall I consider buying or should I wait a bit longer?

Bought it month ago. Still working. Sounds excellent for this money. Warm, detailed with excellent transients

There's been no announcement from Topping that the issue is resolved.
Personally, I'd still consider this as a risk - one for you to weight up. If you buy then have a strategy in case it fails (e.g. local seller with good service and returns policy) or be ready to be without an amp for several weeks if you don't have a backup.
It's a great amp when it's working

Yeah, has to be aimed with Webb Telescope precision. My Pre90 is working extremely well with my PA5 but I have my components next to my seat so no remote needed.

I also bought from the same seller i think yesterday, same price, like new. Unfortunately even though it sounds incredible it has the static issue in the right cahnnel reported by others in this thread so is going back

When nothing is playing. Its exactly like a video another user posted in here before
Right, mine’s going back tomorrow. I had delayed a return after noticing the static sound for months but not minding it. It kinda went away if you put the amp volume to max. Well this evening I came back to it and the left channel has completely failed. So off it goes.
Last time I make the mistake of buying expensive stuff from China. I don’t have a spare balanced amp so I guess I’m using headphones for a while.
I’m tempted to just pick up something like an Audiophonics MPA-S250NC and call it a day. Sell the replacement PA5 when it’s eventually shipped back in a few months.

good call
Can anyone confirm if this audiophonics power supply will work with the topping? It’s 48 volt and I haven’t found out yet if the topping can handle higher voltage.
Could this 32V 10A version have any benefits over the stock PSU? I don’t know how many amps the topping can draw but with the other TPA chip amps more current lead to more 4 Ohm power
I recommend using the attached power adapter.
The voltage of the power adapter attached to PA5 is 38V.
This is the highest voltage of the TPA3251 chip used in PA5.
If a 32V power supply is used, the maximum output power will be greatly reduced.
In addition, a special power connector is used for PA5.
To use other power adapters, you need to create a new DC power cable.
However, using a 32V power supply will reduce the output, but there is also the merit that heat generation will be reduced.

No-one can answer that without the /missing info. Id suggest contacting susvara to ask them.
Why would you want to use a PA5 speaker amp for 60Ω/84dB headphones?
The PA5 only provides ASR measurement results when connected to speakers.
In order to use PA5 with a headphone load, it is necessary to lower the volume greatly, and it will be used in the area where THD+N has deteriorated, so there is no advantage to using PA5. It is also unknown whether PA5 operates stably with a load impedance of 60Ω.
For headphones, I suggest using a dedicated headphone amplifier.
