I have been bench testing dual 24V MeanWell LRS-150F SMPS supplies on the F5m. On my test bench, with the stereo channels powered on for several days, I found that both SMPS supplies had shut down due to some kind of fault.
This might be a problem using two or more SMPS supplies that do not synchronize their behavior. Fortunately, the F5m channels survived whatever occurred.

This indicates another advantage with linear power supplies.

one B+ on out is a big problem :/ need relay syncro at last , as linear can lost bridge
 
The Meanwell LRS series is the least expensive of their chassis mount SMPS. There are other models that might be worth trying.
I used the the RSP-150-27 in one of my ACA builds. It was a step up from the 24V brick that comes with the the ACA kit, if not quite as good as the linear supply that I use today.
