Best amplifier
I ordered this amplifier specifically with the Purifi Eigentakt V2 modules in mind. For those reading this review who might be a bit confused: Class D was effectively reborn through Bruno Putzeys. In the late '90s, while still at Philips, he created UcD—the first Class D module that completely changed our understanding of the technology's potential. The project was eventually bought by Hypex, and Bruno moved there along with his work. As the years passed, things evolved; nCore arrived and gave the Hi-Fi industry another wake-up call, offering high-end Class AB performance at a fraction of the price.
Bruno, alongside Peter Lyngdorf and others, eventually founded Purifi, taking Class D to another level with the Eigentakt V1 (found in amplifiers like the NAD M23 or C298). More recently, we have the Eigentakt V2, which is featured in the NAD M23 V2 and M33 V2 at astronomical prices.
Today, Class D is everywhere: Technics, Marantz (in their high-end series), McIntosh (where certain receivers use UcD technology), NAD, Primare, Mola Mola, and so on.
I have personally owned the NAD M10 V3, Musical Fidelity M6SI, and Primare i35 Prisma DM36. To tell you the truth? At 1,500 EUR, this amplifier doesn't sound like its price tag—it sounds much, much more expensive.
Paired with the Eversolo DAC Z10 using low gain settings, it sounds incredible on my KEF R3 Meta speakers. Amir’s measurements on ASR (AudioScienceReview) for these modules put them in the same league as Benchmark amplifiers, but with double the power reserves.
It has no "signature" of its own; it is perfectly neutral. The bass is extremely lively, the mids offer absolute purity, and the highs are incredibly well-represented—containing everything you should hear and nothing you shouldn't.
The OPA 1656 buffer is exceptionally well-implemented. We saw this in previous Audiophonics models tested on ASR, where they even managed to slightly edge out the reference designs. Technologically, it is a step above the Nilai 500 or NCx500.
I am also using Audiophonics XLR cables, which were delivered flawlessly. They sound impeccable, proving you don't need to drop thousands of euros on "snake oil."
In conclusion, I’ve found my go-to shop in France. Greetings to the entire Audiophonics team from Romania! Thank you for this amplifier; it is not only impeccably built, but it sounds like a dream.
