Power Conditioners

Take a look at a PROPER power supply for an amplifier here:

Everything you say you witnessed in the German power conditioner are ALREADY almost all in the power supplies of properly designed amplifiers.

Apart from extreme overvoltage protection and voltage regulation (as I said before, in this case you need to take your power company to court), there is nothing else to gain from spending on a power conditioner.

@dannad,

All large electrolytics are usually supplanted on their side with smaller hi grade mica capacitors around  0.1 -> 1uF to short out the hi frequency noise.

By rectification, I meant to say the peak value of any variation on the txformer output will be caught by the large filter capacitor.  Any hi frequency noise will be snubbed by the capacitors in parallel with the rectifier diodes.

99% of all amps have all these hi freq eliminating capacitors in place.

I bought a power Wedge years ago and it made a huge improvement in my system. When I bought a new system, I also upgraded to a Shunyata Venom strip. It has a Carling breaker to protect your equipment, in the event of a surge, and has a separate power filter that plugs into the strip, so you can use it with or without the power filter. 

Clean power is very important for good sound quality. How important depends on how noisy your electrical environment is. If you get this right then room correction/control, vibration and rfi/emf control being the other battles you need to fight. 

If you want to hear how you might benefit from a power conditioner listen to your familiar tracks then go to your consumer unit and turn off as much of the rest of your house as you dare. If you have stuff on the same ring as the music system unplug anything you can too. Now listen again. If you hear a good improvement then you can benefit from a power conditioner.

Cakyol please try this too. Modern electrics can be very noisy indeed. All those switch mode power supplies for our phones, tablets , routers, ethernet switches.... noisy. LEDs noisy especially if you have dimmable ones. This noise can be well outside of audible frequencies so may not always be measurable at the output of a DAC but this can play havoc with soundstage.

Eriks blog is a cost effective solution. I went for 2nd hand Isotek Sigmas gen 2 and DIY DC blocking power cord.  

My 20 year old Shunyata Hydra 8 was great.  Used it with Audioquest Hurricane and Tornado cords.  But, the power amp went directly to the wall.  Brought home an Audioquest 5000 and could hear no difference, no improvement.  Boy was my dealer annoyed when I brought it back. Sometime later picked up a Shunyata Denali... what a nice improvement.  Everything goes into it including the 150WPC tube power amp.  I think we all have somewhat different situations to be addressed almost by trial and error of equipment solutions.
