Thanks again
.
R141=Rg=1.2k
Rf=2.2k
for the NC-400 model
that is what I found in one of the Brunos post
Yes There is no need to change the Rf i was just curious
Thanks
now it is clear
I just need +3db additional gain...

Just be aware that increasing gain lowers the feedback. While Bruno has commented that increasing feedback is OK, I think you might be in somewhat uncharted waters if you actually lower the feedback from the nominal.

Very interested in hearing your experiences if you try it.

According to the present datas should be something like this
(for the 680 ohm Rg, +4db input stage gain)

Hi,

Quick question. Can someone point me toward the connector for J1 on the SMPS? I have looked for item # JST-B7B-EHA on Digikey, with no luck. This looks like it, but not the correct item #. I seem to have thrown out the ones that came with my units and need them now.

Thank you

While we are at it, would someone know the exact reference of the female crimp terminal to use with the microfit molex connector 43025-1200 ?
I think it is the 43030, but several version exists:

What is the AWG of the wire?

I would like to fit 2 (or myabe even 3) wires per connector, so if the original AWG is 24, 2 of them should fit no problem in the 20-24 AWG model...

Also, do you know if special tools are required to assembled those crimps, or will a simple crimp tool be sufficient?

My 3 monoblocks with bridged nc400 and SMPS1200A400, built by my friend Georg.

We have compared them against the standard nc400+SMPS600 in a dual-mono config today. The bridged ones sounds much more "alive", and they are not even broken in. The standard ones sounds flatter. Less dynamics.

The monoblocks has version 4 of nc400. The dual-mono has version 3. What was the changes made in version 4?

Did you do the comparison as a double-blind ABX, or as a sighted subjective evaluation?

I am missing the cap across the output terminals!
