Hi folks,
Looking for ideas on the following.
I want to build a desktop system and envisage a pair of powered speakers to minimise wires, connections, enclosures etc. The main heatsink limits me to about 35W of heat so the choke loaded Mofo seems like a good/efficient choice. So assuming a 24V supply, I would be looking at ~1.5A through the MoFo. I anticipate a power supply capable of providing 3A to leave some headroom.
I plan on using the DIY FE2022 and want to build in some voltage headroom here too.
So the question is the power supply...
I could use two Meanwell SMPS supplies on each side to give 24VDC for the Mofo and 36 or 48V for the DIY FE2022. But I hope that there might be a more elegant solution that is relatively cheap and Noobie friendly to generate low power 30-48V for the preamp from the MoFo supply. In an ideal world I'd like to run the whole lot from a 24v laptop supply or similar. I'd really like just the RCA and power cable going into the box and not mess with mains AC.
So the question is how to get enough voltage swing from the front end/power supply.
As always, your thoughts and guidance are appreciate,
TIA.

Could I use something like this DLW05B-15 DC-DC converter followed by Mark's SMPS filter to drive the DIY FE2022?
Yes, the DC-DC converter would work as you surmise.
Honestly, I’d try everything on the single 24v supply to begin… you talk about it being a desktop system, so unless you are using particularly low-efficiency drivers and you like to listen turned up to 11, 24V is going to be buckets of power.

Thanks
and
secondly, thats what I figure. However, I wanted to make sure that
a; the o/s has enough current capability to address any `spikes' in the unpredictable music waveform without clipping. And
b; the voltage amplification stage also doesn't clip prior to running out of headroom downstream.
much appreciated.
