EXCEPTIONAL PERFORMANCE
After reading ASR’s excellent review of the Apollon Hypex NCx500 stereo amp, I decided to select the Purifi 1ET400A amp because its power output (425W @ 4ohm) is a better match to my mains (4ohm > 92dB). Even though Apollon amps are made to order, mine arrived safely in the US just 3 weeks after purchase. The 400A has a simple, attractive and well crafted design. A power cord is not provided. The isolation feet could be of better quality, similar to what is found on most desktop components.
Out-of-box performance was excellent and has remained so after 2+ months of use. The 400A is silent when powered on, idling or powered off. The unit runs mildly warm to the touch. Although I have relatively high end audio components, I had always used a downstream AVR in 2-channel pure direct mode with good results. However the 400A has elevated my system’s audio response to an entirely new level. All frequencies are clean, warm and without distortion. Although my preamp’s listening volume is -30dB, when it is increased to 0dB, there is no hint of treble or mid-range ‘hiss’. Importantly, the 400A has 4 gain settings that match a preamp’s output selection (eg XLR > 20.5dB).
My system includes an 9.1 AVR setup but I highlight only the three devices from my 2.0 Hi Res music pathway: ethernet > Eversolo DMP-A6 > USB > DAC-Z8 > XLR > Apollon Purifi 1ET 400A ST >. Two North American coyotes are atop the 400A ST howling with pleasure. They are cousins of the Mexican red wolf.
The Apollon Purifi 1ET400A is an outstanding stereo power amp.

I bought three of these for an active system I’m setting up, and am going to get a fourth one in about a month. I went with Apollon for the build quality, and wasn’t disappointed. These measure well, sound great, have tons of power, and are relatively inexpensive given the level of performance you get. Can’t really think of a reason why anyone would need more than this. If I could make one wish, it would be to add an auto-sense on/off feature which would make life a little easier, but that’s really the only thing I can find to complain about.

A well built device with nice design and compact size. Yet it is obvious that this amplifier has a lot of power along with high fidelity. I like the 4 options for input gain, which gives extra flexibility when pairing the amplifier with the rest of the system. The anodized grey color I ordered looked darker on Apollon’s website, however the difference is not dramatic. The quality of connectors on the back side is especially impressive, while the power button on the front side with variable brightness is also quite nice. I listened to the tweeters from close distance and can confirm that this amplifier is silent when idling. Overall, a well-designed and well-priced product.

Hypex and Purifi have developed very high-performance and cost-effective analogue class D power modules, and I have searched for stereo amplifiers integrating these modules. I selected Apollon Audio Purifi 1ET400A ST due to compact size, elegant design, and high build quality as it seemed.
The amplifier was delivered to me just one week after order. I have now used it for three weeks with my Canton Vento 896DC speakers. My speakers now sound better than ever and excel with clarity and powerful bass.

It’s a very good amp. Too bad it is not supplied with the essential elements for its operation: a power cable.

Ich habe den Purifi mit einem Benchmark AHB2 verglichen und finde das der Purifi besser klingt…mehr Dynamik und besserer Bass…..der Nachteil im Vergleich…der On Schalter geht mir zu Tief rein und die gain Schalter sind etwas wackelig und etwas gefühllos beim Einstellen….. ansonsten ist es eine sehr gut klingende Endstufe…kein rauschen sehr klarer dynamischer Klang…zum mehr als halben Preis eines Benchmark ‘s…

If anyone is reading my review let me say your in the right place Apollon has amazing build quality the case is beautiful and your choice of colors is something nobody does. I purchased the amp in gold and the finish is beautiful. Sound quality with my Sonus Faber Lumina 11 speakers is excellent much better than my class a amp after a month i still have no need to connect my sub. For someone in their 60s the clarity at loud volumes is excellent. This was one of the best audio purchases i made. Check out my gold amp.
