Good small/single outlet power conditioner for preamp.
Anyone know what’s out there?
I am demoing a very nice preamp but it, for currently an unknown reason, does not play well with my Puritan PSM156 conditioner. The pre exhibits noise/hum from the speakers with any source ICs plugged into it.
But the preamp straight to the wall is hum free and all is fine.
If I wanted to keep this pre, straight to the wall is not ideal. So I am preliminarily curious what nice small/single outlet power conditioners are out there for me to consider…
thanks
Hi erik. All components are into the Puritan. But now with this new and very nice preamp I’m demoing, there is hum when a source is plugged into the pre. Take the pre straight to the same outlet the Puritan is plugged into and no hum. It’s a weird one, as this conditioner has never done this with other preamp or anything. I’ll look at Furman but I had a a 15i or 20i Pro years back that I thought sounded ‘mechanical’ in the end. |
@jriggy It sounds like there's some sort of offset being created in the puritan, which can happen when you use a balanced power conditioner, but it usually makes things better. I recommend the Furman because of it's 5-star surge protection and that I've heard it when absent. Is there any other external copper connection coming into the system, such as a TV or coaxial cable? Ethernet is OK. |
@erik_squires No, not on this deadicated circuit. Just the system: a CD transport and its LTA ps, an AppleTV, an IFi spidif Purifier, DAC, pre and amp. |
@erik_squires nope. Dang it, I had some hope with that one…
Anyone know which power conditioner is considered the competitor to the Puritan 156?? I guess I could always try that one… but I’d have to commit to this preamp first and then pray that it is compatible with the new conditioner. |
