I have a Steelhead and am quite happy with it, although it is kinda goofy looking. The remote will only control the volume, and no other functions, and only in the variable output configuration. It is by-passed in the fixed configuration. As for the noise floor/hum issue that you asked about, I had issues in this matter when I first installed it in my system. I tried placing the power supply in different locations in my rack, re-arranged/moved cables, all to no avail. I finally located the power supply out of the rack, and on to the floor in front of the rack. Problem solved!! It is now dead quiet !! The umbilical is plenty long enough for trying different locations. I have a picture of my system on my profile here, if you care to have a look, and you will be able to see it's placement better than I can explain it.
