    Hypex Nilai500DIY Amplifier Review

    Hallo RQ1111 and Julf, I understand and agree with the comments of both of you. At RQ1111: Right, i also feel the Nilai is a great piece of equipment, but.. At Julf: Agree with you about the scientific approach; How about this forum, is there space in this forum for subjectiv comments? The...

    Hypex Nilai500DIY Amplifier Review

    Hallo Makis, "If the Crown had a similar effect too" (see red marked text), i guess it is useless to investigate the Nilai only, i would investigate the effect of the Fletcher Munson curve and think in that direction, since it is about relative sensitivity of the ear related to frequency and...

    Hypex Nilai500DIY Amplifier Review

    I may be missing something, but Amir explained in page 10 the cause of rising distortions at higher frequencies, the test was done with the lid open. With the lid closed it is gone. Again i might be mixing things up and be mistaken... Regards, Rob.

    Hypex NCx500 Class D Amplifier Review

    Hi Soerenssen, When reading this Forum i get the general idea; All poweramps with the same measured values, sound the "same" (not significantly worse than its competitors, which is close to what you call unlistenable). Furthermore; untill your post, every user in this thread seemed pretty...

    I use no preamp but use the Wadia Dac 121, which has internal remote controlled volume control.

    Hypex Nilai500DIY Amplifier Review

    I agree with you, although i have the stereo version i expect they have the same audio quality. I have 55 years of hifi experience and this is the first amp in my setup that i love listening to for more than 2-3 hours. Before i got tired or bored when listening to my setup with other amps, but...

    Hypex NCx500 Class D Amplifier Review

    I guess nobody disagrees about the influence of the psu, it is a fact that a smaller psu will cause the amp to deliver less power. Even laymen will understand, if somebody does not get enough food, this person will (under)perform accordingly. But i guess it is only about the word "bad". Since...

    Hypex NCx500 Class D Amplifier Review

    I don't see a problem, why should the psu completely match the capacity of the power amp board? As explained by others these are design decisions. People totally accept the possibility of choosing between engines when buying a car. As long as manufacturers are transparent about their design...

    Hypex Nilai500DIY Amplifier Review

    Since i have a complete opposite experience than you (and not with the recording you mentioned), i can only say probably the Nilai does not suit your combination. Everything shows it is a top quality product, but once and a while a component does not "fit". Like some body else tried to use a...

    Hypex Nilai500DIY Amplifier Review

    Before touching anything, besides the assembly work (because of warranty) please inform and ask your supplier first, maybe also cc to Hypex. The supplier should be able to help you out. It is also their responsibility. But trying to answer your question about the cause of the failing led...

    Hypex Nilai500DIY Amplifier Review

    So in this case, the poweramp won't overload the speakers, that's ok, but instad of the poweramp turning out too much power, the preamp can clip and that's not what you want either, because that will cause distortion and can damage the speaker also. Or is this taught a mistake? I guess here...

    Hypex Nilai500DIY Amplifier Review

    Sorry to read about your experience, Hypex is known for their good service, i am sure they will help you out, after this is over i will be very interested to read about the audio experience with the Nilai. The power socket in the rear panel has a very tight fit, i also had to push hard. If the...

    Hypex NCx500 Class D Amplifier Review

    Why a shame, it counts for every amp with high damping factor (df). Some speakers benefit from a lot of damping from the amp, others less. Some combinations do not work well. I guess in such a case there are two options, 1 a different combination, or 2 some tinkering to make the best of it. The...

    Hypex NCx500 Class D Amplifier Review

    Just a guess; Horns provide very good acoustical coupling to the air, an amp with high damping factor does do the same to the electronics. If these two interfere and disturb the feedback within the amplifier (fase shift), it might change from feedback to feedforward and turn into a mess. Maybe...

    Hypex Nilai500DIY Amplifier Review

    Hallo Andrea, I agree completely with you, my history is different, years ago i used to play with direct coupled ESL, but since using the Nilai i can listen to music for hours and hours. Last weekend i listened for 7 hours with a short break for dinner, i never experienced that before. When i...

    Hypex Nilai500DIY Amplifier Review

    Of course i respect the philosophy behind this forum, i hope the goal here is to get an understanding about matters which is based on knowledge and reason. But that is hard with such a big subjective component, where experience is the most important. Whereas in science it is not experience, but...

    It is subjective and limited, since i will write down only my conclusions so far and not mention the cd (un-compressed copies played from hs-ssd) which were being used. There is a summary of the things which were very clear at a first listen and i kept these during the listening session, if my...
