Re: Wry smile. Thanks, briggs. Much appreciated. [nt]

In contrast, Zero ...

20 years ago, when I built my house, I installed a dedicated 20amp circuit for all my source components (it feeds a row of 10 single oulets mounted on a long, hollow wooden wall plate). The wire is about 20' from distribution box to the start of the wall plate.

From corresponding with various people in the intervening time who have made serious mains-power upgrades, as I am now undertaking major renovations to my house, I have taken the opportunity to replace this 1 x 20amp circuit with 2 x 32amp circuits. One will be for analogue comonents such as phono stage and preamp, the other for digital components such as CDP and TT power supply (and spares).

Power amps are on their own 32amp circuit ... AFAIAC, the current draw from power amps compromises the mains supply to source components, so they ideally should not be combined (remember, conventional power amp PSes recharge their PS filter caps in pulses, so that even though the amp might only be putting out a couple of watts, it IS drawing higher mains current than the simple maths would indicate for milliseconds, 100/120 times per second).

So I would suggest you can do better than briggs' suggestion of a single 20amp circuit for everything.

Regards,

Andy
