It's fine, but a separate front panel switch doesn't complicate the situation much either.
No need to use J1 unless you want to be able to force the system into standby, or want aux power for a front panel light or something.
And it has been several places allready and they love it. One allready put an order. I have heard the Icepower 1000 with switchmode supply. It made my stereo sound like a clock Radio . 😀
No Hum at all even at 108 DB system with NC. In my room and with my speakers I need more power.
they why not bridge 2xNC
Maybe bridging two ncore´s per channel could do the trick for you.
They can deliver 24 A´s so unless your speakers are of very low impedance, bridging two ncores should provide significantly more head room...

You need more power than the NC400 ?
I guess you must have some very low sensitivity speakers, or you want to play loud as h***. I rarely exceed 10W even on my 88 dB ribbons.

My speakers is able to make you jump in the sofa with the right amp. Nc did not do that job ( another pre maybe ). They are 88 DB to.
You have to hear my system to understand what I am talking about. Basreflex are seldom able to kick ***.
Ups now users are going to kick mine ! 😀

I have a 84 VDC and a 77 Vdc powersupply with 2200 W transformers and 140.000 uf. for each mono amp. Want to use those supplys somehow.
Well I just ordered some other moduls. If it where possible to buy the NC 1200 I would have done that. My Coldamp can not follow the NC in midrange / treble.
So the NC is the better amp compared to your modified Coldamp, except for "big dynamic jumps" where a lot of power is needed? You are using 900VA transformer per channel at the moment isn't it? I can't immagine you can improve with even more power of the transformer.... Doesn't the big capacity make your amp "slower"???
You don't feed it with the same voltage as the SMPS600 provides, is it? You give away some power because of that.

990 Va U core. If big capacity make Amp slower also depends on the moduls I think.
I do not give a d... 😀 . I once made a Tripath with 1 / 2 F a fantastic amp.
But it had some " children problems " some of the first on the market.
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 NC´s just as bridgable as the UCD´s. 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!
People reach across borders towards a common goal! It's inspiring, just to die for.

TITANIC 'UNLIKELY' TO SINK AGAIN, says prof -- http://www.theregister.co.uk/2012/04/10/titanic_unlikely_to_sink_again/
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.
