Power conditioner types

Out of six or eight different brands of power conditioner that I tried, the Puritan PSM 156 was the only one that made an audible improvement to the sound.  This was immediately noticeable, and better in every way.

Puritan's power cords are also nice too.

Looks like I'm getting the Puritan 136. For my SS amp, it has more than enough capability. Thanks @hshifi - silver it is, and supposedly it will improve the sound over the Furman 15i.

@twoleftears - did you try the 136?

I have a PS Audio Power Plant Regenerator. I hunted it down and convinced the owner to sell it to me. One of the best things I have ever bought for my system.
Real black background, and this is through my all Tube system. Magic really. ;)

FYI, the Emotiva CMX-2 does DC offset removal for $129 and is a great product. If you have a conditioner you like, you can put the CMX-2 in front of your conditioner and get the benefit of DC removal without having to start over from scratch. 

@sokogear  No, afraid not.  Given the relatively modest price (compared to some others) I just went for maximum treatment/filtration.  Depending on the quality of your incoming electricity, some say the 136 is plenty.

There's a long thread on the 136 over on AudioCircle if you want to read more about it.
