PURITAN PSM156

Current draw is essential to burn in. Each outlet will also benefit from individual current draw, I am guessing not a lot though. Time is priority, not amperes from my understanding.
Be patient and plug in what you’re going to use in it and play away.

Enjoy!

12 to 14 days for burn in the 156 means constant current draw from the unit 24hours x 14 days, am I understanding correct or just switched on for 14 days

I would not add bypass caps to those Jupiter copper foil caps on the output of your preamp. Stick with one good cap in that position. Bypassing can be good or not so good and I, perhaps nobody, has tested those two caps used together.  

It's break in as grannyring described.  I had the same issue with mine.  Also see the attached video where they talk about the glare at 12 min and the result after break in at 17 min.

@grannyring will report after 2 weeks and the jupiter copper wax in the pre are fantastic Chris has some new silver oil which he made lately with lower value .01uf should I bypass the copper with his silver caps do you think they will make a difference.

The OP is just dealing with burn in.  OP, please update us in 2 weeks.  

It will sound more fleshed out and not so lean after 10-14 days of use.  Needs run in time! Starts off thin or lean sounding.  No worries. 

No worries, i understand you well enough. Are you running your entire system thru the 156 ? try a single component direct into wall, one at a time. Start w power amp.

Best to you.

Dear friends off lately I had installed the PSM 136 puritan power conditioner and was very happy with it, the sound was well separated, cymbals had that shhhhh to it and the noise floor was very low, 

Considering all the above fact I went one step up and purchased the PCM 156 with the ground master.

I installed the same for the last 3 days but I somehow feel all the traits of the PSM 136 is missing What should I understand from this is the PCM136 better or does the PCM needs more break in your opinion would be appreciated.

Not sure if English is your native language,  but your post is one very long sentence as there are no punctuation marks.  It was hard to comprehend.
