Audio-gd NFB-5, 9 switchable filters - Page 5

 

It might be easier to hear if you bypass the opamp.  Moon isn't very transparent.

Heard from customer service of GD that the first batch of NFB5 (20 sets) has already been sold out. Is anyone here the one of twenty?

Does the acss (and opamp bypass) work with rca output too? I don't care much about headphones, but I want a good but cheap dac/preamp for my speakers

I believe it can, if it can't i have no reason to buy one. I'll email them since I plan on using it with a LittleDot MK IV SE.

Please let me know too

From this list, it appears that you can have bypassed output.  See "Display 3" below:

 

DAC/HP switch: 
Select the output modes of the NFB-5.
Display 1 : Headphone output . Bypass the built in OPA, signal transmit by ACSS only.
Display 2 : Headphone output . The built in OPA active , signal transmit through the OPA convert to ACSS .
Display 3 : DAC output .  Bypass the built in OPA, signal transmit by ACSS only. Users can choice the DAC output either variable and fixed.
Display 4 : DAC output . The built in OPA active , signal transmit through the OPA convert to ACSS .Users can choice the DAC output either variable and fixed.

Dear Mark,
Sorry,the OPA in theroy just bypassed to headphone output
 
Audio-gd Sai

so whats the display # 3 and 4? it says the opamp will be active or bypassed. I dont get it..
 

 

#3: DAC output, bypassing the opamp

#4: DAC output, using the opamp

 

Not sure how to reword it, it is straight forward already.  The opamp is an extra, unnecessary component, mainly to color the sound to your taste.  You may find yourself liking output modes 1 & 3, since they bypass the opamp.  2 & 4 use the opamp.

 

No need to reword mate, I do understand what it says. What I don't is Audio gd employee saying it's only in theory for the headphone output..

Nfb5 has a pair of RCA outputs that makes it a standalone dac. The setting 3 & 4 is for the dac output. If in reality you cannot bypass anythg why would you put such a setting is what I don't understand

English clearly isn't their first language.

Yeah I guess thats what it is.. Anyway i think bypassing the opamp brings the sound a bit forward. This is with the. Moon opamp. Also I think I hear a very small difference in 9 filters. At the first setting the highs are painful but at the 9th setting it becomes smoother.

Impressions on the NFB-5?  Are they selling a bit because I wrote to them and I haven't gotten an answer yet...=/

Some time we can't receive the email at audio-gd@126.com.

So if after 48 hours still can't get the reply, please send an email to king-wa@hotmail.com.
