Hi all!
I must do a follow-up-writing on my NFB-11.32 burn in...now since 6 days (~140h).
The NFB-11.32 has matured much better than expected. I almost want to say that it is irritating that this piece of equipment can sound this good. On headphones HD650's I still think it can add more "space" to the scenario.. But as a dac....
At this very moment the NFB-11.32 is fed through with one Logitech Squeezebox Touch w. "EDO" asynchronous via USB as in my earlier post. Now I am using it as a dac, connected to a NFB-6 preamp, connected to a Master-3 poweramp. On another input (XLR's) I am using a Ref 7.1 fed in the same way but different USBchip(Tenor8802L).
The Ref 7.1 sounds great... And Yes it should do so (otherwise I should be very disapointed).. But switching between these two channels on the NFB-6 (well burned in) gives in my opinion "too small difference" on the same musicmaterial. Read this in a positive way, as it's meant and don't misunderstand this. What I mean is that the NFB-11.32 used as a dac are competeing with one of the best dac's out there for reasonable money, and it can stand tall in this comparison. The Ref 7.1 has a bit more body ...but when listening to Diana Krall and others on good 24/96 and higher-recordings are fantastic on both (!) chains.
I think some of the success are the joint chips USB-32 and ES9018 that gives this super result.
Today I also noticed on the Audio-gd-webpage, new products listed with the new USB-32-inputs built in. There is no doubt Audio-gd are higher the levels of soundquality in the USB-area right now.
I think the future is I2S in dac's, in one way or another... (I2S-in or USB asynchronous) served from the net/Internet and Audio-gd lines up for this future.
The NFB-11.32 will continue the burn in and....I am not sure I want to have it any better ; )
Stay tuned.
Thanks for reading
