Hi
Can the LCDPS handle 2x18 volt in for 2x7,5 volt out in standard configuration?

If you by 2*18V mean AC in ~ 25V DC rectified.
Caps are 50V so they will survive. LM3x7 might be up to the task.
BUT- it all comes down to the amount of current drawn from the LCDPS.
What's the consumer ?

Yes 2*18V AC in.
The consumers will be 2*Opus dac. (and maybe also a Metronome asrc.)

Your worst enemy will be heat. You have 2 options.
1.
Give the Opus a little more juice.
pr. manual
"The Opus is designed to utilize separate analog and digital power supplies from 6.5V to 15V."
If you settle for 12v, you have less voltage drop across the LCDPS, hence less power to dissipate into the sinks.
The metronome is limited to 7.5v, although the onboard regulator is specified to be able to handle up to 16v input. (abs. max)
2.
Even better, play safe and find a 2*12v tranny.It won't cost you the world.
