Would it make sense and be safe to put power conditioner in front of PS Audio regenerator?

a dedicated line does almost nothing to improve the quality of the power--it ensures that you have adequate current.

Strongly disagree... Depending on the wiring method(s) used for the in and out branch circuit wiring connections at every wall outlet box plus ceiling lighting outlet boxes of a convenience outlet branch circuit a dedicated branch circuit can make a big difference.

@jea48 and @carlsbad2   -  I agree.  Straight from the wall to the PP.  12 awg or heavier power cord with solid plugs on both end from the wall.  It doesn't need to be a very expensive one because the key thing is to get the needed current to the PP.  And as @jea48 mentions, a worn out, light weight, loose receptacle should be replaced.

Not in front of–but you could try beside. Use one for the source, the other for the amps. Use same twin outlet. Also try direct to the receptacle with no conditioners. 

I see. I won’t do it. I use Purist Audio power cord from the wall to the PS Audio Premier and the connection is tight.

Without the regenerator it is incomparably worse, everything should be plugged in it.

This brings up a thought after reading the post.

I assume the output of the PS Audio regenerator is wired as a grounded AC power system. Therein NOT left floating. Floating...Therein two Hot ungrounded conductors with no reference to ground.

If the AC output is a grounded AC power system (which I hope it is) and not all audio equipment that, is connected together by wire interconnects, is fed from the regenerator, like say a power amp that is plugged directly into the wall out, are the two 120V power sources in phase with one another? 

Simple test. Use a multimeter, (set meter on AC volts auto scale, or above 250Vac scale). Measure from a receptacle HOT contact (small slot) on the regenerator, to the HOT contact of the other receptacle of the wall duplex receptacle the regenerator is plugged into.   

If the two 120Vac sources are in phase with one another you will measure zero Vac nominal. If the two 120Vac sources are out of phase with one another you will measure 240Vac nominal.
