Power Failures

I had one of my Proac D15's blow their mid-bass driver from the turn on thump through a Naim amp. Even though it states in the owners manual that no speaker damage can occur from the turn on surge, it did happen with my speakers.

After that incident, I would unplug my speaker cable from the speaker end and then turn on my equipment, that's the main reason I left it powered on all the time except when storms were in the area.

Although your system may be powered down incorrectly in a power cut, if there's enough time to switch each box off, you can at least observe the correct power-up sequence (source first, power amp last) after the supply returns. Having said that, outages only seem to last a few seconds here, so there's not much you can do about it. 

So, I have decided to move my battery/surge protector to my system. I am plugging my power amp into surge only, and my pre into battery. This way, in event of a power failure, the power amp will shut down first, and the pre wont shut down till the battery dies, no more pops .

We have many outages over the summer as the grid cannot handle all the A/C units running, so I must protect my baby Elacs. 

Just to throw in a complete curve-ball ... my old flat was a devil for having short duration power cuts and when the power came back on and all my amps came back on at the same time the switch on surge would take out either the sockets breaker or main breaker and then leave the fridge and freezer to slowly defrost...

What I did was use a couple of these...

...mounted inline to the distribution blocks that I was using for the HiFi. Basically they are a no-volt release switch so when the power is removed they simply switch off so that when the power comes back on the connected devices don't power up again, then you can make sure you power everything up in the right sequence and not have kit flicking on and off if when the power comes back on it's not stable.

That is very handy. I should actually look into the unit I just installed, it has some programmable features, maybe one of them is to not power back up. 

So, I was running a Tripp Lite ISOBAR8, based on its great reviews for audio. The thing was noisy as hec, by far the loudest thing in my system. So not only is that annoying high pitch buzz gone now, but, so is the buzz my nac202 did when I fired up the TV, now, it stays dead silent. Sound quality seems unaffected. Guess I should have done this sooner

I live in a location with lots of electrical storms in the Spring and Summer, so all of my equipment is protected using Audience products. Whenever I know a storm is coming I turn everything off and unplug the Audience units from the wall.  That said, there are lots of times when I am unable to turn off and unplug before a storm hits, and I have lost power to the hifi gear on numerous occasions... but it's always been protected so haven't had any problems (knock wood).

Hi, what is the Audience product? The day before yesterday, I was hit by a power outage. It came off and on again within a fraction of a second while I was listening to loud music .  Phil recommended a gadget switch, but that one is not available in the US.
