RockPower Power Supply Adapter NT 5 EU

I bought it as a future-proof power supply for my growing pedals chain.
I'm using it in the studio with synths so it's important to me to have devices that are not introducing additional noise.

I didn't notice any additional noise. I'm using it with 5 pedals (1 switch box so it doesn't even really counts) and synths that are quiet and I know what noise and interference each device introduce as I'm doing analysis in iZotope RX. The level of noise didn't change with this power supply. If it does, it's still below -70 to -90dB.

So if you're looking for a power supply for pedals in your studio that doesn't add anything unwanted, this one will do the job. I can't talk about guitars and amps.
