Hypex recommend 1x SMPS400A180 power supply for 6 x UCD180 modules, so you may not need 6x power supplies for your application. The mids and tweets do not need much current. Don't worry about having too many watts. Better to have too many, than too few.
Only smps1200a180 can power without limitations, 6 ucd180 modules (datasheet pag. 11 e 12, sez. outpower) , the smps400a180 can feed, 2 ucd180 modules.
Hypex themselves stated to me that 1x SMPS400A180 would be fine for 6x UCD180. Can't get better confirmation than that methinks.
After building six or seven Class Ds and selling all but one (which I like) there are better sounding in your/my system Ds. Amps and spears are a marriage get right and you're in heaven. No need to start e the other alternative.
BUT, BUT, BUT, BUT, BUT, I would only ever employ linear PSs. And I would suggest Tripath Ds. They are beating the best SS amps around. Look out for reviews.
Should add I'm about to finished some Tripath T3 150W momoblocks with 44,000uf of ultra low ESR Mundorf MLytic caps.
I see there a lot of investications about D amps, I had the idea when without feedback making digital a triangle signal because when it is precise and liniair the amp give the lowest distortion.
Neat a power dig to an converter.

The amps I'm talking about are not digital they are switching amps. You can buy digital amp modules though.
Yes I mean class D amps.
A triangle is used as input for modulation, this has to be a very presice signal because it has direct impact on liniarity. Making this digital with a pcocessor is maybe a way to get a low distortion class D amp, even without feedback. I have to say also that the death time is also a uge factor for distortion, use of a extreme fast mosfet is needed to get as less death time as possible.
In principle it is a digital amp, it is a power digital to analog converter with use of demodulation coil.

Hi, someone has tryed the combo sure ab32512 with mw hlg 320 36a? It could be better than my nad c355?
Thanks

Here are some images of my latest Class D; a T3 150W Tripath monoblocks. The PS for each block is rated 420W and each module will deliver 300W into 4ohms and 150W into 8. The caps are Mundorf MLytic 2X 22,000uf, ultra low ESR audio grade.

I have tried tripath. This is the best sounding non UcD I have ever heard. Some people say this is like tube sound.
I wonder if it was the voltage difference or different PSU design. The HLG is a Led Driver. I have found a led driver that is 36v but 120watt and 4amp. Would this be enough? This 320h model one is very expensive. More expensive than the amp itself🙂
I hope this is not concidered off topic: How does a ClassD amp distort?
Is it mostly even or uneven harmonics ?
Thanks in advance
Arthur.

What you descirbe is how class-d amps would be made 20 years ago. Today class-d amps do NOT use at triangle generator.
Modern class-d amps are self oscillating build around a integrator (op-amp).
