When using a power conditioner, why is it advised to run amps directly to the wall?

In my experience, I have great results running my complete system through my Puritan PSM156. I use two actually.

Everyone ' power situation is different.

contrary to ghd prentice there are a wide number of power conditioners that don't limit current at  all

these include audience audio magic and Isotek

in fact we demoed  a particular power conditioner with a krell krs mono block 

and there was zero degradation 

to date we have tested synergistic, shunyata, running springs, silver circle,audience audioquest, audio magic,and isotek, ps audio exact power and a few others

in all cases power conditioners elevated the sound of our reference system the differences were how the sound was improved they all differed in the way sound was improved.

Summation all passive conditioners made a greater improvement then direct wall hook up, 

all passives were better then active devices.

You’ll see this advice from a number of fire departments as well.  Don’t daisy chain power cords/strips and in some cases like space heaters or wall AC units, don’t use an extension at all.

The main reason for that is fire safety.  Lots of cheap extension cords don’t have a fuse at all, and are only good for a few hundred watts so it’s quite possible to overload it and the first you’ll know is the fire caused by melting wire.  You actually can do this safely but ONLY if your multiple extensions have built-in breakers or you are sure the wire gauge is greater than needed for the AC breaker in the panel.  Steps most casual home dwellers never pay attention to.  They need heat near their desk or dinning room table, out comes the $4.95 power cord and a few hours later they are homeless. 

Power conditioners restrict current in some way. I have even tried a couple power conditioners ’just for amps". The degradation in sound quality has been instantly obvious to me.

Now, in a home theater, it may not be as obvious. I find that being distracted by the video makes me far less sensitive to sonic nuance. 

S**t!  I’ll try again. MPC1500. 

That is an MOC1500 power control center.
