Hmmm (pun), which Isotek did you try? I have no discernable transformer hum but I am nevertheless intrigued by the Isotek Syncro and have one coming in two days to go along with an Isotek Aquarius. I do have some very slight hum through my speakers, not enough to hear from my listening position. Having very sensitive loudspeakers never helps and I do believe that with sensitive speakers and tube gear, some low level hum is inevitable. I have DeVore 0/93's and an ARC Ref 150SE. The biggest change in hum level came with-of all things-a switch of equipment rack. I went from a cheap MDF shelf rack to a Symposium Osiris Ultimate which Peter of Symposium says features a Faraday Cage effect as well as vibration isolation. I shrugged off the Faraday Cage thing as so much typical audio hype, but it seems to be true. My amp is not on the main rack but in front of it, so I am left thinking that one or more of my other components on my audio rack were interfering with each other and causing the hum. They consist of my preamp, phono stage, and DAC. 

Fsonicsmith we sell the Syncro and to say it is remarkable is an understatement.

It does a lot more than just block dc.

One of the best things you can do to elevate an entire system.

That was my thinking too-that it likely doe more than just block DC. Thank you for the support-now I just have to hope you're right. I am getting excellent sound now. On well recorded material, my speakers disappear and my soundstage is wide and deep. Bass is taut. Transcients can be startling. So, I figured I had nothing to lose and you never know what you might gain. On a side note, I gave you some grief on a different thread (Elac Adante). Thanks for being nice to me. I will try and return the goodwill. 

I upgraded my Furman power conditioner to the P10 about a year ago and while the difference wasn't dramatic, it was noticeable and positive.  I'd say the biggest difference was "blacker blacks" to use a video analogy if that makes sense.  It was if the music was emanating from a cleaner background.  I do get some hum from the transformer inside it sometimes, and while I wish that wasn't there, it isn't very noticeable.  I'm maxed out on outlets and power capacity of the thing, but I'm running 6 amps off of it (2x mid/high, 2x mid bass, 2x subs) plus many less power hungry components.  I could use a P20, but I don't have the room in my rack.  I recommend the PSA gear, though the trusty old Furman still works too (and is now moved to the 2nd system)
