You cannot tell how a cap sounds after 3 hours. Modded Wima caps need a couple of days before they settle down. The value of the bypass cap will also effect the frequency balance. Generally the smaller values add air and as you make the cap larger it will add some warmth. You must damp the bypass cap and the main cap. You cannot dangle a cap in the air on bare solid core leads (it will act like a pitchfork .....this will sound bright and horrible). You must clamp the bypass cap down (and not with double stick scotch tape...this ruins the sound) and also you must damp any solid core lead on the bypass cap with cotton sleeving (unless the leads are very short).
