Sound+Image Awards 2025: the HI-FI AMPLIFIER & DAC winners
Meet our integrated, preamp and power amplifier winners and our DAC winners from the 2025 Sound+Image Awards
P801 Power Amp
- Thread starter Alan March
- Start date
@Alan March Has there been a recent change made with your enclosures that have restored the model number on the front, I see in the above Sound + Image Awards there is "P801" printed in the bottom right corner now, have all your models seen this change too like the P482 & P481 amps?
No its an old picture.

And the flip side is that if one has a reflective room, then directivity is importantly, or a narrow directivity may be helpful.
Yeah - obviously as you have a low distortion amp.
The point was that many people do like some distortion.
And usually the speaker’s distortion dominates what the amps are doing.
Usually people using Purify drivers, and Purify amps have a low distortion combination.
This combo can make the system sound quieter than an app says that SPL is at… I’ll quote myself again, at the risk of binge irksome…

Hey Alan ... I guess you going to increase the price of the P801 (and other models and products I guess) to reflect the new tariffs. If so, when will the new prices be reflected on the website?
No, this is the great misunderstanding many Americans are labouring under. We are getting a lot of questions from customers about it.
We the manufacturer / exporter do not pay the tariffs.
Tariffs are a tax levied on *you* the US consumer and is collected by the US government.
So you buy the product from us as normal. There is no increase in price. However, the courier (DHL in our case) will contact you the consumer when the product arrives in the US for payment of the tariff tax prior to final delivery. DHL are effectively the customs brokers to the US government.
This will no doubt discourage some US sales, but we are just concentrating on developing other markets. Massive increase in enquiries/sales from Canada for example. Europe has increased too.
Sadly, the only people losing out in all of this are the US consumers.
Got any links to proper research that supports this euphonic distortion theory? We will probably have to agree to disagree
.The impression of being quieter (something many comment on and which I agree) is probably more to do the slope and smoothness of the sound power and in room response. This is where many speakers fail. They sound harsher which seems louder is certainly more fatiguing.

So, for the dual P801 configuration, that is about $4K, then add the 10% Australia tariff to bring the total to about $4,400 out of pocket?

Alan, a new Purifi-specific (optimized?) universal buffer from Neurochrome has just arrived, using the LM4562 buffer. How does it compare to the Ultra Buffer?
It has specific jumper settings for the 1ET400, 7040SA, 9040BA, and other Purifi amp models. Not sure what these jumpers are supposed to do (gain settings optimized for the different Purifi models?). It also offers gains of 0 dB (1.00×), 11.6 dB (3.80×), 13.0 dB (4.47×) and 13.2 dB (4.57×).

Seems about right but just for clarity it's a 10% tariff imposed by America on Australian products but paid by Americans.
Please correct me if I'm misunderstanding Alan.
Lm4562 is not a good choice for the updated Purifi modules. It is prone to RF problems and is higher noise than alternatives.
Also, 13.2dB gain isn't high enough to get the 1ET9040 module to full power output with a 2 volt RCA source. It will get to about 575 watts instead of the rated 750 watts.
All this, plus I can see from just looking at the board, that it's implementation/topology means it will be noisier than our ultra buffer. DIP sockets for the op amp is sub optimal.
Yes you are 100% correct.
So all this extra money Trump claims he will raise from tariffs is simply a direct additional tax on US citizens.
All hifi prices are going to rise in the US because even the domestically manufactured products rely on components imported from overseas.
For example with our direct competitors:
Buckeye
- Cases from Canada
- Purifi modules from Denmark
- PCBs and other misc components from China
- Cases from China
- Purifi modules from Denmark
- PCBs and other misc components from China
So for a company like Buckeye who were already selling close to cost, this is very serious.
Also, as I mentioned previously, due to tariff retaliation from other countries and the anti US sentiment that Trump has created in the rest of the world, their export markets have also just tanked.

We pray and hope this tariff war will be over and done with by the end of summer. I believe many are delaying their purchasing until all this is over.

Probably was optimized for 4V XLR sources?
Then why gave a 27dB gain setting? 23dB is correct.
@Alan March I just noticed that Purifi have released a new "Deluxe" edition of their input module (FE05) the EVAL5 board, https://purifi-audio.com/shop/eval5...,8692,8693,8694,8695,8700,8696,8697,8698,8699
Perhaps Neurochrome has based their new Purifi board design off of that, the Purifi EVAL5 board offers "Total system gain options of: 13.5dB, 20dB, 23dB, 26dB & 27dB" but doesn't offer 29dB Gain so isn't quite suitable for 2V RCA sources like the P801 provides, is the reason that Purifi left out that gain option because they utilise the Hypex SMPS1200A180 PSU which will not yield full power output anyway?
I dont think its due to the Hypex psu as its capable of driving to module to full power at 8 and 4 ohms. Its the
2 ohm rating it will fail at.
27.7dB will raise 2 volts to 48.5 volts which equates to 588 watts with a 4 ohm load.
27.7dB is far too much to be optimal for 4 volts input. So really not sure what these choices are all about.

Alan... have you thought of prioritizing your business for the US market? I'm talking about advertising in well-established, wide-circulation magazines such as Audioholics and Secrets, as well as attending consumer audio shows like CES, CEDIA, and AXPONA, which is currently ongoing (or may have already concluded). It will be in Chicago, IL, from April 10 to 12 next year, so there's plenty of time to prepare. The travel cost from Australia might be a bit of a pinch, but the exposure will be worth it. These shows attract many European and Asian audio manufacturers, even though some focus more on video and technology gadgets than audio.

The business already does well in the US. We also have lots of plans for growth that include the US, but right at the moment, until the unpredictable situation with Trump is resolved we won't be investing money in the US. Too much risk.
Plenty of other markets to concentrate on in the meantime. Markets that are growing because of Trumps actions.
