Audio-GD NFB-12
Dec 22, 2010 at 12:06 PM Post #76 of 2,278
NFB-12 is built with dual WM8741 which supersede dual WN8740 built into DACMagic for better dynamic range. But DACMagic come with default up-sampling to 192kHz/24-bit through proprietary curve-fitting algorithm regardless of source resolution / sampling rate and also three-position digital filter. DACMagic has more input options (two sets of coaxial/optical inputs and a USB input) and output options (unbalanced RCA and balanced XLR outputs) than most DAC models in market.
 
As far as sound quality is concerned, comparison can be made when I have received NFB-12 from Audio-GD.

You've got the DACMagic too? Cool! Can't wait to hear your impressions and comparison between the two. :)

I couldn't wait anymore so I ordered up one of these.  From the stats it seems like nothing can beat the performance of this unit for the price.

The NFB-12 was never in a tweak/testing phase. It's not that different than some other designs that were already in place at Audio-GD.

Are the NFB-12 in full production and ready to sell or in pre-production and still being tweaked/tested?

I'm curious to hear a nfb-11 too but everything points to it being pretty sterile sounding.  Also if this has any performance close to the HDP (which I believe it will or maybe exceed) I'll probably sell the HDP off.

[size=medium]It should not, but you will only be able to have one of the outputs on in your Operating System.[/size]
[size=medium]But i could recommend trying the coaxial if you have no ground problem on your computer. I think it could have less jitter then the USB if am not wrong?[/size]
 
[size=medium]I will be using optical with my macbook pro for two reasons, fist the NFB-12 have a great spdif interface, and my macbook pro just has 2 USB ports… that are too close ….[/size]

Thanks, Only one or the other - not both.  The motherboard coaxial is 16bit/48kHz , I was thinking about using the USB because the DAC in the NFB12 was better? Yes?

Using coax, optical or USB, you are using the DAC in the NFB-12. If you cannot change your motherboard to output to be bitperfect or 16/44.1 (for standard media), then I would use USB to avoid the motherboard's conversion to 48kHz. It has been noted that the Wolfson chip is very picky with the USB interface, but I would let your ears decide before possibly looking at a USB/Spdif interface, like the hiface or audio-gd converter.

Not to mention the low jitter ... :)

Any updated shipping date for the NFB-12??
 
Ordered mine in late november.

I sent an email yesterday and have not recieved a response. They ship on Mondays and that was the last time the shipping page was updated on their site, so I am hoping they get them out this coming Monday.
