I don't think that true regenerator is necessary. I'd get a power conditioner with isolated banks and is also equipped with a voltage regulator.So I've had my Mjolnir for about six months now, or something like that, and sometimes it hums and at other times it's silent. I can't identify any pattern except the longer I leave it on the more likely it is to start humming. Now my mains supply is pretty poor, with solid voltage and low distortion but lots of other issues such as DC offset, noise and so on. I have a Running Springs filter, a balanced transformer, a PS Audio P3 (regenerator - but not a true one) and an Isotek Syncro (DC blocker). I also have a true regenerator (AC>DC>AC), but it affects the sound quality and still doesn't keep the Mjolnir completely silent so it's been relegated to the PC. If I daisy chain the first four of those together what could be getting through all of them to cause the Mjolnir to hum? I'm hoping there's an electrical engineer who can answer that!
Everything in the chain is plugged into the same set of filters (except the PC which is plugged into the other regenerator). I've tried assorted combinations and assorted sources, but with no luck. The rest of the system and my other components are all silent (from 3' away), so it's just the Mjolnir that's humming. I've tried disconnecting the PC from the hi-fi as well with no luck.
I also have an issue with the system sounding bright (through HD800s), again from time to time. I don't think there's an exact correlation between the two (that I can tell), but the same underlying issue might vary in intensity and cause both problems. I'm running balanced from the DAC and apart from power and headphones nothing else is connected to the Mjolnir.
The other filters all serve a function: when I moved in I assumed my hi-fi at the time was broken as it sounded so bad. Without any filters at all (and before I bought the Mjolnir) I had a 24/88.2 recording from Linn turn into a digital screech that was literally painful - it was unidentifiable as music. The same song on the same system after midnight sounded fine and I've not had a recurrence of that particular problem since filtering up. I believe it was caused by a combination of factors and I've dealt with probably all but one of them. This last one is doing my head in though, so hopefully the Mjolnir's hum will suggest a solution. Does anyone have any ideas?

I've had the same issues with all my Schiit products and solved them by simply going to a 3 to 2 prong adapter with all of them with no other issues--
No more Hum--

Is there no definite answer to this hum issue? Seems kind of weird that some are having this issue and others aren't. I'm definitely not, is this an amp issue or a home power issue?
