Audio-GD NFB-12
Quote: Tthis sounds a bit like you have a certain (small) AC-Voltage on the case o-) Can happen. I don't know your local power supply system. In Europe it can help to put the mains connector the other way around in the wall socket. Anyway you should check if your grounding...- Audiophil

Audio-GD NFB-12
Great, madwolf, thanks! yes, these diagrams I'm familiar with. And I agree 100% regarding the learning effect you mentioned. Personally I raised the question to kingwa to go alternativly for the NFB-11 plus the DI (in order to avoid jitter which can harm the NFB-11). We'll see...- Audiophil

Audio-GD NFB-12
checked both signals with: Dell D630 - foobar 1.1 - asio4all -usb - iBasso Viper - Beyer DT880studio Both are sounding identical, no obvious distortion. But when i had a look at foobar's spec-analyzer view I recognized in the second half of both signal a loud peak @20kHz (-20 dB). The...- Audiophil

Audio-GD NFB-12
yes, I think I understand in general. For sure some of the experts in the forum have expertise how to deal with the specific technique, me not really. But no doubt, different filters and oversampling rates have influences and I'm sure you checked carefully. I was simply surprised, when I...- Audiophil

Audio-GD NFB-12
Hi Kingwa, nice to have you in the discussion. I have been looking to > 10 devices's measurements from your link. Naturally most of them have different curves on the different sample rates. But also nearly all of them has a roll-off on 44.1 KHz of max. -1 dB @ 20kHz. This means no difference...- Audiophil

Audio-GD NFB-12
Hi Jan, I underline most of your post. Remember, I had also my reasns, when I ordered the NFB-12. But why not improve, when it is easy going? Personally I would also go for 50% more, if the result is as expected. On the other hand not everybody is able or willing to solder SMD parts...- Audiophil

Audio-GD NFB-12
Hi Killkli, perfect data indeed, I agree. This box should sound more or less neutral, not necessarily perfect, because not everything influencing the sound is easy measurable.. If you enjoy the 1543 in combination with HD600 is simple your personal taste, but means also, that you may...- Audiophil

Audio-GD NFB-12
sorry Slaughter, we are not talking regarding 'better'. This is a matter of individual taste. In case of HD650 I don't know the data, but if people report it's smoothness or softness or less agressiveness I would assume, it has a slight decrease at high frequencies. - If you wold combine it...- Audiophil

Audio-GD NFB-12
Nobody of us is able to listen locally to this instrument's 'sound' in advance. We have to trust on the information we get from audio-gd (and on this nice discussion in forum of coarse). I don't like 'sounds', because this means to distort the original signal. Several companies are offering...- Audiophil

Audio-GD NFB-12
Hi Holland, very interesting. I am not sure wether we are talking about the same filter, you mean the filter before ADC, right? If I've got Kingwa right, he was talking about the lowpass after DAC. But anyway, you are imo on the right track. As mentioned few times the filter after DAC would...- Audiophil

Audio-GD NFB-12
thanks kingwa, the link does not work for me.. For sure many devices have different f-response depending on the sample rate. But more above 20 kHz and this means not in the range people can recognize huge differences. You know, people in europe are buying a lot from the net, but...- Audiophil

Audio-GD NFB-12
Thanks madwolf, yes, the NFB-12 must sound better @192kHz, simply look at the f-response. and yes, this cannot be caused by the analog 6dB-lowpass after D/A conversion. IMO, these filters are more important for the let me say 'sound-signature' of an DAC then the Converter itself. ...- Audiophil

Hi, first of all many thanks to supecurio with his measurements! I have to say, although I'm engineer in communication electronics, I'm not familiar with the layout of hi-fi DAC design. After some resaearch I found the audio-gd solutions quite attractive in function and build quality...- Audiophil

iBasso D2-Viper (Pictures, Impressions, and Reviews): Read the Rules!
Thanks for your helpful comments, nice forum! I just ordered one D2, hoping the shipping to Germany will work ... As the website of iBasso does not provide too much information, does anybody know, if charging over USB is possible (like the Meier-Amp's can do)? BR- Audiophil
