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. |

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: View List 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?
