nice job!
we are also manufacturing some amplifies based on NCore 500 for domestic use. could you please light me up what is the best way to have a LED pilot?
BTW, have you every considered a bridged version with two NC500 per channel? it will deliver 1400watts@8 ohms with about 50Amperes of current if I'm not mistaken! it would be a killer and may outperform even a single NC1200. any idea?

I am trialling the NC500 for our DEQX-active Legend Tikandi loudspeakers. A few years ago we used the UcD400 modules on these speakers but I was never overly happy with them, feeling they lacked punch in the bass and were somewhat ‘grey’ over the rest of the frequency range. However as their hype suggests the NC500 are in a different league with a very clean, neutral sound and very fast dynamics.
My only problem came during their construction. Along with a pair of NC500 modules I also ordered their SMPS400A400 switch-mode power supply thinking this would provide enough power for my needs as I had used it previously. However Hypex did not advise me the SMPS400 would not be suitable as they have moved some of the power supply functions from the amp modules onto the power supply modules, apparently to reduce the heat dissipation on the amp modules particularly for when multiple amp modules are used in the same chassis (as in active speakers such as ours).
Unfortunately I had already started the build (2nd image) before I realised this and more unfortunately the required SMPS1200 was too large to fit in this box (as well as costing more than 2 of the NC500!) so I decided to build a linear PS with bits I had lying around, including a 500VA transformer that also happened to have the required subsidiary secondary outputs needed for the NC500. The result was not pretty (1st image) at least partly because Hypex also did not supply the leads needed for the complex 36-pin header on the NC500.
But as I said the SQ was extremely good and well worth it!

OK here is the final layout...
Its not finished the switches I ordered were on back order so there will be mains wiring to the front panel and some power for the LED. Much neater this way and cables much shorter. Cable routing and loom will be next once the switches arrive. XLR's in place some high quality Switchcraft Gold plated metal bodies courtesy of a great little supplier Action Hardware who are also the CHK distributor in the UK the mains IEC switch input come from them as well. XLR's sounding much better.
Next up is design the packing and get it on order.
Sounding wonderful. Enjoy.
What is going on with your safety earth connection? With all that free space I would provide more distance between the PS and amp module.
This was not a finished item! The final production layout is slightly different. Hypex have given it the green light. There are many considerations when laying a design out, the input buffer board can not go across any further there is a switch sticking out of the side of the board. Any way here is a finished amp.
Hi Boggit
My friend just installed the v5 BURSON into his Tag McLaren DPA - removed the LM4562 that was in there.
Said better focus and less sibilant so far
It's hard to tell if LM was just not fit for purpose in there as this was really OpAmp 'rolling' ...but at least it's not sounding bad!
One issue, the v5 has a non-removable red cover, so he struggled to fit this in next to all the WIMA Caps! Let's hope enough clearance in around the components in this Buffer :-D

Fantastico! Just a warning as it caught us (him) by surprise :-(
BURSON website images allude to the cover being removable!

are you referring to the capacitance in the supply with your V2 amp?
There may be a reason for note 1 at the bottom:

Just to say the Standard versions are now available for purchase. I will offer a no cost upgrade to the new Input Buffer Board what I mean is that it wont cost any more than purchasing the upgraded version from new. I will stand the cost of the Hypex Buffer Board. I'm not in a position to give final cost of the upgrade but I think in the region of £250 for 2 mono's or Stereo Amplifier.

Bridging doesn't increase the current capability, only the voltage swing, so the current limit would still be 26 A.
thank you for explanation. does bridging affect the sound quality? any chance for a better sound?
"Maybe" 🙂
The main effect is that it allows you to go 3 dB louder before clipping, so if you are normally close to clipping, it might give you a better sound - just be sure your speaker can take it.
There is also the view that you get a cancelling of certain distortion harmonics, but at the extremely low levels of distortion that we are dealing with here, it will not make any difference.
I have not tried with Hypex amps yet, but 2 of my Abrahamsen V4.0 power amps are pretty special. More Bass and a huge sound stage both in width and depth. Obviously more drive. You need a big room though. Sometimes more is not better.
Hi Boggit,
The Nord One NC500m MB Amp switch in front, it turn on/off the main electrical supply or just mute and un-mute the amp module ?
Another subject - Did you manage to compare the SQ different between the NC400 vs NC500 ?
EH.
