There have been some Sansui owners who didn't like the sound of their amps & receivers after a recap. As the capacitors age, the sound becomes muddier and less accurate. Some owners get used to this sound but since the sound reproduction is no longer accurate, it is technically distortion. Not that all distortion is bad, in fact, merely adjusting the bass/treble could be construed as distortion. In any event, because the change in sound is gradual, the muddier bass & loss of treble is gotten used to. Upon a full recap, some owners dislike the "new" sound saying it lacks warmth. In fact, its probably closer to original after the recap as amps should be as transparent and color free as possible, with sound shaping being introduced deliberately and not as the result of an aging amp components. Bottom line is that as long as you like your bug, it can be to you as a feature. But I don't they were that way when they were initially released.
