Roy, you've got both a COLOR and a USER tag in your posting that's causing the formatting problems. Right at the start of the text they appear as a pair: color= and user=. At the very end of the text they appear again as /user and /color. Delete the whole of these at both ends, including the square brackets that hold these tags. The color tag is relatively harmless, but the user tag is creating the clickable link.
In my experiments with ferrites I've found that "not enough" of them can result in a sound quality that isn't harsh, bright or fatiguing, but has a kind of hyper-realism to it. It's almost like a sheen of explicitness has been added and can be heard as increased presence, air, hyper-detail and a sort of etched three-dimensionality that makes singers/instruments have a kind of "stand out" effect, separating them from the rest of the ambience in the recording.
It's very pleasing in the short term, but from time to time this presentational style will draw attention to itself as an effect.
A Chord DAC always does the same thing when you feed it with less RF: it sounds darker, the soundstage expands and transients get faster.
So when you hear these things you know it's working better.
It will often sound quieter, too. The quietest sounding of two systems is often a big clue as to which is working better. When one system urges you to turn it up louder, that's the one you want. Distortions from the lesser system, even when the volume control hasn't been changed, are causing a kind of low-level confusion which is heard as an unexplainable loudness, as if it were a minor irritant, not overtly perceptible but subtly wrong all the same.
It'll only take a few weeks to adjust.
