I have some questions regarding the power supply.
What is the difference with using a 12v or 18v supply?
For a lower voltage do I need a higher current?
Can I also use a 15v supply or does it has to be 12v or 18v?
I have some spare laptop powersupplies of 18.5v and 19v. If I would use them would I dammage the AMP?

HiFiBerry team You can use anything between 12 and 18V - also 15V. Be aware that some power supplies that are rated at 18V have a much higher output voltage if the load is low. We have seen already a case where a Amp was damaged by a power supply that was rated at 18V but had an output voltage of 22V. 18.5 and 19V might still work, but we don't recommend to use these.
The possible output power is a bit lower at lower voltages. However most people won't even notice it.
