After fooling around a lot mixing Oyaide plugs , can give you the characeteristic sound of the ones I know:
004 : Clean , ultrafast, a lot of data on HF , bass very controlled.
Using on both extremes : A bit harsh on bright systems.
079. Sweet . Great body. Great bass. Human voices are outstanding.
Using on both extremes: On dark systems and or tube based ones bass will be boomy and maybe a bit dark.
046: Is just on the middle of 004 and 079 , is more like the 004 tone.
Is neutral , fast, delicate, a bit more lust than the 004 (I like it).
Using on both extremes : No problems but is not as involving and inviting as combined plugs.
Using the 004 male and 079 iec , will get nice voices , a clean fast bass but with enough slam to be happy with it. Palpable instruments and dark backstage.
It is one of the best combinations out there .
The only time I disliked it was on a CD player that was extremely harsh , so I used the 046 as male.
Now to get the best on the Acrolinks I use
the same Oyaide plugs plus Furutech F-50's .
My best results are :
F-50 plug + Oyaide 079 IEC . Involving, inviting, seducting , SURPRISINGLY CLEAN ( considering the 079) .
F-50 IEC and 079 plug: Not as involving but acoustic instruments and voices never were so real.
F-50´s on both sides : Simply outstanding but don´t use that combo on all combinations of cords. System may go too polite IMHO.
