Couple weeks have passed, no more reviews -- nobody else purchased the NFB-7? ccschua, is your unit burned in enough to post some impressions? thanks in advance!
Really looking forward to your impressions I´m looking into ordering an NFB-7 or 8 in the near future...
Pacific Walve is a Audio-Gd's retailer - so, his pronouncement is not credible. In the other words is a load of bull****. Marketing's gobbledegook.
Me too, exactly the same choice: NFB-7 or 8.
So far my choice is rather the 7 with upgraded clock and this is because I like Sabre as much as I can tell from the NFB-10ES.
But I never heard the Wolfsons. Kingwa describes NFB-8 as "warm" as compared to "neutral" NFB-7, while the review at Pacific Walve mentions NFB-7 as more warm than Ref-7. Then imagine how warm NFB-8 must beExtreme heat
I did the 1ppm 80MHz TCXO upgrade to my NFB-1 (involves de-soldering and resoldering of the XO and 12 wires from the digital board). After the upgrade, it makes the NFB-1 sound warmer and thicker. Not sure if the NFB-7 with the 1ppm TCXO upgrade will also sound warmer.
The NFB-1 with the TCXO upgrade is definitely "warm" enough for my taste. For some tracks I actually prefer the sound signature before the upgrade
Thanks for sharing, interesting observations.
However, you may be better off waiting some days as things are likely to change, as Kingwa says "the clock burn in not myth, it is real effect the performance of the clock."

I fully agree with it, in the case of Sabre NFB-10ES the sound evolved from thick -- exactly as you describe -- to more sophisticated, more musical, layered and detailed. During the first week, each day made a difference, initially I did not like what I heard. Only after 7-10 days of constant playback I could fully enjoy music.
Is it supposed to matter if it is burned in with battery instead of just being used in the NFB-1?

Can anybody recommend the NFB-7 as a really good DAC well suited to serve in a high end system? I have bought the NFB-11 and the NFB-10ES for valuating if I like the ESS-chip, wich I very much do. Of course I bought them to listen and enjoy them too..
I wonder if anybody have experience of the difference between the NFB-10ES and the NFB-7... and how much difference the more sophisticated powersupply in the -7 really do.
