Conclusion

Class D has come of age with the generation introduced by Purifi Eigentakt. The EVAL1 convinced us from day one that this technology can sound incredibly good. And now, too, it threw high praise. The Groningen-based Hypex goes over it again as far as we are concerned with Nilai. What an incredibly beautiful product it is. And for a very interesting price. For 1500 Euro you get an unprecedented high level in your home. You still have to get a screwdriver and assemble it. That makes the product, as far as we are concerned, even more personal.

    1. I loved the write up & the live stream..actually I enjoy a lot of the work you guys do. I’ve used some Class D in the past..UCD & then Ncore. Neither long term but the value for performance is quite good. I am a fan of the technology.

      Due to the Class D shout-out video I’ve ordered a Nilai. Very excited to try this new technology. I already knew the objective data was stellar but I really appreciate the subjective thoughts from 3 guys that know quality audio components & sound. Their opinions have weight in my opinion.

      I am a long time member at ASR. I love a lot of the work they do & I’ve learned a lot over the years. It’s a shame how a lot of it’s members treat others..a lot of anger at times. I just have to remind myself it’s mostly an engineering site. It’s not worth the argument or time to share any thoughts or opinions unless some data is involved. Members with more of an open mind aren’t going to share their thoughts in the forum. The hateful vultures with their $2k systems will attack. Is what it is..not worth the energy.

      Anyway, you can’t let the haters & naysayers detract you from your journey. Keep up the good work.

      • In this case is the incredible low noise floor and sheer stability of the power, which results in a very tranquil and solid soundstage. Once the noise floor drops significantly and there is nothing in the sounds that distracts, the strange effect is that it feels ‘slower’, it is as less energy is fired at your ears. That’s true for every type of amplifier or set. Once the power gets better controlled (read: less noise) it makes you feel like the whole pacing of the music slows down.

        There are a few exceptions to the rule, where the character of amplifier is still very snappy and on edge.

        • Thanks for both responses!

          To me, a very low noise floor doesn’t make an amplifier slow, but ‘have a black background’. Noise makes localization a little bit more difficult and music less detailed in case of a high noise floor.

          Distortion often detracts from tranquility and influence speed. It adds body, can seem faster but also add edginess and unrest.

          For me speed is associated with timing and bandwith and maybe measurable with slew rate.

          To me snappy seems a desirable trait while on edge is undesirable. Maybe apprehensive, although that can be both positive, want to know what comes next) and negative, afraid of what comes next?

    2. Another great listening test thanks guys. The difference between the Hypex and the others was clear enough via your youtube video and my ipad’s speakers. The Nilai’s greater naturalness, flow, harmonics and decay became even more pronounced replaying your flac files via good headphones.

      After having dipped my toes into current gen Class D with the impressive Topping PA5, I’ve been close to pulling the trigger on one of NAD’s M23, but on the back of this test I just had to order a Hypex Nilai at less than half the cost. I look forward to pairing it with my Denafrips Athena and seeing how it goes.

      As an aside, I am sorry you had to endure a couple of unkind and unwarranted comments over in a certain forum. I made the mistake of visiting it for the first time in a while to read about their Nilai measurement review, but the prevailing attitudes there are so deeply unpleasant and close-minded I would do better to avoid it entirely and suggest you might wish to do the same. The irony of banning discussion of your listening test which highlights easily audible differences between a group of very high measuring (SINAD etc) class D amps was next level, but alas terribly predictable, as it demonstrates the inadequacy of their suite of measurements to capture all an amplifier’s characteristics that produce audible differences relevant to human psycho-acoustic perception.

      Please don’t let the attitude over there discourage you from continuing your great work – there are many of us who greatly appreciate the effort you put into producing high quality comparative listening tests and measurements, letting the results lie where they fall.

      Salut!
