Gary, you are right, I have no fuses in my plugs, as you can’t fit them in a Schuko socket.

My system consists of my music PC, a digital interface/format converter, DAC, Pre amp, power amp for digital.
I do have a valve based phono stage on the analogue side.

So obvious plaCe would be pre and power?
They get used with everything.

My system as it stands:
Home built music PC
Audio GD DI-2014
RME ADI2 DAC Fs
Topping pre-90
Nuerochrome Modulus 686

All is cabled with OCC signal and power cables, except the DI, which has a Mark Grant power cable.

Analogue adds in my SL1200 and my BB3 phono stage.
