Power conditioner/strip

All instances I have experienced the amp was restricted by a power conditioner, even in instances when the power conditioner was made only for the amp and advertised no restriction of the current. They always sound better plugged directly into the wall, Tube or solid state. 

you might want to try a PS Audio Power Regenerator. They see to get good reviews.

How about buying an actual power conditioner that meets actual, stringent standards and specifications?  I dont know what your power requirements are so ill just use a somewhat worst-case scenario and suggest an Ametek Powervar ABC1200-11 or heck, make it the ABC1200-11MED for even higher spec and reliability.   These things are big and heavy.  I have the ABC830-11, and it's also bear to lug around on account of the giant windings inside, paired with physically large film filter capacitors.  I dont have a picture of the guts handy at the moment, but these things mean business, and the company sells to industry that has to meet requirements, so they dont try to pull the wool over your eyes with whiz-bang features that dont accomplish anything. 

A power conditioner will do nothing but potentially inject nose into your system. You cannot 'clean' power. It's a fallacy.

@mlapenta you haven’t stated what you are hoping to improve about your existing power conditioner.

With limited info on the problem we’re solving here, I would suggest either a used Puritan or a used Shunyata product up the line from the one you are currently using.
