@Vladimir Filevski (2x155)+(2x300)=910

Where is the 910W
difference?
A I said earlier, you can not add amplifier wattage like that - it is meaningless!
Your first proposal was 150W amplifier (per channel) for Elac DBR-62 - that is about the same as the Neumann KH 150 internal 145W amplifier for the midbass. Regardless of the subwoofer wattage, DBR-62 will receive the same 150W, so it can not be louder above 100Hz.
Your second proposal was 300W Hypex amplifier -
that is only 150W difference and only 3 dB higher SPL,
if sensitivities of both speakers are the same,
if power compressions are the same, and
only if Elac DBR-62 will survive 300W input power (it will not - given the unexperienced user, as OP is).
You forgot Elac's won't do a bottom end (100 Hz crossover) which give them at least 2~3 dB more.
I didn't forget the crossover at 100 Hz, and also I didn't forget that the 150W (or 300W) amplifier for the Elac is the same (with or without subs), so there can't be "2-3 dB more" above 100Hz in this universe with these physic laws.
They survived turture on 1 KW monoblock playing on ear bleeding levels.
You forgot OP is not an experienced user - with 1kW monoblock he will surely fry the speakers in a heartbeat.
Two SVS 1000 SB will be able to go 106 dB @ 31.5 Hz and 109 @ 40 Hz.
So? Does the OP need them? Does he need measurement microphone, MIniDSP, two subwoofers, etc? As far as I know, he asks for a pair of good bookshelf loudspeakers, nothing else. No two additional big subwoofers, no additional DSP, (he doesn't know how to set up the MiniDSP crossover, for sure), no additional fuss...
You can find desired measurements you referred to as missing simply by reading their review's hire at ASR but I am sure that you already know that.
I have listened both speakers, ASR (and other) measurements confirmed my subjective thoughts.
I find your comment's not polite, to say the least especially as I am certain that you know better.
