Class D and Me Too!... The Hypex Path

I have not seen that the NC400s need any buffer stage or additional OpAmp. They are commonly part of the builds using the NC500 and the Purifi Modules.
Quick perusal of the Apollon and Nord Amps using those modules will show you the same thing, along with how ATI is building theirs out: they use the NC500 Modules.

I know the ASR review of the NC400 build did not include a buffer stage, IIRC, it was a 2-Ch Amp with a shared power supply.
Thanks, I'll try to see if that was it.

More boxes:


Wonder what’s inside?


And then?


Hmmm... something isn’t right. The box said it was the right SMPS, but where are the Heat Sinks?




Ya... that’s not an SMPS600, that’s an OEM Amp Module, the NC250MP.

Hmmmmph.

And so I dig a little deeper...
They sent me two of those mispacked NC250s!
But that means I have 3 of the proper units!

Anybody wanna see?


Ok, heat sinks, check.


Yup!


Ah, yes.

Just get to it whenever you can...



No rush...



Don't mind us...



Any time now...



We'll just wait...



Dum-dee-dum-dee-dum ...



Yep! I'll just clip my finger nails while I'm waiting...



Take your time, I'm gonna get a sandwich...



Hmm, I need to clean the cobwebs off of the ceiling...



Whenever you're ready...





Good God, man, have ye no compassion!!!

You're killing us!!!

Yay! They got that right.
Now it's just the Chassis I have to deal with...
Trying to find out about Customs and the Ghent Audio Chassis. This is not a great time to be talking Chinese and Aluminum in the same sentence. I saw mention somewhere of possibly an 80% Tariff on the cost of the order! :eek:
Not so attractive.

DIY Audio Store has some interesting Aluminum Chassis options... these are coming out of Italy. I may be able to fit all 5 channels in the Chassis, which would be nice, frankly. The downside is that they are not readily available for Hypex parts the way the Ghent ones are. I am reaching out to them to determine if the work can be done (they offer Custom services) and how much it would cost to do. If the import cost from Italy is lower, the Chassis and custom work may well come out less expensive than anything from Ghent.
Without Tariffs, Ghent would be just under $500 for two Chassis, ready to go.
It looks I could get a basic 4U Chassis for $129 from DIY... then its just a matter of how much for the additional milling to be done for mounting the Amp components, balanced inputs, Binding Posts or SpeakOns...
*Sighs
Still a bit to go on this... probably not much in the answer department for another week, assuming I can get a customs person, somehow, to answer my calls!

'Til later!

I took the icepower boards out of the Ghent case. It's *too* overdone to the point of being predictable for my rather crude tastes. Welding/fabricating aluminum has been my day job for nearly 30 years. I am mulling over a design to make it my own but it will likely include welding. I could do something with stock extrusions as well but we will see.

My Pass DIY chassis I made in my back yard under the old oak tree. My kids will end up with these so, it's more along the lines of what they would expect of me. Hopefully, that adds some personal value enough to where they treasure it instead of hocking them for beer or pot. :D
