This has been in the works for a while, but today I actually got around to ordering the nCore 400 modules and SMPS600 power supplies- I've already got the chasis, special power cords, and a variety of other bits.
Chasis are being sourced from an acquaintance at Hexateq in Belgium; this was an early set before they got into officially supporting this Hypex module set:
I've been wanting to get back to this for a while, I've had the other "pieces to the puzzle" for over a year, but as we often say around Hacienda de Juan, "Slow work takes time."
In the past, these have taken as much as 6-8 weeks after order for delivery; I'm hoping demand will have normalized a bit and these might be available a bit more quickly, even if I don't have much time for 6 weeks or so to spend on something like this. We'll have to see how that turns out.
One of my colleagues we hired a couple of years back (a very nice/smart Danish guy) used to design Class D amps for another company; I know his old boss from 20 years ago. he's a bit incredulous at the performance specs for the nCore 400 modules, but then he used to do fixed clock designs with high performance conventional modulators, not a 4th order self oscillating Class D with the output filter inside the feedback loop- and the feedback loop being a fundamental part of the comparator.
I'll post more background data on the nCore 400 and info about the actual build as I go along. I don't have any other working Class D amps at home for comparison, and let's face it, I'm not interested in how good a Classs D amp it is, I'm interested in how good an amplifier it is, period.
