And your experiences and point of view are appreciated
But yes, I have been following everything, but I see no advantage to the better FFT result over the Hypex. So conceivably both exceed the specs required by the amp modules wherein they will not contribute negatively in any audible way, but one measures slightly better so it is possibly, but not confirmed, that it contributes even less negatively so it is even more inaudible. Do we have any proof or data that a psu design that betters the Hypex psu affects the amp modules output in any measurable way?
Surely Hypex has designed their supply to not affect output of their fantastic amp modules negatively, right?
of course the above comparison has no bearing on my initial question as it does not address the Mornsun in any way.
I see no benefit of any kind to running an unregulated PSU (micro) vs the regulated Mornsun, except of course that the Mornsun can provide a very highly efficient 400 watts all day long before thermally induced derating and it is a medical grade product with a high MTBF, with a higher maximum power output in a smaller package for a similar, if not lower price.
I have no idea what the Micro Audio can put out beyond knowing it has a fan cooled 630 watt maximum. This especially concerns me as very few of us ever install cooling fans, so what do I really have here with the Micro Audio passively cooled? 200 watts ? 300 watts? I have no idea as their is no data given with measurements taken adhering to established protocols
I have no reason to think the overall quality of the Micro Audio is superior or that it will last longer than the Mornsun or for that matter the excellent Hypex PSU
I do feel the Micro audio appears to be a high quality unit overall put out by a company that builds very fine products
for my 3 channel mono module build I will likely chose the 750 watt Mornsun as I don't need more than 200w x3 absolute output plus a pinch of headroom
Choice is yours ) 750W makes sense for a 3 channels amp.
In any case and as I have already mentioned. The TPA325X Sylph and 3E Audio modules have excellent PSRR, which is why brick type PSUs (with mediocre ripples) also work well on these modules (CF. PA5, PA5 II or PA7 plus).
Concerning the 3E Audio power supplies, Sami will be better able to answer you... he's the designer) Even if we actually lack a little information on his PSUs, they exude quality when you have them on hand. @MicroAudio > any inputs here ?
EDIT :
Found the FFT for the LOF550-20B48-C
@IDLE
@5W / 4R
