Can anyone tell me will i benefit from swapping the 0.47 uF polyester input caps to some wima mkp10, they are 0.47 but rated at 250v, will this be ok, space is not an issue, also will a cap change on the supply board improve sound, currently they are x6 2200uf at 35v, should i try some better quality or larger caps? really appreciate any input as im stumped.
