Every amp is different... Just try it with different values and you'll know!

Has it been determined that bridging is an option with NCores ? I saw that the question was asked, but did not see a definitive response.

I have some large 84dB/4Ohm panels that I would like to drive.

emailtim,
I am pretty sure that Bruno has made the NCīs just as bridgable as the UCDīs. At least it was brought up as an option from the start of this thread.
Probably its the same procedure as with the UCDs -just with other cap values to match the O/P filter in the NCs, would be my guess...

It is undetermined whether it will have an impact on the sound, though.

Thanks, found the posts.

"... Yes you can bridge two modules just like UcD (and just like UcD it helps to strap a small cap across the load to insure the two amps synchronize). This would make a 1200W/4ohm amp (NC1200 is 1200W/2ohm). ..."

Just installed the caps on my input, after a minute or so of settling after turning the amps on I have nearly 0mV on the input and output, also no more loud pops when turning the amp on.
Thanks a million to all those who helped me out and guided me on how to fix this, everything appears good now!

I've never seen that. If the total ESR of the filter caps is no higher and the rail voltage is not lower, you should have no PS-related degradation, but rather improvement.

Glad it's working now!

Good to hear it works now! If I may ask what values did you end up with? 10K and 1.5uF or something else? Maybe usefull info for others.
