On Kenster's suggestion I tried a small 1cm long snap-on ferrite on the ground wire coming into my balanced power transformer. My digital stuff (DAC, transport, DVD player) is all plugged into it, whilst my amps are plugged directly into the wall.I wasnt expecting anything immediately noticeable, maybe just a cumulatively better result along with the balanced power. But the sound was immediately different! A more dry sound, better upper midrange presence, tighter bass.
Since I had been inter-state for a few days I thought that I had forgotten what the system sounded like and gave it a couple of days. Still seemed very different, so I took it off. The sound went back to how I remembered it previously. I put it back on and added another ferrite next to it, again very different sound but had the same effect as the single ferrite just more of it. But a bit haggard in lower treble, too dry. I tried a single longer ferrite, which was better than two. Then I went back to the original short ferrite - less seemed to be better. Then again with no ferrite - so much warmer and liquid, but maybe too much so, like it does need 'drying' up a tad but not as much as the small ferrite provides.
So I am on the hunt for an even smaller ferrite to try.
I dont have any idea why this has such a dramatic effect (I even blind tested on my partner, who could also pick the differences within seconds). I theorize that it stops RFI into my DAC (which uses the ground), or maybe stops RFI from all the front ends from getting back out to my class D amps (CI Audio D-200), but really Im clutching at straws here as I cant believe that just RFI is creating these dramatic changes.If anyone else feels experimental about ferrites on the ground wire, please try it out as Im shocked at how dramatic the results are. Im also aware that trying a smaller ferrite might still not end up as good as no ferrite at all, but it has been an eye, sorry ear, opening experience and worthy of further investigation.
