Active Hypex-Genelec - What SMP?

[UlrikSan]

Hello everyone. Thank you for hours and hours of interesting and useful reeding. I have finally come up with a question, I’ve been able to find answer for within previous posts:

I have a very soft spot for my tri amp Genelec 1022a, but the amps have aged 30 years and are out-dated.

An externally hosted image should be here but it was not working when we last tested it.

I wish to upgrade each speaker with Hypex-amps and a active crossover, DPS-dac .
I plan to build two mono blocks with 3x amps each: UCD180HG, UCD400HG and UCD700HG – all with HxG (I would prefer NC400’s, but with a total of six amps it’s over my budget)

Can I run all the units from one single switch mode power supply?

Each speaker is born with three less powerfull amps 7W/32W/150W.
Would it sound any different, if I used cheaper, less powerfull Hypex amps like 1xUCD400 for bass and 2xUCD180 for mids and tweeter?

One option would be 2 UCD180 and 1 UCD400 and 1 SMPS400A400 and 1 SMPS400A180 in each box. I think that would be plenty of power. The problem with running it all from one power supply is the voltage differences of the amplifiers.
