PURITAN PSM156

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 that 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 your opinion would be appreciated.

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.

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.

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
