Mile, I have Dynaudio BM15P monitors, they are 4 ohms and require 100-250W amp power. Which amp of your designs will be the best match for them for small home studio work?

Which preamp and PSU shall I use for this purpose? I had in mind Apex SR PP8, and for PSU I am not sure. Is there any PSU that can be used for both amp and preamp? Shall I use this http://www.diyaudio.com/forums/solid-state/222083-apex-hv23.html#post3212457 PSU with protection (first image on page) or this one: http://www.diyaudio.com/forums/solid-state/173462-studio-reference-amplifier.html#post2303230 ?

Which one?
Is this change significant compared to original schematic? I found PCB for schematic v1.0, and I am puzzled if this 1.1 is better and why? 😕
Also, do all transistors have to be matched, or only input / output pairs? Is it sufficient to match Hfe with multimeter, or they must be matched with bigger voltage and current?
Thanks,

Nice... can be use main power button..
What do i need to change if i use 12v/30amp relay?
2sa1943/c5200 for output devices limits supply rail to less than ~60Vdc, but I would not use them above 50Vdc.
Their high voltage SOA are terrible.
